User Manual
• TP Port and Cable Installation
⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used.
It means you do not have to tell from them, just plug it.
⇒ Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the
other end is connected to a network-aware device such as a workstation or a
server.
⇒ Repeat the above steps, as needed, for each RJ-45 port to be connected to a
Gigabit 10/100/1000 TP device.
Now, you can start having the switch in operation.
• Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power
supply will automatically convert the local AC power source to DC power. It does not
matter whether any connection plugged into the switch or not when power on, even
modules as well. After the power is on, all LED indicators will light up immediately
and then all off except the power LED still keeps on. This represents a reset of the
system.
• Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will
take about 30 seconds, after that, the switch will flash all the LED once and
automatically performs self-test and is in ready state.
2-1-2. Cabling Requirements
To help ensure a successful installation and keep the network performance
good, please take a care on the cabling requirement. Cables with worse
specification will render the LAN to work poorly.

2-1-2-1. Cabling Requirements for TP Ports
⇒ For Fast Ethernet TP network connection
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters.
⇒ Gigabit Ethernet TP network connection
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters. Cat. 5e is recommended.
2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module
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-SC.

2-1-2-3. Switch Cascading in Topology
• 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
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)
Table 2-2
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.

Case1: All switch ports are in the same local area network. Every port can access
each other (See Fig. 2-2).
Fig. 2-2 No VLAN Configuration Diagram
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.
Case2a: Port-based VLAN (See Fig.2-3).
1. The same VLAN members could not be in different switches.
2. Every VLAN members could not access VLAN members each other.
3. The switch manager has to assign different names for each VLAN groups
at one switch.

2-1-3-1. Configuring the Management Agent of 24 Fast Ethernet + 2 Gigabit L2
Managed Switch 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.
C Line 100-240V 50/60 Hz RS-232 DB-9 Connector

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,
Windows98SE/2000/XP HyperTerminal utility.

• Set IP Address, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-6 Console Management for details about the ex-factory
setting. They are default setting of 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.

• Managing GSW-2690 through Ethernet Port
Before you communicate with the switch, you have to finish first the
configuration of the IP address or to know the IP address of the switch. Then,
follow the procedures listed below.
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.
ssign a reasonable IP address,
For example:
IP = 192.168.1.100
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
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 Fig. 2-8 about the switch’s default IP
address information.
2. Run CLI or web browser and follow the menu. Please refer to Chapter 3

2-1-4. IP Address Assignment
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 in the Fig. 2-10. 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.

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

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.

Table 2-4
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.

Publication date: June, 2005
Revision A1
User Manual
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.
Fig. 2-11
First, IP Address: as shown in the Fig. 2-11, 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 in the Fig. 2-11, 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.

Table 3-1
After the managed switch has been finished configuration in the CLI via the
switch’s serial interface, you can browse it. For instance, type http://192.168.1.1
the address row in a browser, it will show the following screen (see Fig.3-1) 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 (See Fig. 3-1) or input
“Ctrl+Z” in CLI’s login screen (See Fig. 4-1~4-2) 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.

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.

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 2-1-4 “IP Address Assignment” in this manual.

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 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)).
32 bits
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 2-1-4 “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.

The switch supports DNS client function to re-route the mnemonic name
address to DNS server to get its associated IP address for accessing
Internet. User can specify a DNS IP address for the switch. With this, the
switch can translate a mnemonic name address into an IP address.
There are two ways to specify the IP address of DNS. One is fixed mode,
which manually specifies its IP address, the other is dynamic mode,
which is assigned by DHCP server while DHCP is enabled. DNS can
help you easily remember the mnemonic address name with the
meaningful words in it. Default is no assignment of DNS address.

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

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 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 nonzero, 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 switch offers Management Security Configuration function. With this
function, the manager can easily control the mode that the user connects to
the switch. According to the mode, users can be classified into two types:
Those who are able to connect to the switch (Accept) and those who are
unable to connect to the switch (Deny). Some restrictions also can be placed
on the mode that the user connect to the switch, for example, we can decide
that which VLAN VID is able to be accepted or denied by the switch, the IP
range of the user could be accepted or denied by the switch, the port that the
user is allowed or not allowed to connect with the switch, or the way of
controlling and connecting to the switch via Http, Telnet or SNMP.

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 address 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 become the
Master, two rows of buttons for group device will 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 device.
The most top-left button is only for Master device(See Fig.3-9). 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. 196_GSW-2690), 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 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 .

3-3. SNMP Configuration
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.

Trap:
In the switch, there are four trap hosts supported. Each of them has its
own community name and IP address; is 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.

3-4. DHCP Boot
The DHCP Boot function is used to spread the request broadcast packet into
a bigger time frame to prevent the traffic congestion due to broadcast packets from
many network devices which may seek its NMS, boot server, DHCP server and
many connections predefined when the whole building or block lose the power and
then reboot and recover. At this moment, a bunch of switch or other network device
on the LAN will try its best to find the server to get the services or try to set up the
predefined links, they will issue many broadcast packets in the network.
The switch supports a random delay time for DHCP and boot delay for each
device. This suppresses the broadcast storm while all devices are at booting stage
in the same time. The maximum user-defined delay time is 30 sec. If DHCP
Broadcasting Suppression function is enabled, the delay time is set randomly,
ranging from 0 to 30 seconds, because the exactly delay time is computed by the
switch itself. The default is “Disable”.

3-5. IGMP Snooping
The function, IGMP Snooping, is used to establish the multicast groups to
forward the multicast packet to the member ports, and, in nature, avoids wasting the
bandwidth while IP multicast packets are running over the network. This is because
a switch that does not support IGMP or IGMP Snooping can not tell the multicast
packet from the broadcast packet, so it can only treat them all as the broadcast
packet. Without IGMP Snooping, the multicast packet forwarding function is plain
and nothing is different from broadcast packet.
A switch supported IGMP Snooping with the functions of query, report and
leave, a type of packet exchanged between IP Multicast Router/Switch and IP
Multicast Host, can update the information of the Multicast table when a member
(port) joins or leaves an IP Multicast Destination Address. With this function, once a
switch receives an IP multicast packet, it will forward the packet to the members
who joined in a specified IP multicast group before.

gather the Membership report message to update the database
of the Multicast table. By the way, this also reduces the
unnecessary multicast traffic.
In Passive Snooping mode, the IGMP snooping will not
periodically poll the hosts in the groups. The switch will send a
Membership Query message to all hosts only when it has
received a Membership Query message from a router.

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..
Each tag-based VLAN you built up must be assigned VLAN name
and VLAN ID. Valid VLAN ID is 1-4094. User can create total up to
256 Tag VLAN groups.
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 26 port-based VLAN groups.

Symmetric Vlan:
This is a Ingress Rule (Rule 1, The Ingress Filtering Rule 1 is “forward
only packets with VID matching this port’s configured VID”.). For example,
if port 1 receives a tagged packet with VID=100 (VLAN name=VLAN100),
and if Symmetric-Vlan function is enabled, the switch will check if port 1
is a member of VLAN100. If yes, the received packet is forwarded;
otherwise, the received packet is dropped.
Note: If Symmetric is enabled and port 1, for example, receives an untagged packet,
the switch will apply the PVID of port 1 to tag this packet, the packet then will
be forwarded. But if the PVID of port 1 is not 100, the packet will be dropped.
SVL:
While SVL is enable, all VLANs use the same filtering database storing
the membership information of the VLAN to learn or look up the
membership information of the VLAN. While SVL is disable, it means
learning mode is IVL. In this mode, different VLAN uses different filtering
database storing the membership information of the VLAN to learn or
look up the information of a VLAN member.
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 Tagbased VLAN. So, the incoming packets with tag will become the doubletag ones.

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.
Default Priority:
If a tagged frame does not own a VID, the Ingress rule will plus a tag with
default priority and PVID.
Drop Untag:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged frame. If the former is the
case, then the packets with tagged or untagged will be processed. If the

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.

Protocol is “Disable”.
Parameter description:
Spanning Tree Protocol:
Set 802.1W Rapid STP function Enable / Disable. Default is “Disable”
Bridge Priority:
The lower the bridge priority is, the higher priority it has. Usually, the
bridge with the highest bridge priority is the root. If you want to have the
GSW-2690 as root bridge, you can set this value lower than that of
bridge in the LAN. The valid value is 0 ~ 61440. The default is 32768.
Hello Time:
Hello Time is used to determine the periodic time to send normal BPDU
from designated ports among bridges. It decides how long a bridge
should send this message to other bridge to tell I am alive. When the
GSW-2690 is the root bridge of the LAN, for example, all other bridges
will use the hello time assigned by this switch to communicate with each
other. The valid value is 1 ~ 10 in unit of second.
Default is 2 seconds.
Max. Age:
When the GSW-2690 is the root bridge, the whole LAN will apply this
figure set by this switch as their maximum age time. When a bridge
received a BPDU originated from the root bridge and if the message age
conveyed in the BPDU exceeds the Max. Age of the root bridge, the
bridge will treat the root bridge malfunctioned and issue a Topology
Change Notification (TCN) BPDU to all other bridges. All bridges in the
LAN will re-calculate and determine who the root bridge is. The valid
value of Max. Age is 6 ~ 40 seconds. Default is 20 seconds.

Forward Delay:
You can set the root bridge forward delay time. This figure is set by root
bridge only. The forward delay time is defined as the time spent from
Listening state moved to Learning state and also from Learning state
moved to Forwarding state of a port in bridge. The forward delay time
contains two states, Listening state to Learning state and Learning state
to Forwarding state. It assumes that forward delay time is 15 seconds,
then total forward delay time will be 30 seconds. This has much to do
with the STP convergent time which will be more than 30 seconds
because some other factors.
The valid value is 4 ~ 30 seconds, default is 15 seconds.
Force Version:
Two options are offered for the user’s choosing STP algorithm. One is
RSTP and the other is STP. If STP is chosen, RSTP will run as a legacy
STP. The switch supports RSTP (802.1w) which is backward compatible
with STP (802.1d).

each Port Status item. User also can set “Path Cost” and “Priority” of each port
by filling in the desired value and set “Admin Edge Port” and “Admin Point To
Point” by selecting the desired item.
Parameter description:
Port Status:
It displays the current state of a port. We cannot manually set it because
it displays the status only. There are three possible states. ( according to
802.1w specification)
DISCARDING state indicates that this port can neither forward packets
nor contribute learning knowledge.
Notice: Three other states (Disable state, BLOCKING state and LISTENING
state) defined in the 802.1d specification are now all represented as
DISCARDING state.
LEARNING state indicates this port can now contribute its learning
knowledge but cannot forward packets still.
FORWARDING state indicates this port can both contribute its learning
knowledge and forward packets normally.
Path Cost Status:
It is the contribution value of the path through this port to Root Bridge.
STP algorithm determines a best path to Root Bridge by calculating the
sum of path cost contributed by all ports on this path. A port with a
smaller path cost value would become the Root Port more possibly.
Configured Path Cost:
The range is 0 – 200,000,000. In the switch, if path cost is set to be zero,
the STP will get the recommended value resulted from auto-negotiation
of the link accordingly and display this value in the field of Path Cost
Status. Otherwise, it may show the value that the administrator set up in
Configured Path Cost and Path Cost Status.

802.1w RSTP recommended value: (Valid range: 1 – 200,000,000)
Priority:
Priority here means Port Priority. Port Priority and Port Number are
mixed to form the Port ID. Port IDs are often compared in order to
determine which port of a bridge would become the Root Port. The range
is 0 – 240.
Default is 128.
Admin Edge Port:
If user selects “Yes”, this port will be an edge port. An Edge Port is a port
connected to a device that knows nothing about STP or RSTP. Usually,
the connected device is an end station. Edge Ports will immediately
transit to forwarding state and skip the listening and learning state
because the edge ports cannot create bridging loops in the network. This
will expedite the convergence. When the link on the edge port toggles,
the STP topology keeps unchanged. Unlike the designate port or root
port though, an edge port will transit to a normal spanning-tree port
immediately if it receives a BPDU.
10 Mbps : 2,000,000
100 Mbps : 200,000
1 Gbps : 20,000
Default: 0
Default: No
Admin Point To Point:
We say a port is a point-to-point link, from RSTP’s view, if it is in fullduplex mode but is shared link if it is in half-duplex mode. RSTP fast
convergence can only happen on point-to-point links and on edge ports.
This can expedite the convergence because this will have the port fast
transited to forwarding state.
There are three parameters, Auto, True and False, used to configure the
type of the point-to-point link. If configure this parameter to be Auto, it
means RSTP will use the duplex mode resulted from the auto-negotiation.
In today’s switched networks, most links are running in full-duplex mode.
For sure, the result may be half-duplex, in this case, the port will not fast
transit to Forwarding state. If it is set as True, the port is treated as pointto-point link by RSTP and unconditionally transited to Forwarding state. If
it is set as False, fast transition to Forwarding state will not happen on
this port.

M Check:
Migration Check. It forces the port sending out an RSTP BPDU instead
of a legacy STP BPDU at the next transmission. The only benefit of this
operation is to make the port quickly get back to act as an RSTP port.
Click <M Check> button to send a RSTP BPDU from the port you
specified.

3-10. Trunking Configuration
The Port Trunking Configuration is used to configure the settings of Link
Aggregation. You can bundle more than one port with the same speed, full duplex
and the same MAC to be a single logical port, thus the logical port aggregates the
bandwidth of these ports. This means you can apply your current Ethernet
equipments to build the bandwidth aggregation. For example, if there are three
Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth
three times as high as a single Fast Ethernet port has.
The switch supports two kinds of port trunking methods:
LACP:
Ports using Link Aggregation Control Protocol (according to IEEE
802.3ad specification) as their trunking method can choose their unique
LACP GroupID (1~3) to form a logic “trunked port”. The benefit of using
LACP is that a port makes an agreement with its peer port before it
becomes a ready member of a “trunk group” (also called aggregator).
LACP is safer than the other trunking method - static trunk.
The switch LACP does not support the followings:
Link Aggregation across switches
Aggregation with non-IEEE 802.3 MAC link
Operating in half-duplex mode
Aggregate the ports with different data rates
Static Trunk:
Ports using Static Trunk as their trunk method can choose their unique
Static GroupID (also 1~3, this Static groupID can be the same with
another LACP groupID) to form a logic “trunked port”. The benefit of
using Static Trunk method is that a port can immediately become a
member of a trunk group without any handshaking with its peer port. This
is also a disadvantage because the peer ports of your static trunk group
may not know that they should be aggregate together to form a “logic
trunked port”. Using Static Trunk on both end of a link is strongly
recommended. Please also note that low speed links will stay in “not
ready” state when using static trunk to aggregate with high speed links.
As to system restrictions about the port aggregation function on the switch,
In the management point of view, the switch supports maximum 3 trunk groups for
LACP and additional 3 trunk groups for Static Trunk. But in the system capability
view, only 3 “real trunked” groups are supported. An LACP trunk group with more
than one ready member-ports is a “real trunked” group. An LACP trunk group with
only one or less than one ready member-ports is not a “real trunked” group. Any
Static trunk group is a “real trunked” group.

Per Trunking Group supports a maximum of 4 ready member-ports. Please
note that some decisions will automatically be made by the system while you are
configuring your trunking ports. Trunk Setting Rules are listed below:
Rule1: Maximum 3 groups are allowed
Rule 2: The members of each group cannot exceed more than 4 ports
Rule 3: Group 1 and 2 cannot exist member 25 and 26 port
Rule 4: Group 3 cannot exist member from 1 to 24 port

Function name:
Port Setting/Status
Function description:
Port setting/status is used to configure the trunk property of each and every
port in the switch system.
Parameter description:
Method:
This determines the method a port uses to aggregate with other ports.
None:
A port does not want to aggregate with any other port should
choose this default setting.
LACP:
A port use LACP as its trunk method to get aggregated with other
ports also using LACP.
Static:
A port use Static Trunk as its trunk method to get aggregated with
other ports also using Static Trunk.
Group:
Ports choosing the same trunking method other than “None” must be
assigned a unique Group number (i.e. Group ID, valid value is from 1 to
8) in order to declare that they wish to aggregate with each other.
Active LACP:
This field is only referenced when a port’s trunking method is LACP.
Active:
An Active LACP port begins to send LACPDU to its link partner right
after the LACP protocol entity started to take control of this port.
Passive:
A Passive LACP port will not actively send LACPDU out before it
receives an LACPDU from its link partner.

Aggtr:
Aggtr is an abbreviation of “aggregator”. Every port is also an aggregator,
and its own aggregator ID is the same as its own Port No. We can regard
an aggregator as a representative of a trunking group. Ports with same
Group ID and using same trunking method will have the opportunity to
aggregate to a particular aggregator port. This aggregator port is usually
the port with the smallest Port No. within the trunking group.
Status:
This field represents the trunking status of a port which uses a trunking
method other than “None”. It also represents the management link status
of a port which uses the “None” trunking method. “---“ means “not ready”
