Case 1: All switch ports are in the same local area network.
Every port can access each other. (*The switch image is sample only.)
If VLAN is enabled and configured, each node in the network that can communicate each
other directly is bounded in the same VLAN area.
Here VLAN area is defined by what VLAN you are using. The switch supports both
port-based VLAN and tag-based VLAN. They are different in practical deployment,
especially in physical location. The following diagram shows how it works and what the
difference they are.
VigorSwitch P1100 User’s Guide

Case 2: Port-based VLAN -1 (*The switch image is sample only.)
The same VLAN members could not be in different switches.
Every VLAN members could not access VLAN members each other.
The switch manager has to assign different names for each VLAN groups at one
switch.
Case 3: Port-based VLAN - 2
VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.
VLAN2 members could not access VLAN1 and VLAN3 members, but they could

Users can monitor and configure the switch through the following procedures.
Configuring the Management Agent of VigorSwitch P1100 through the Ethernet Port.
There are two ways to configure and monitor the switch through the switch’s Ethernet port.
They are Web browser and SNMP manager. We just introduce the first type of
management interface. Web-based UI for the switch is an interface in a highly friendly
way.
Managing VigorSwitch P1100 through Ethernet Port
Before start using the switch, the IP address setting of the switch should be done, then
perform the following steps:
1. Set up a physical path between the configured the switch and a PC by a qualified UTP
Cat. 5 cable with RJ-45 connector.
Note: If PC directly connects to the switch, you have to setup the same subnet mask
between them. But, subnet mask may be different for the PC in the remote site.
Please refer to the above figure about the 24-Port GbE Web Smart Switch default IP
address information.
2. Run web browser and follow the menu. Please refer to Chapter 3.

For IP address configuration, there are three parameters needed to be filled in. They are IP
address, Subnet Mask, Default Gateway and DNS.
IP address:
The address of the network device in the network is used for internetworking
communication. Its address structure looks is shown below. It is “classful” because it is
split into predefined address classes or categories.
Each class has its own network range between the network identifier and host identifier in
the 32 bits address. Each IP address comprises two parts: network identifier (address) and
host identifier (address). The former indicates the network where the addressed host resides,
and the latter indicates the individual host in the network which the address of host refers to.
And the host identifier must be unique in the same LAN. Here the term of IP address we
used is version 4, known as IPv4.
Network identifier Host identifier
32 bits
With the classful addressing, it divides IP address into three classes, class A, class B and
class C. The rest of IP addresses are for multicast and broadcast. The bit length of the
network prefix is the same as that of the subnet mask and is denoted as IP address/X, for
example, 192.168.1.0/24. Each class has its address range described below.
Class A:
Address is less than 126.255.255.255. There are a total of 126 networks can be defined
because the address 0.0.0.0 is reserved for default route and 127.0.0.0/8 is reserved for
loopback function.
Class B:
VigorSwitch P1100 User’s Guide
10
IP address range between 128.0.0.0 and 191.255.255.255. Each class B network has a
16-bit network prefix followed 16-bit host address. There are 16,384 (2^14)/16 networks
able to be defined with a maximum of 65534 (2^16 –2) hosts per network.
Class C:
IP address range between 192.0.0.0 and 223.255.255.255. Each class C network has a
24-bit network prefix followed 8-bit host address. There are 2,097,152 (2^21)/24 networks
able to be defined with a maximum of 254 (2^8 –2) hosts per network.
Class D and E:
Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP
Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used
for IP broadcast.
According to IANA (Internet Assigned Numbers Authority), there are three specific IP
address blocks reserved and able to be used for extending internal network. We call it
Private IP address and list below:
Class A 10.0.0.0 --- 10.255.255.255
Class B 172.16.0.0 --- 172.31.255.255
Class C 192.168.0.0 --- 192.168.255.255
Please refer to RFC 1597 and RFC 1466 for more information.
Subnet mask:
It means the sub-division of a class-based network or a CIDR block. The subnet is used to
determine how to split an IP address to the network prefix and the host address in bitwise
basis. It is designed to utilize IP address more efficiently and ease to manage IP network.
For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in
which the first two bytes is with all 1s. This means more than 60 thousands of nodes in flat
IP address will be at the same network. It’s too large to manage practically. Now if we
divide it into smaller network by extending network prefix from 16 bits to, say 24 bits,
that’s using its third byte to subnet this class B network. Now it has a subnet mask
255.255.255.0, in which each bit of the first three bytes is 1. It’s now clear that the first two
bytes is used to identify the class B network, the third byte is used to identify the subnet
within this class B network and, of course, the last byte is the host number.
Not all IP address is available in the sub-netted network. Two special addresses are
reserved. They are the addresses with all zero’s and all one’s host number. For example, an
IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean the
network itself, and all 1s mean IP broadcast.

In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains
126 members in the sub-netted network. Another is that the length of network prefix equals
the number of the bit with 1s in that subnet mask. With this, you can easily count the
number of IP addresses matched. The following table shows the result.
Prefix Length No. of IP matched No. of Addressable IP

/16 65536 65534
According to the scheme above, a subnet mask 255.255.255.0 will partition a network with
the class C. It means there will have a maximum of 254 effective nodes existed in this
sub-netted network and is considered a physical network in an autonomous network. So it
owns a network IP address which may looks like 168.1.2.0.
With the subnet mask, a bigger network can be cut into small pieces of network. If we want
to have more than two independent networks in a worknet, a partition to the network must
be performed. In this case, subnet mask must be applied.
For different network applications, the subnet mask may look like 255.255.255.240. This
means it is a small network accommodating a maximum of 15 nodes in the network.

Default gateway:
For the routed packet, if the destination is not in the routing table, all the traffic is put into
the device with the designated IP address, known as default router. Basically, it is a routing
policy. The gateway setting is used for Trap Events Host only in the switch.
For assigning an IP address to the switch, you just have to check what the IP address of the
network will be connected with the switch. Use the same network address and append your
host address to it.
First, IP Address: as shown above, enter “192.168.1.224”, for instance. For sure, an IP
address such as 192.168.1.x must be set on your PC.
Second, Subnet Mask: as shown above, enter “255.255.255.0”. Any subnet mask such as
255.255.255.x is allowable in this case.
Note
: The DHCP Setting is enabled in default.

Ethernet originated and was implemented at Xerox in Palo Alto, CA in 1973 and was
successfully commercialized by Digital Equipment Corporation (DEC), Intel and Xerox
(DIX) in 1980. In 1992, Grand Junction Networks unveiled a new high speed Ethernet with
the same characteristic of the original Ethernet but operated at 100Mbps, called Fast
Ethernet now. This means Fast Ethernet inherits the same frame format, CSMA/CD,
software interface. In 1998, Gigabit Ethernet was rolled out and provided 1000Mbps. Now
10G/s Ethernet is under approving. Although these Ethernet have different speed, they still
use the same basic functions. So they are compatible in software and can connect each
other almost without limitation. The transmission media may be the only problem.
In the above figure, we can see that Ethernet locates at the Data Link layer and Physical
layer and comprises three portions, including logical link control (LLC), media access
control (MAC), and physical layer. The first two comprises Data link layer, which
performs splitting data into frame for transmitting, receiving acknowledge frame, error
checking and re-transmitting when not received correctly as well as provides an error-free
channel upward to network layer.

This above diagram shows the Ethernet architecture, LLC sub-layer and MAC sub-layer,
which are responded to the Data Link layer, and transceivers, which are responded to the
Physical layer in OSI model. In this section, we are mainly describing the MAC sub-layer.

Data link layer is composed of both the sub-layers of MAC and MAC-client. Here MAC
client may be logical link control or bridge relay entity.
Logical link control supports the interface between the Ethernet MAC and upper layers in
the protocol stack, usually Network layer, which is nothing to do with the nature of the
LAN. So it can operate over other different LAN technology such as Token Ring, FDDI
and so on. Likewise, for the interface to the MAC layer, LLC defines the services with the
interface independent of the medium access technology and with some of the nature of the
medium itself.
The table above is the format of LLC PDU. It comprises four fields, DSAP, SSAP, Control
and Information. The DSAP address field identifies the one or more service access points,
in which the I/G bit indicates it is individual or group address. If all bit of DSAP is 1s, it’s a
global address. The SSAP address field identifies the specific services indicated by C/R bit
VigorSwitch P1100 User’s Guide
17
(command or response). The DSAP and SSAP pair with some reserved values indicates
some well-known services listed in the table below.
LLC type 1 connectionless service, LLC type 2 connection-oriented service and LLC type
3 acknowledge connectionless service are three types of LLC frame for all classes of
service. In Fig 3-2, it shows the format of Service Access Point (SAP). Please refer to
IEEE802.2 for more details.

Because LAN is composed of many nodes, for the data exchanged among these nodes,
each node must have its own unique address to identify who should send the data or should
receive the data. In OSI model, each layer provides its own mean to identify the unique
address in some form, for example, IP address in network layer.
VigorSwitch P1100 User’s Guide
18
The MAC is belonged to Data Link Layer (Layer 2), the address is defined to be a 48-bit
long and locally unique address. Since this type of address is applied only to the Ethernet
LAN media access control (MAC), they are referred to as MAC addresses.
The first three bytes are Organizational Unique Identifier (OUI) code assigned by IEEE.
The last three bytes are the serial number assigned by the vendor of the network device. All
these six bytes are stored in a non-volatile memory in the device. Their format is as the
following table and normally written in the form as aa-bb-cc-dd-ee-ff, a 12 hexadecimal
digits separated by hyphens, in which the aa-bb-cc is the OUI code and the dd-ee-ff is the
serial number assigned by manufacturer.

The first bit of the first byte in the Destination address (DA) determines the address to be a
Unicast (0) or Multicast frame (1), known as I/G bit indicating individual (0) or group (1).
So the 48-bit address space is divided into two portions, Unicast and Multicast. The second
bit is for global-unique (0) or locally-unique address. The former is assigned by the device
manufacturer, and the later is usually assigned by the administrator. In practice,
global-unique addresses are always applied.
A unicast address is identified with a single network interface. With this nature of MAC
address, a frame transmitted can exactly be received by the target an interface the
destination MAC points to.
A multicast address is identified with a group of network devices or network interfaces. In
Ethernet, a many-to-many connectivity in the LANs is provided. It provides a mean to send
a frame to many network devices at a time. When all bit of DA is 1s, it is a broadcast,
which means all network device except the sender itself can receive the frame and
response.

There are two major forms of Ethernet frame, type encapsulation and length encapsulation,
both of which are categorized as four frame formats 802.3/802.2 SNAP, 802.3/802.2,
Ethernet II and Netware 802.3 RAW. We will introduce the basic Ethernet frame format
defined by the IEEE 802.3 standard required for all MAC implementations. It contains
seven fields explained below.
PRE SFD DA SA Type/Length Data Pad bit if any FCS
7 7 6 6 2 46-1500 4
Preamble (PRE) - The PRE is 7-byte long with alternating pattern of ones and zeros used
to tell the receiving node that a frame is coming, and to synchronize the physical receiver
with the incoming bit stream. The preamble pattern is:
10101010 10101010 10101010 10101010 10101010 10101010 10101010
Start-of-frame delimiter (SFD) - The SFD is one-byte long with alternating pattern of
ones and zeros, ending with two consecutive 1-bits. It immediately follows the preamble
and uses the last two consecutive 1s bit to indicate that the next bit is the start of the data
packet and the left-most bit in the left-most byte of the destination address. The SFD
pattern is 10101011.
Destination address (DA) - The DA field is used to identify which network device(s)
should receive the packet. It is a unique address. Please see the section of MAC addressing.
VigorSwitch P1100 User’s Guide
19
Source addresses (SA) - The SA field indicates the source node. The SA is always an
individual address and the left-most bit in the SA field is always 0.
Length/Type - This field indicates either the number of the data bytes contained in the data
field of the frame, or the Ethernet type of data. If the value of first two bytes is less than or
equal to 1500 in decimal, the number of bytes in the data field is equal to the Length/Type
value, i.e. this field acts as Length indicator at this moment. When this field acts as Length,
the frame has optional fields for 802.3/802.2 SNAP encapsulation, 802.3/802.2
encapsulation and Netware 802.3 RAW encapsulation. Each of them has different fields
following the Length field.
If the Length/Type value is greater than 1500, it means the Length/Type acts as Type.
Different type value means the frames with different protocols running over Ethernet being
sent or received.
For example,
0x0800 IP datagram
0x0806 ARP
0x0835 RARP
0x8137 IPX datagram
0x86DD IPv6
Data - Less than or equal to 1500 bytes and greater or equal to 46 bytes. If data is less than
46 bytes, the MAC will automatically extend the padding bits and have the payload be
equal to 46 bytes. The length of data field must equal the value of the Length field when
the Length/Type acts as Length.
Frame check sequence (FCS) - This field contains a 32-bit cyclic redundancy check
(CRC) value, and is a check sum computed with DA, SA, through the end of the data field
with the following polynomial.
It is created by the sending MAC and recalculated by the receiving MAC to check if the
packet is damaged or not.

The MAC sub-layer has two primary jobs to do:
1. Receiving and transmitting data. When receiving data, it parses frame to detect error;
when transmitting data, it performs frame assembly.
2. Performing Media access control. It prepares the initiation jobs for a frame
transmission and makes recovery from transmission failure.

As Ethernet adopted Carrier Sense Multiple Access with Collision Detect (CSMA/CD), it
detects if there is any carrier signal from another network device running over the physical
medium when a frame is ready for transmission. This is referred to as sensing carrier, also
“Listen”. If there is signal on the medium, the MAC defers the traffic to avoid a
transmission collision and waits for a random period of time, called backoff time, then
sends the traffic again.
After the frame is assembled, when transmitting the frame, the preamble (PRE) bytes are
inserted and sent first, then the next, Start of frame Delimiter (SFD), DA, SA and through
VigorSwitch P1100 User’s Guide
20
the data field and FCS field in turn. The followings summarize what a MAC does before
transmitting a frame.
1. MAC will assemble the frame. First, the preamble and Start-of-Frame delimiter will be
put in the fields of PRE and SFD, followed DA, SA, tag ID if tagged VLAN is applied,
Ethertype or the value of the data length, and payload data field, and finally put the
FCS data in order into the responded fields.
2. Listen if there is any traffic running over the medium. If yes, wait.
3. If the medium is quiet, and no longer senses any carrier, the MAC waits for a period of
time, i.e. inter-frame gap time to have the MAC ready with enough time and then start
transmitting the frame.
4. During the transmission, MAC keeps monitoring the status of the medium. If no
collision happens until the end of the frame, it transmits successfully. If there is a
collision happened, the MAC will send the patterned jamming bit to guarantee the
collision event propagated to all involved network devices, then wait for a random
period of time, i.e. backoff time. When backoff time expires, the MAC goes back to the
beginning state and attempts to transmit again. After a collision happens, MAC
increases the transmission attempts. If the count of the transmission attempt reaches 16
times, the frame in MAC’s queue will be discarded.
Ethernet MAC transmits frames in half-duplex and full-duplex ways. In halfduplex
operation mode, the MAC can either transmit or receive frame at a moment, but cannot do
both jobs at the same time.
As the transmission of a MAC frame with the half-duplex operation exists only in the same
collision domain, the carrier signal needs to spend time to travel to reach the targeted
device. For two most-distant devices in the same collision domain, when one sends the
frame first, and the second sends the frame, in worstcase, just before the frame from the
first device arrives. The collision happens and will be detected by the second device
immediately. Because of the medium delay, this corrupted signal needs to spend some time
to propagate back to the first device. The maximum time to detect a collision is
approximately twice the signal propagation time between the two most-distant devices.
This maximum time is traded-off by the collision recovery time and the diameter of the
LAN.
In the original 802.3 specification, Ethernet operates in half duplex only. Under this
condition, when in 10Mbps LAN, it’s 2500 meters, in 100Mbps LAN, it’s approximately
200 meters and in 1000Mbps, 200 meters. According to the theory, it should be 20 meters.
But it’s not practical, so the LAN diameter is kept by using to increase the minimum frame
size with a variable-length non-data extension bit field which is removed at the receiving
MAC. The following tables are the frame format suitable for 10M, 100M and 1000M
Ethernet, and some parameter values that shall be applied to all of these three types of
Ethernet.
Actually, the practice Gigabit Ethernet chips do not feature this so far. They all have their
chips supported full-duplex mode only, as well as all network vendors’ devices. So this
criterion should not exist at the present time and in the future. The switch’s Gigabit module
supports only full-duplex mode.

In full-duplex operation mode, both transmitting and receiving frames are processed
simultaneously. This doubles the total bandwidth. Full duplex is much easier than half
duplex because it does not involve media contention, collision, retransmission schedule,
padding bits for short frame. The rest functions follow the specification of IEEE802.3. For
example, it must meet the requirement of minimum inter-frame gap between successive
frames and frame format the same as that in the half-duplex operation.
Because no collision will happen in full-duplex operation, for sure, there is no mechanism
to tell all the involved devices. What will it be if receiving device is busy and a frame is
coming at the same time? Can it use “backpressure” to tell the source device? A function
flow control is introduced in the full-duplex operation.

Flow control is a mechanism to tell the source device stopping sending frame for a
specified period of time designated by target device until the PAUSE time expires. This is
accomplished by sending a PAUSE frame from target device to source device. When the
target is not busy and the PAUSE time is expired, it will send another PAUSE frame with
zero time-to-wait to source device. After the source device receives the PAUSE frame, it
will again transmit frames immediately. PAUSE frame is identical in the form of the MAC
frame with a pause-time value and with a special destination MAC address
01-80-C2-00-00-01. As per the specification, PAUSE operation can not be used to inhibit
the transmission of MAC control frame.
Normally, in 10Mbps and 100Mbps Ethernet, only symmetric flow control is supported.
However, some switches (e.g. 24-Port GbE Web Smart Switch) support not only
symmetric but asymmetric flow controls for the special application. In Gigabit Ethernet,
both symmetric flow control and asymmetric flow control are supported. Asymmetric flow
control only allows transmitting PAUSE frame in one way from one side, the other side is
not but receipt-and-discard the flow control information. Symmetric flow control allows
both two ports to transmit PASUE frames each other simultaneously.

After the end of a transmission, if a network node is ready to transmit data out and if there
is no carrier signal on the medium at that time, the device will wait for a period of time
known as an inter-frame gap time to have the medium clear and stabilized as well as to
have the jobs ready, such as adjusting buffer counter, updating counter and so on, in the
receiver site. Once the inter-frame gap time expires after the de-assertion of carrier sense,
the MAC transmits data. In IEEE802.3 specification, this is 96-bit time or more.

Collision happens only in half-duplex operation. When two or more network nodes
transmit frames at approximately the same time, a collision always occurs and interferes
with each other. This results the carrier signal distorted and undiscriminated. MAC can
afford detecting, through the physical layer, the distortion of the carrier signal. When a
collision is detected during a frame transmission, the transmission will not stop
immediately but, instead, continues transmitting until the rest bits specified by jamSize are
completely transmitted. This guarantees the duration of collision is enough to have all
involved devices able to detect the collision. This is referred to as Jamming. After jamming
pattern is sent, MAC stops transmitting the rest data queued in the buffer and waits for a
random period of time, known as backoff time with the following formula. When backoff
time expires, the device goes back to the state of attempting to transmit frame. The backoff
time is determined by the formula below. When the times of collision is increased, the
backoff time is getting long until the collision times excess 16. If this happens, the frame
will be discarded and backoff time will also be reset.

In essence, the frame reception is the same in both operations of half duplex and full
duplex, except that full-duplex operation uses two buffers to transmit and receive the frame
independently. The receiving node always “listens” if there is traffic running over the
medium when it is not receiving a frame. When a frame destined for the target device
comes, the receiver of the target device begins receiving the bit stream, and looks for the
PRE (Preamble) pattern and Start-of-Frame Delimiter (SFD) that indicates the next bit is
the starting point of the MAC frame until all bit of the frame is received.
For a received frame, the MAC will check:
1. If it is less than one slotTime in length, i.e. short packet, and if yes, it will be discarded
by MAC because, by definition, the valid frame must be longer than the slotTime. If
the length of the frame is less than one slotTime, it means there may be a collision
happened somewhere or an interface malfunctioned in the LAN. When detecting the
case, the MAC drops the packet and goes back to the ready state.
2. If the DA of the received frame exactly matches the physical address that the receiving
MAC owns or the multicast address designated to recognize. If not, discards it and the
MAC passes the frame to its client and goes back to the ready state.
3. If the frame is too long. If yes, throws it away and reports frame Too Long.
4. If the FCS of the received frame is valid. If not, for 10M and 100M Ethernet, discards
the frame. For Gigabit Ethernet or higher speed Ethernet, MAC has to check one more
field, i.e. extra bit field, if FCS is invalid. If there is any extra bits existed, which must
meet the specification of IEEE802.3. When both FCS and extra bits are valid, the
received frame will be accepted, otherwise discards the received frame and reports
frameCheckError if no extra bits appended or alignmentError if extra bits appended.
5. If the length/type is valid. If not, discards the packet and reports lengthError.
6. If all five procedures above are ok, then the MAC treats the frame as good and
de-assembles the frame.

VLAN tagging is a 4-byte long data immediately following the MAC source address.
When tagged VLAN is applied, the Ethernet frame structure will have a little change
shown as follows.
Only two fields, VLAN ID and Tag control information are different in comparison with
the basic Ethernet frame. The rest fields are the same.
The first two bytes is VLAN type ID with the value of 0x8100 indicating the received
frame is tagged VLAN and the next two bytes are Tag Control Information (TCI) used to
provide user priority and VLAN ID, which are explained respectively in the following
table.

Bits 11-0
VID (VLAN Identifier)
0x000: Null VID. No VID is present and only user priority is
present.
0x001: Default VID
0xFFF: Reserved
Note: RIF is used in Token Ring network to provide source routing and
comprises two fields, Routing Control and Route Descriptor.
When MAC parses the received frame and finds a reserved special value 0x8100 at the
location of the Length/Type field of the normal non-VLAN frame, it will interpret the
received frame as a tagged VLAN frame. If this happens in a switch, the MAC will forward
it, according to its priority and egress rule, to all the ports that is associated with that VID.
If it happens in a network interface card, MAC will deprive of the tag header and process it
in the same way as a basic normal frame. For a VLAN-enabled LAN, all involved devices
must be equipped with VLAN optional function.
At operating speeds above 100 Mbps, the slotTime employed at slower speeds is
inadequate to accommodate network topologies of the desired physical extent. Carrier
Extension provides a means by which the slotTime can be increased to a sufficient value
for the desired topologies, without increasing the minFrameSize parameter, as this would
have deleterious effects. Nondata bits, referred to as extension bits, are appended to frames
that are less than slotTime bits in length so that the resulting transmission is at least one
slotTime in duration. Carrier Extension can be performed only if the underlying physical
layer is capable of sending and receiving symbols that are readily distinguished from data
symbols, as is the case in most physical layers that use a block encoding/decoding scheme.
The maximum length of the extension is equal to the quantity (slotTime - minFrameSize).
The MAC continues to monitor the medium for collisions while it is transmitting extension
bits, and it will treat any collision that occurs after the threshold (slotTime) as a late
collision.

This chapter would introduce how to manage your Web Smart Switch and how to
configure the 10/100/1000Mbps TP Ports on the switch via web user interfaces. Web Smart
Switch provides 24 fixed Gigabit Ethernet TP ports. With this facility, you can easily
access and monitor the status like MIBs, port activity, and multicast traffic through any
ports on the switch.
The default values of the Switch are listed in the figure below:
When the configuration of your Web Smart Switch is finished, you can browse it by the IP
address you set up. For instance, uncheck the Enable box of DHCP Setting first (it is
enabled in default). Next, type http://192.168.1. in the address row in a browser, then the
following screen would show up and ask for your password input for login and access
authentication. The default password is “admin”. For the first time access, please enter the
default password, and click <Apply> button. The login process now would be completed.
Web Smart Switch supports a simplified user management function which allows only one
administrator to configure the switch at one time.
To optimize the display effect, we recommend Microsoft IE and 1024x768 display
resolution.

After login, System Information would be displayed as the following illustration. This page
lists default values and shows you the basic information of the switch, including “Model”,
System Name”, “System Location”, “System Contact”, “MAC Address”, “IPv4 Address”,
“IPv6 Address”, “System Uptime”, “Current Time”, “Loader Version”, “Loader Date”,
“Firmware Version”, “Firmware Date”, “ Telnet”, “HTTP”, “HTTPS” and “SNMP”. With
this information, you will know the software version, MAC address, ports available and so
on. It would be helpful while malfunction occurred.
On the top part of the information page, it shows the front panel of the switch. Linked ports
will be displayed in green color, and linked-off ones will be in black. For the optional
modules, the slots with no module will only show covered plates, the other slots with
installed modules would present modules. The images of modules would depend on the
ones you insert. Vice versa, if ports are disconnected, they will show just in black.
On the left side, the main menu tree for web is listed in the page. The functions of each
folder are described in its corresponded section respectively. As to the function names in
normal type are the sub-functions. When clicking it, the function is performed.

Description
Type a brief description for such entry.
State Port admin state.
Enabled: Check the box to enable the port.
Disabled: Uncheck the box to disable the port.
Speed
Port speed capabilities:
Auto: Auto speed with all capabilities.

100M: Force speed with 100M ability.
1000M: Force speed with 1000M ability.
Selecting Auto (auto-negotiation) allows one port to
negotiate with a peer port automatically to obtain the
connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, a port on the
switch negotiates with the peer automatically to
determine the connection speed and duplex mode. If the
peer port does not support auto-negotiation or turns off
this feature, the switch determines the connection speed
by detecting the signal on the cable and using half duplex
mode. When the switch’s auto-negotiation is turned off, a
port uses the pre-configured speed and duplex mode
when making a connection, thus requiring you to make
sure that the settings of the peer port are the same in order
to connect.
VigorSwitch P1100 User’s Guide
42
Duplex
Port duplex capabilities:
Auto: Auto duplex with all capabilities.
Half: Auto speed with 10/100M ability only.
Full: Auto speed with 10/100/1000M ability only.
Flow Control
A concentration of traffic on a port decreases port
bandwidth and overflows buffer memory causing packet
discards and frame losses. Flow Control is used to
regulate transmission of signals to match the bandwidth
of the receiving port. The switch uses IEEE802.3x flow
control in full duplex mode and backpressure flow
control in half duplex mode. IEEE802.3x flow control is
used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending
signals when the receiving port memory buffers fill. Back
Pressure flow control is typically used in half duplex
mode to send a "collision" signal to the sending port
(mimicking a state of packet collision) causing the
sending port to temporarily stop sending signals and
resend later.
Select “Auto”/ “Enable” to enable it. Or select
“Disable” to disable it.

Speed
Port speed capabilities:
Auto: Auto speed with all capabilities.
Auto-10M: Auto speed with 10M ability only.
Auto-100M: Auto speed with 100M ability only.
Auto-1000M: Auto speed with 1000M ability only.

Selecting Auto (auto-negotiation) allows one port to
negotiate with a peer port automatically to obtain the
connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, a port on the
switch negotiates with the peer automatically to
determine the connection speed and duplex mode. If the
peer port does not support auto-negotiation or turns off
this feature, the switch determines the connection speed
by detecting the signal on the cable and using half duplex
mode. When the switch’s auto-negotiation is turned off, a
port uses the pre-configured speed and duplex mode
when making a connection, thus requiring you to make
sure that the settings of the peer port are the same in order
to connect.
Flow Control
A concentration of traffic on a port decreases port
bandwidth and overflows buffer memory causing packet
VigorSwitch P1100 User’s Guide

discards and frame losses. Flow Control is used to
regulate transmission of signals to match the bandwidth
of the receiving port. The switch uses IEEE802.3x flow
control in full duplex mode and backpressure flow
control in half duplex mode. IEEE802.3x flow control is
used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending
signals when the receiving port memory buffers fill. Back
Pressure flow control is typically used in half duplex
mode to send a "collision" signal to the sending port
(mimicking a state of packet collision) causing the
sending port to temporarily stop sending signals and
resend later.
Select “Auto”/ “Enable” to enable it. Or select
“Disable” to disable it.

A virtual local area network, virtual LAN or VLAN, is a group of hosts with a common set
of requirements that communicate as if they were attached to the same broadcast domain,
regardless of their physical location. A VLAN has the same attributes as a physical local
area network (LAN), but it allows for end stations to be grouped together even if they are
not located on the same network switch. VLAN membership can be configured through
software instead of physically relocating devices or connections.

Enable: Check the box to force to true state (as link to a
host)
Disable: Uncheck the box to force to false state (as link
to a host).
In the edge mode, the interface would be put into the
Forwarding state immediately upon link up. If the edge
mode is enabled for the interface and there are BPDUs
received on the interface, the loop might be occurred in
the short time before the STP state change.

Switching>>Spanning Tree>> Statistics
Function description:
To display STP statistics.
Bridge Protocol Data Units (BPDUs) are frames that contain information about the
Spanning tree protocol (STP). Switches send BPDUs using a unique MAC address from its
origin port and a multicast address as destination MAC (01:80:C2:00:00:00, or
01:00:0C:CC:CC:CD for Per VLAN Spanning Tree). For STP algorithms to function, the
switches need to share information about themselves and their connections. What they
share are bridge protocol data units (BPDUs). BPDUs are sent out as multicast frames to
which only other layer 2 switches or bridges are listening. If any loops (multiple possible
paths between switches) are found in the network topology, the switches will co-operate to
disable a port or ports to ensure that there are no loops; that is, from one device to any other
device in the layer 2 network, only one path can be taken.

A Denial of Service (DoS) attack is a hacker attempt to make a device unavailable to its
users. DoS attacks saturate the device with external communication requests, so that it
cannot respond to legitimate traffic. These attacks usually lead to a device CPU overload.
The DoS protection feature is a set of predefined rules that protect the network from
malicious attacks. The DoS Security Suite Setting enables activating the security suite.

Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for
managing devices on IP networks". Devices that typically support SNMP include routers,
switches, servers, workstations, printers, modem racks and more.
SNMP is used mostly in network management systems to monitor network-attached
devices for conditions that warrant administrative attention.
SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering
Task Force (IETF). It consists of a set of standards for network management, including an
application layer protocol, a database schema, and a set of data objects.
An SNMP-managed network consists of three key components:
VigorSwitch P1100 User’s Guide
108
Managed device
Agent - software which runs on managed devices
Network management station (NMS) - software which runs on the manager
A managed device is a network node that implements an SNMP interface that allows
unidirectional (read-only) or bidirectional (read and write) access to node-specific
information. Managed devices exchange node-specific information with the NMSs.
Sometimes called network elements, the managed devices can be any type of device,
including, but not limited to, routers, access servers, switches, bridges, hubs, IP telephones,
IP video cameras, computer hosts, and printers.
An agent is a network-management software module that resides on a managed device. An
agent has local knowledge of management information and translates that information to or
from an SNMP-specific form.
A network management station (NMS) executes applications that monitor and control
managed devices. NMSs provide the bulk of the processing and memory resources required
for network management. One or more NMSs may exist on any managed network.
