SSNNMMPP//RRMMOONN
SNMP agent and RMON MIB. In the device, SNMP agent is a client software which is
operating over SNMP protocol used to receive the command from SNMP manager (server
site) and echo the corresponded data, i.e. MIB object. Besides, SNMP agent will actively
issue TRAP information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the SNMP
MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB (RFC
1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet MIB (RFC 1643)
and so on.
IIGGMMPP SSnnooooppiinngg
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used to establish the
multicast groups to forward the multicast packet to the member ports, and, in nature, avoid
wasting the bandwidth while IP multicast packets are running over the network.
IIGGMMPP PPrrooxxyy
The implementation of IP multicast processing. The switch supports IGMP version 1 and
IGMP version 2, efficient use of network bandwidth, and fast response time for channel
changing. IGMP version 1 (IGMPv1) is described in RFC1112 ,and IGMP version 2
(IGMPv2) is described in RFC 2236. Hosts interact with the system through the exchange
of IGMP messages. Similarly, when you configure IGMP proxy, the system interacts with
the router on its upstream interface through the exchange of IGMP messages. However,
when acting as the proxy, the system performs the host portion of the IGMP task on the
upstream interface as follows:
¾ When queried, sends group membership reports to the group.
Page 9
VigorSwitch G2240 User’s Guide
3
¾ When one of its hosts joins a multicast address group to which none of its other hosts
belong, sends unsolicited group membership reports to that group.
¾ When the last of its hosts in a particular multicast group leaves the group, sends an
unsolicited leave group membership report to the all-routers group (244.0.0.2).

It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically,
there are two categories of fiber, multi mode (MM) and single mode (SM). The later is
categorized into several classes by the distance it supports. They are SX, LX, LHX, XD,
and ZX. From the viewpoint of connector type, there mainly are LC and BIDI LC.
¾ Gigabit Fiber with multi-mode LC SFP module
¾ Gigabit Fiber with single-mode LC SFP module

Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch cascading
that you may up-link the switches unlimitedly. In practice, the network extension
(cascading levels & overall diameter) must follow the constraint of the IEEE
802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations
are the timing requirement from physical signals defined by 802.3 series specification of
Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such
as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber 100Base-TX TP/100Base-FX Fiber
Round trip Delay: 4096 Round trip Delay: 512
Cat. 5 TP Wire: 11.12/m
Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m
Page 15
VigorSwitch G2240 User’s Guide

Fiber Cable: 10.10/m TP to fiber Converter: 56
Bit Time unit: 1ns (1sec./1000 Mega bit)
Bit Time unit: 0.01μs (1sec./100 Mega bit)
Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be
within Round Trip Delay (bit times) in a half-duplex network segment (collision domain).
For full-duplex operation, this will not be applied. You may use the TP-Fiber module to
extend the TP node distance over fiber optic and provide the long haul connection.
Typical Network Topology in Deployment
A hierarchical network with minimum levels of switch may reduce the timing delay
between server and client station. Basically, with this approach, it will minimize the
number of switches in any one path; will lower the possibility of network loop and will
improve network efficiency. If more than two switches are connected in the same network,
select one switch as Level 1 switch and connect all other switches to it at Level 2.
Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN
or other special requirements are applied.
Case 1: All switch ports are in the same local area network.
Every port can access each other.
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.
Page 16
VigorSwitch G2240 User’s Guide
10
Case 2: Port-based VLAN -1
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 access
VLAN4 members.
VLAN3 members could not access VLAN1, VLAN2 and VLAN4.
VLAN4 members could not access VLAN1 and VLAN3 members, but they could
access VLAN2 members.

We offer you three ways to startup the switch management function. They are RS-232
console, CLI, and Web. Users can use any one of them to monitor and configure the switch.
You can touch them through the following procedures.
¾ Configuring the Management Agent of VigorSwitch G2240 through the Serial
RS-232 Port
¾ Configuring the Management Agent of VigorSwitch G2240 through the Ethernet Port
Note: Please first modify the IP address, Subnet mask, Default gateway and DNS
through RS-232 console, and then do the next.
Configuring the Management Agent of VigorSwitch G2240 through the Serial RS-232
Port
To perform the configuration through RS-232 console port, the switch’s serial port must be
directly connected to a DCE device, for example, a PC, through RS-232 cable with DB-9
connector. Next, run a terminal emulator with the default setting of the switch’s serial port.
With this, you can communicate with the switch.
In the switch, RS-232 interface only supports baud rate 57.6k bps with 8 data bits, 1 stop
bit, no parity check and no flow control.
RS-232 cable with female DB-9 connector at both ends
VigorSwitch G2240
Default IP Setting:
IP address = DHCP Enabled
Subnet Mask = DHCP Enabled
Default Gateway = DHCP Enabled
To configure the switch, please follow the procedures below:
1. Find the RS-232 DB-9 cable with female DB-9 connector bundled. Normally, it just
uses pins 2, 3 and 7. See also Appendix B for more details on Null Modem Cable
Specifications.
2. Attaches the DB-9 female cable connector to the male serial RS-232 DB-9 connector
on the switch.
3. Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial port, running a
terminal emulator supporting VT100/ANSI terminal with the switch’s serial port
default settings. For example, Windows98/2000/XP HyperTerminal utility.
Note: The switch’s serial port default settings are listed as follows:
Baud rate 115200
Stop bits 1
RS-232
Page 19
VigorSwitch G2240 User’s Guide

Data bits 8
Parity N
Flow control none
4. When you complete the connection, then press <Enter> key. The login prompt will be
shown on the screen. The default username and password are shown as below:
Username = admin Password = admin
Additionally, if a user connects VigorSwitch to VigorPro router, he also can access into
VigorPro web configuration page to find out External Devices menu item. Then click the
new added switch icon to open the web configuration of VigorSwitch.
Set IP Address, Subnet Mask and Default Gateway IP Address
You can first either configure your PC IP address or change IP address of the switch, next
to change the IP address of default gateway and subnet mask.
For example, your network address is 10.1.1.0, and subnet mask is 255.255.255.0. You can
change the switch’s default IP address 192.168.1.1 to 10.1.1.1 and set the subnet mask to
be 255.255.255.0. Then, choose your default gateway, may be it is 10.1.1.254.
Default Value VigorSwitch G2240 Your Network Setting
IP Address 192.168.1.1 10.1.1.1
Subnet 255.255.255.0 255.255.255.0
Default Gateway 192.168.1.254 10.1.1.254
After completing these settings in the switch, it will reboot to have the configuration taken
effect. After this step, you can operate the management through the network, no matter it is
from a web browser or Network Management System (NMS).

Configuring the Management Agent of VigorSwitch G2240 through the Ethernet Port
There are three ways to configure and monitor the switch through the switch’s Ethernet
port. They are CLI, Web browser and SNMP manager. The user interface for the last one is
NMS dependent and does not cover here. We just introduce the first two types of
management interface.
Managing VigorSwitch G2240 through Ethernet Port
Before you communicate with the switch, you have to finish the
configuration of the IP address or to know the IP address of the switch. Then, follow the
procedures listed below.
Page 21
VigorSwitch G2240 User’s Guide
15
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.
2. Run CLI or web browser and follow the menu. Please refer to Chapter 2.

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
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:
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.
32 bits
Page 23
VigorSwitch G2240 User’s Guide
17
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.
Page 24
VigorSwitch G2240 User’s Guide
18
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
/32 1 /31 2 /30 4 2
/29 8 6
/28 16 14
/27 32 30
/26 64 62
/25 128 126
/24 256 254
/23 512 510
/22 1024 1022
/21 2048 2046
/20 4096 4094
/19 8192 8190
/18 16384 16382
/17 32768 32766
/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.
Page 25
VigorSwitch G2240 User’s Guide
19
First, IP Address: as shown above, enter “192.168.1.1”, 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.
DNS:
The Domain Name Server translates human readable machine name to IP address. Every
machine on the Internet has a unique IP address. A server generally has a static IP address.
To connect to a server, the client needs to know the IP of the server. However, user
generally uses the name to connect to the server. Thus, the switch DNS client program
(such as a browser) will ask the DNS to resolve the IP address of the named server.

This chapter instructs you how to configure and manage the switch through the web user
interface it supports, to access and manage the 22-Port 10/100Mbps TP and 2-Port Gigabit
TP/SFP Fiber management Ethernet switch. With this facility, you can easily access and
monitor through any one port of the switch all the status of the switch, including MIBs
status, each port activity, Spanning tree status, port aggregation status, multicast traffic,
VLAN and priority status, even illegal access record and so on.
The default values of the managed switch are listed in the table below:
IP Address
DHCP Enabled
Subnet Mask
DHCP Enabled
Default Gateway
DHCP Enabled
Username
admin
Password
admin
After the managed switch has been finished configuration in the CLI via the switch’s serial
interface, you can browse it. For example, type http://192.168.1.1
in the address row in a
browser, it will show the following screen (see Figure below) and ask you inputting
username and password in order to login and access authentication. The default username
and password are both “admin”. For the first time to use, please enter the default username
and password, then click the <Login> button. The login process now is completed.
Just click the link of “Forget Password” in WebUI or input “Ctrl+Z” in CLI’s login screen
in case the user forgets the manager’s password. Then, the system will display a serial No.
for the user. Write down this serial No. and contact your vendor, the vendor will give you a
temporary password. Use this new password as ID and Password, and it will allow the user
to login the system with manager authority temporarily. Due to the limit of this new
password, the user only can login the system one time, therefore, please modify your
password immediately after you login in the system successfully.
In this login menu, you have to input the complete username and password respectively,
the switch will not give you a shortcut to username automatically. This looks inconvenient,
but safer.
In the switch, it supports a simple user management function allowing only one
administrator to configure the system at the same time. If there are two or more users using
administrator’s identity, the switch will allow the only one who logins first to configure the
system. The rest of users, even with administrator’s identity, can only monitor the system.
For those who have no administrator’s identity, can only monitor the system. There are
only a maximum of three users able to login simultaneously in the switch.
To optimize the display effect, we recommend you use Microsoft IE 6.0 above, Netscape
V7.1 above or FireFox V1.00 above and have the resolution 1024x768. The switch
supported neutral web browser interface.

will display green; as to the ports, which are link off, they will be dark. For the optional
modules, the slot will show only a cover plate if no module exists and will show a module
if a module is present. The image of module depends on the one you inserted. The same, if
disconnected, the port will show just dark, if linked, green.
In this device, there are clicking functions on the panel provided for the information of the
ports. These are very convenient functions for browsing the information of a single port.
When clicking the port on the front panel, an information window for the port will be pop
out.
It shows the basic information of the clicked port. With this, you’ll see the information about
the port status, traffic status and bandwidth rating for egress and ingress respectively.
On the left-top corner, there is a pull-down list for Auto Logout. For the sake of security,
we provide auto-logout function to protect you from illegal user as you are leaving. If you
do not choose any selection in Auto Logout list, it means you turn on the Auto Logout
function and the system will be logged out automatically when no action on the device 3
minutes later. If OFF is chosen, the screen will keep as it is. Default is ON

The switch provides manual and automatic ways to set the system time via NTP. Manual
setting is simple and you just input “Year”, “Month”, “Day”, “Hour”, “Minute” and
“Second” within the valid value range indicated in each item. If you input an invalid value,
for example, 61 in minute, the switch will clamp the figure to 59.
NTP is a well-known protocol used to synchronize the clock of the switch system time over
a network. NTP, an internet draft standard formalized in
RFC 1305, has been adopted on the
system is version 3 protocol. The switch provides four built-in NTP server IP addresses
resided in the Internet and a user-defined NTP server IP address. The time zone is
Greenwich-centered which uses the expression form of GMT+/- xx hours.

Set the system time by manual input or set it by syncing from Time servers. The function
also supports daylight saving for different area’s time adjustment.
Parameter description:
Current Time: Show the current time of the system.
Manual: This is the function to adjust the time manually. Filling the
valid figures in the fields of Year, Month, Day, Hour,
Minute and Second respectively and press <Apply> button,
time is adjusted. The valid figures for the parameter Year,
Month, Day, Hour, Minute and Second are >=2000, 1-12,
1-31, 0-23, 0-59 and 0-59 respectively. Input the wrong
figure and press <Apply> button, the device will reject the
time adjustment request. There is no time zone setting in
Manual mode.
NTP: NTP is Network Time Protocol and is used to sync the
network time based Greenwich Mean Time (GMT). If use
the NTP mode and select a built-in NTP time server or
manually specify an user-defined NTP server as well as
Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time
automatically, NTP does not update the time periodically
without user’s processing.
Time Zone is an offset time off GMT. You have to select the
time zone first and then perform time sync via NTP because
the switch will combine this time zone offset and updated
NTP time to come out the local time, otherwise, you will not
able to get the correct time. The switch supports
configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
Daylight Saving: Daylight saving is adopted in some countries. If set, it will
adjust the time lag or in advance in unit of hours, according
Page 36

to the starting date and the ending date. For example, if you
set the day light saving to be 1 hour. When the time passes
over the starting time, the system time will be increased one
hour after one minute at the time since it passed over. And
when the time passes over the ending time, the system time
will be decreased one hour after one minute at the time since
it passed over.
The switch supports valid configurable day light saving time
is –5 ~ +5 step one hour. The zero for this parameter means
it need not have to adjust current time, equivalent to in-act
daylight saving. You don’t have to set the starting/ending
date as well. If you set daylight saving to be non-zero, you
have to set the starting/ending date as well; otherwise, the
daylight saving function will not be activated.
Default for Daylight Saving: 0.
The following parameters are configurable for the function
Daylight Saving and described in detail.
Day Light Saving Start:
This is used to set when to start performing the day light
saving time.

IP configuration is one of the most important configurations in the switch. Without the
proper setting, network manager will not be able to manage or view the device. The switch
supports both manual IP address setting and automatic IP address setting via DHCP server.
When IP address is changed, you must reboot the switch to have the setting taken effect
and use the new IP to browse for web management and CLI management.
Function name:
IP Configuration
Function description:
Set IP address, subnet mask, default gateway and DNS for the switch.
Page 37
VigorSwitch G2240 User’s Guide
31
Parameter description:
DHCP Setting: DHCP is the abbreviation of Dynamic Host Configuration
Protocol. Here DHCP means a switch to turn ON or OFF the
function.
The switch supports DHCP client used to get an IP address
automatically if you set this function “Enable”. When
enabled, the switch will issue the request to the DHCP server
resided in the network to get an IP address. If DHCP server
is down or does not exist, the switch will issue the request
and show IP address is under requesting, until the DHCP
server is up. Before getting an IP address from DHCP server,
the device will not continue booting procedures. If set this
field “Disable”, you’ll have to input IP address manually.
For more details about IP address and DHCP, please see the
Section 2-1-5 “IP Address Assignment” in this manual.
Default: Disable
IP address: Users can configure the IP settings and fill in new values if
users set the DHCP function “Disable”. Then, click
<Apply> button to update.
When DHCP is disabled, Default: 192.168.1.1
If DHCP is enabled, this field is filled by DHCP server and
will not allow user manually set it any more.
Subnet mask: Subnet mask is made for the purpose to get more network
address because any IP device in a network must own its IP
address, composed of Network address and Host address,
otherwise can’t communicate with other devices each other.
But unfortunately, the network classes A, B, and C are all
too large to fit for almost all networks, hence, subnet mask is
introduced to solve this problem. Subnet mask uses some
bits from host address and makes an IP address looked
Network address, Subnet mask number and host address. It
Page 38
VigorSwitch G2240 User’s Guide
32
is shown in the following figure. This reduces the total IP
number of a network able to support, by the amount of 2
power of the bit number of subnet number (2^(bit number of
subnet number)).
Subnet mask is used to set the subnet mask value, which
should be the same value as that of the other devices resided
in the same network it attaches.
For more information, please also see the Section 2-1-5 “IP
Address Assignment” in this manual.
Default: 255.255.255.0
Default gateway: Set an IP address for a gateway to handle those packets that
do not meet the routing rules predefined in the device. If a
packet does not meet the criteria for other pre-defined path,
it must be forwarded to a default router on a default path.
This means any packet with undefined IP address in the
routing table will be sent to this device unconditionally.
Default: 192.168.1.254
DNS Server You can set the DNS server by manual or auto when the
DHCP is enabled. Only manual setting is supported when
DHCP is disabled. The DNS server IP will be obtained from
DHCP server when you set the DNS server by auto.

Function name:
Virtual Stack
Function description:
Virtual Stack Management (VSM) is the group management function. Through the proper
configuration of this function, switches in the same LAN will be grouped automatically.
And among these switch, one switch will be a master machine, and the others in this group
will become the slave devices.
VSM offers a simple centralized management function. It is not necessary to remember the
addresses of all devices, manager is capable of managing the network with knowing the
address of the Master machine. Instead of SNMP or Telnet UI, VSM is only available in
Web UI. While one switch becomes the Master, two rows of buttons for group device will
Page 43
VigorSwitch G2240 User’s Guide
37
appear on the top of its Web UI. By pressing these buttons, user will be allowed to connect
the Web UI of the devices of the group in the same window without the login of these
devices.
The most top-left button is only for Master device. The background color of the button you
press will be changed to represent that the device is under your management.
Note: It will remove the grouping temporarily in case that you login the switch via
the console.
The device of the group will be shown as station address (the last number of IP Address) +
device name on the button (e.g. 10_VigorSw), otherwise it will show ” ---- “ if no
corresponding device exists.
Once the devices join the group successfully, then they are merely able to be managed via
Master device, and user will fail to manage them via telnet/console/web individually.
Up to 16 devices can be grouped for VSM, however, only one Master is allowed to exist in
each group. For Master redundancy, user may configure more than two devices as the
Master device. However, the Master device with the smaller MAC value will be the Master
one. All of these 16 devices can become Master device and back up with each other.
Parameter description:
State: It is used for the activation or de-activation of VSM. Default
is “Disable”.
Role: The role that the switch would like to play in virtual stack.
Two types of roles, including master and slave are offered
for option. Default is Master.
Group ID: It is the group identifier (GID) which signs for VSM.

Port Configuration is applied to change the setting of each port. In this configuration
function, you can set/reset the following functions. All of them are described in detail
below.
Function name:
Port Configuration
Function description:
It is used to set each port’s operation mode. The switch supports 3 parameters for each port.
They are state, mode and flow control.
Parameter description:
Speed: Set the speed and duplex of the port. In speed, if the media is
1Gbps fiber, it is always 1000Mbps and the duplex is full
only. If the media is TP, the Speed/Duplex is comprised of
the combination of speed mode, 10/100/1000Mbps, and
duplex mode, full duplex and half duplex. The following
table summarized the function the media supports.
Page 45

1000M TP ON/OFF 10/100/1000M Full for all, Half
for 10/100
1000M
Fiber
ON/OFF 1000M Full
In Auto-negotiation mode, no default value. In Forced mode,
default value depends on your setting.
Flow Control: There are two modes to choose in flow control, including
Enable and Disable. If flow control is set Enable, both
parties can send PAUSE frame to the transmitting device(s)
if the receiving port is too busy to handle. When it is set
Disable, there will be no flow control in the port. It drops the
packet if too much to handle.
Maximum Frame: This module offers 1518~9600 (Bytes) length to make the
long packet.
Excessive Collision Mode: There are two modes to choose when excessive collision
happened in half-duplex condition as below:
Discard: The “Discard” mode determines whether the MAC drop
frames after an excessive collision has occurred. If yes, a
frame is dropped after excessive collision. This is IEEE
Standard 802.3 half-duplex flow control operation.
Restart: The “Restart” mode determines whether the MAC
retransmits frames after an excessive collision has occurred.
If set, a frame is not dropped after excessive collisions, but
the backoff sequence is restarted. This is a violation of IEEE
Standard 802.3, but is useful in non-dropping half-duplex
flow control operation.
Description: Description of device ports can not include “ # % & ‘ + \.

connected to a working-well device, the Link will show the
link “Up”; otherwise, it will show “Down”. This is
determined by the hardware on both devices of the
connection.
No default value.
Speed / Duplex Mode: Display the speed and duplex of all port. There are three
speeds 10Mbps, 100Mbps and 1000Mbps supported for TP
media, and the duplex supported is half duplex and full
duplex. If the media is 1Gbps fiber, it is 1000Mbps
supported only. The status of speed/duplex mode is
determined by 1) the negotiation of both local port and link
partner in “Auto Speed” mode or 2) user setting in “Force”
mode. The local port has to be preset its capability.
Default: None, depends on the result of the negotiation.
Flow Control: Show each port’s flow control status. There are two types of
flow control in Ethernet, Backpressure for half-duplex
operation and Pause flow control (IEEE802.3x) for
full-duplex operation. The switch supports both of them.

The VLAN Mode Selection function includes five modes: Port-based, Tag- based, Metro
Mode, Double-tag and Disable, you can choose one of them by pulling down list and
selecting an item. Then, click <Apply> button, the settings will take effect immediately.
Parameter description:
VLAN Mode: Port-based -
Port-based VLAN is defined by port. Any packet coming in
or outgoing from any one port of a port-based VLAN will be
accepted. No filtering criterion applies in port-based VLAN.
The only criterion is the physical port you connect to. For
example, for a port-based VLAN named PVLAN-1 contains
port members Port 1&2&3&4. If you are on the port 1, you
can communicate with port 2&3&4. If you are on the port 5,
then you cannot talk to them. Each port-based VLAN you
built up must be assigned a group name. This switch can
support up to maximal 8 port-based VLAN groups.
Tag-based -
Tag-based VLAN identifies its member by VID. This is
quite different from port-based VLAN. If there are any more
rules in ingress filtering list or egress filtering list, the packet
will be screened with more filtering criteria to determine if it
can be forwarded. The switch supports supplement of 802.1q.
Page 52
VigorSwitch G2240 User’s Guide

characters. The maximal length is 15 characters.
VID: VLAN identifier. Each tag-based VLAN group has a unique
VID. It appears only in tag-based and Double-tag mode.
IGMP: IGMP proxy enables the switch to issue IGMP host
messages on behalf of hosts that the system discovered
through standard IGMP interfaces. The system acts as a
proxy for its hosts. This switch can be set IGMP function
“Enable” or “Disable” by VLAN group. If the VLAN
group IGMP proxy is disabled, the switch will stop the
exchange of IGMP messages in the VLAN group members.
If the VLAN group IGMP proxy is enabled, the switch will
support the exchange of IGMP messages in the VLAN group
members and follow up IGMP proxy router port
configuration, which connects to a router closer to the root
of the tree. This interface is the upstream interface. The
router on the upstream interface should be running IGMP.
Page 53
VigorSwitch G2240 User’s Guide
47
You enable IGMP on the interfaces that connect the system
to its hosts that are farther away from the root of the tree.
These interfaces are known as downstream interfaces.
PVLAN: Private VLAN ID identifier. Each Private VLAN group has
a unique VID. Private VLAN contains switch ports that
cannot communicate with each other but can access another
network. It appears only in tag-based and Double-tag mode.
GVRP-P: GVRP Propagation identifier. GVRP allows the propagation
of VLAN information from device to device. With GVRP, a
single switch is manually configured with all the desired
VLANs for the network, and all other switches on the
network learn those VLANs dynamically.
Port Members: This is used to enable or disable if a port is a member of the
new added VLAN, “Enable” means it is a member of the
VLAN. Just tick the check box (;) beside the port x to
enable it.
Add new VLAN: Please click on <Add new VLAN> to create a new
Tag-based VLAN. Input the VLAN name as well as VID,
configure the SYM-VLAN function and choose the member
by ticking the check box beside the port No., then, press the

Function name:
VLAN Port Configuration
Function description:
In VLAN Tag Rule Setting, user can input VID number to each port. The range of VID
number is from 1 to 4094. User also can choose ingress filtering rules to each port. There
are two ingress filtering rules which can be applied to the switch. The Ingress Filtering
Rule 1 is “forward only packets with VID matching this port’s configured VID”. The
Ingress Filtering Rule 2 is “drop untagged frame”. You can also select the Role of each
port as Access, Trunk, or Hybrid.
Parameter description:
Port 1-24: Port number.
VLAN Aware: Based on IEEE 802.1Q VLAN tag to forward packet.
Ingress Filtering: Discard other VLAN group packets, only forward this port
joined VLAN group packets.
Frame Type: All: Forward all tagged and untagged packets.
Tagged: Forward tagged packets only and discard untagged
packets.
PVID: This PVID range will be 1-4094. Before you set a number x
as PVID, you have to create a Tag-based VLAN with VID x.
For example, if port x receives an untagged packet, the
switch will apply the PVID (assume as VID y) of port x to
tag this packet, the packet then will be forwarded as the
tagged packet with VID y.
Role: This is an egress rule of the port. Here you can choose
Access, Trunk or Hybrid. Trunk means the outgoing packets
must carry VLAN tag header. Access means the outgoing
Page 56
VigorSwitch G2240 User’s Guide
50
packets carry no VLAN tag header. If packets have double
VLAN tags, one will be dropped and the other will still be
left. As to Hybrid, it is similar to Trunk, and both of them
will tag-out. When the port is set to Hybrid, its packets will
be untagged out if the VID of the outgoing packets with tag
is the same as the one in the field of Untag VID of this port.
Untag VID: Valid range is 1~4094. It works only when Role is set to
Hybrid.
Double Tag: Double-tag mode belongs to the tag-based mode, however, it
would treat all frames as the untagged ones, which means
that tag with PVID will be added into all packets. Then,
these packets will be forwarded as Tag-based VLAN. So, the
incoming packets with tag will become the double-tag ones.
Scroll to enable the function and default is Disable.

GVRP is an application based on Generic Attribute Registration Protocol (GARP), mainly
used to automatically and dynamically maintain the group membership information of the
VLANs. The GVRP offers the function providing the VLAN registration service through a
GARP application. It makes use of GARP Information Declaration (GID) to maintain the
ports associated with their attribute database and GARP Information Propagation (GIP) to
communicate among switches and end stations. With GID information and GIP, GVRP
state machine maintain the contents of Dynamic VLAN Registration Entries for each
VLAN and propagate these information to other GVRP-aware devices to setup and update
their knowledge database, the set of VLANs associated with currently active members, and
through which ports these members can be reached.

The switch support four QoS queues per port with strict or weighted fair queuing
scheduling. There are 24 QoS Control Lists (QCL) for advance programmable QoS
classification, based on IEEE 802.1p, Ethertype, VID, IPv4/IPv6 DSCP and UDP/TCP
ports and ranges.
High flexibility in the classification of incoming frames to a QoS class. The QoS
classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4
TCP/UDP port numbers, and user priority of tagged frames. This QoS classification
mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame
is used throughout the device for providing queuing, scheduling, and congestion control
guarantees to the frame according to what was configured for that specific QoS class.
The switch supports advanced memory control mechanisms providing excellent
performance of all QoS classes under any traffic scenario, including jumbo frame, a super
priority queue with dedicated memory and strict highest priority in the arbitration. The
ingress super priority queue allows traffic recognized as CPU traffic to be received and
queued for transmission to the CPU even when all the QoS class queues are congested.

Any Network Management System (NMS) running the Simple Network Management
Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided
that the Management Information Base (MIB) is installed correctly on the managed devices.
The SNMP is a protocol that is used to govern the transfer of information between SNMP
manager and agent and traverses the Object Identity (OID) of the management Information
Base (MIB), described in the form of SMI syntax. SNMP agent is running on the switch to
response the request issued by SNMP manager.
Basically, it is passive except issuing the trap information. The switch supports a switch to
turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be
started up. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP
manager. If the field SNMP is set “Disable”, SNMP agent will be de-activated, the related
Community Name, Trap Host IP Address, Trap and all MIB counters will be ignored.
Function name:
SNMP Configuration
Function description:
This function is used to configure SNMP settings, community name, trap host and public
traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by
identifying both community names, then it can access the MIB information of the target
device. So, both parties must have the same community name. Once completing the setting,
click <Apply> button, the setting takes effect.

Parameters description:
SNMP: The term SNMP here is used for the activation or
de-activation of SNMP. Default is Enable.
Get/Set/Trap Community: Community name is used as password for authenticating if
the requesting network management unit belongs to the
same community group. If they both don’t have the same
community name, they don’t belong to the same group.
Hence, the requesting network management unit can not
access the device with different community name via SNMP
protocol; If they both have the same community name, they
can talk each other.
Community name is user-definable with a maximum length
of 15 characters and is case sensitive. There is not allowed to
put any blank in the community name string. Any printable
character is allowable.
The community name for each function works independently.
Each function has its own community name. Say, the
community name for GET only works for GET function and
can’t be applied to other function such as SET and Trap.
Default SNMP function: Enable
Default community name for GET: public
Default community name for SET: private

user-definable. To set up a trap host means to create a trap
manager by assigning an IP address to host the trap message.
In other words, the trap host is a network management unit
with SNMP manager receiving the trap message from the
managed switch with SNMP agent issuing the trap message.
6 trap hosts can prevent the important trap message from
losing.
For each public trap, the switch supports the trap event Cold
Start, Warm Start, Link Down, Link Up and Authentication
Failure Trap. They can be enabled or disabled individually.
When enabled, the corresponded trap will actively send a
trap message to the trap host when a trap happens. If all
public traps are disabled, no public trap message will be sent.
As to the Enterprise (no. 6) trap is classified as private trap,
which are listed in the Trap Alarm Configuration function
folder.
Default for all public traps: Enable.

The 24 Gigabit L2 Managed Switch access control list (ACL) is probably the most
commonly used object in the IOS. It is used for packet filtering but also for selecting types
of traffic to be analyzed, forwarded, or influenced in some way.
The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters
etc. Here we will just go over the standard and extended access lists for TCP/IP. As you
create ACEs for ingress classification, you can assign a policy for each port, the policy
number is 1-8, however, each policy can be applied to any port. This makes it very easy to
determine what type of ACL policy you will be working with.

ACL Ports Configuration
Function description:
The switch ACL function support up to 128 Access Control Entries (ACEs), using the
shared 128 ACEs for ingress classification. You can create an ACE and assign this ACE
for each port with <Any> or assign this ACE for a policy or assign this ACE for a port.
There are 8 policies, each port can select one of policy, then decides which of the
following actions would take according to the packet’s IPv4, EtherType, ARP Protocol,
MAC Parameters and VLAN parameters:
Packet Deny or Permit
Rate Limiter (Unit: pps)
Port Copy (1 – 24)
