1. Introduction
This managed switch is a Layer2 management switch with lots of advanced
network functions including VLAN, trunking, spanning tree, mirror port, IP
multicast, rate limit and port configuration. It supports console, telnet, http and
SNMP interface for switch management. IEEE 802.1x is supported for port
security application. These functions can meet most of the management request
for current network.

 This user's manual
2. Where To Place the Managed Switch
This switch can be placed on a flat surface (your desk, shelf or table).
Place the Intelligent Switch at a location with these connection considerations in
mind:
 The switch configuration does not break the rules as specified in Section 3.
 The switch is accessible and cables can be connected easily to it.
 The cables connected to the switch are away from sources of electrical
interference such as radio, computer monitor, and light fixtures.
 There is sufficient space surrounding the switch to allow for proper ventilation.
You can also install the 24+2G models Intelligent switch on a 19" rack with the
rack-mount kits.

3. Configure Network Connection
3.1 Connecting Devices to the Intelligent Switch
[ Connection Guidelines: ]
 For 10BaseT connection: Category 3 or 5 twisted-pair Ethernet cable
 For 100BaseTX connection: Category 5 twisted-pair Ethernet cable
 For 1000BaseTX connection: Category 5e or 6 twisted-pair Ethernet cable
 For UTP cable connection, always limit the cable distance to 100 meters (328
ft) as defined by IEEE specification
 If your switch has 100BaseFX/1000BaseSX/1000BaseLX ports, you can
connect long distance fiber optic cable to the switch.
 Because this switch supports Auto MDI/MDI-X detection on each UTP port,
you can use normal straight through cable for both workstation connection
and hub/switch cascading.
3.2 Connecting to Another Ethernet Switch/Hub
This Intelligent Switch can be connected to existing 10Mbps / 100Mbps /
1000Mbps hubs/switches. Because all UTP ports on the Intelligent Switch
support Auto MDI/MDI-X function, you can connect from any UTP port of the
Intelligent Switch to the MDI or MDI-X port of another hub/switch with Straight
Through or Crossover cables. If the switches have fiber-optic ports, you can
cascade them with fiber optic cable.

3
3.3 Application
A switch can be used to overcome the hub-to-hub connectivity limitations as well
as improve overall network performance. Switches make intelligent decisions
about where to send network traffic based on the destination address of the
packet. As a result, the switch can significantly reduce unnecessary traffic.
The example below demonstrates the switch ability to segment the network. The
number of nodes on each segment is reduced thereby minimizing network
contention (collisions) and boosting the available bandwidth per port.
With management function of the switch, network administrator is easy to
monitor network status and configure for different applications.

6. Manage / Configure the switch
6.1 Introduction of the management functions
This switch is a L2 management switch. It supports in-band management
function from SNMP, Http and Telnet interface. It also supports out-band
management function from RS232 console interface. Besides, it supports
network configuration functions, like VLAN, Trunking, Port Mirror, QoS, spanning
tree and software backup/update. Users can configure these functions for
different network applications. The following is a brief introduction about these
functions before the detail operation sections.
1. VLAN (Virtual LAN)
VLAN can divide the switch to several broadcast domains to prevent network
traffic between different user groups. This switch supports 802.1Q tag-based
VLAN and port-based VLAN. Users in the same VLAN can transfer data to
each other. The network traffic will be blocked if they are in different VLAN.
2. Trunk
If two switches are cascaded together, the bottleneck will happen at the
cascading connection. If more cables could be used for the cascading
connection, it will reduce the bottleneck problem. In normal case, switches
will become unstable because of traffic looping when more than one cable is
connected between them. If the switches support trunk function, they can treat
these cables as one connection between them. The traffic looping will not
happen between these cables and the switches will work stable with bigger
bandwidth between them.
This switch supports trunk function and users can configure it with the following
steps.
a.Enable trunk function.
b.Assign ports to a trunk. For example, assign Port 1,2,3 for Trunk 1.
Notes: About redundant application
The trunk connection supports redundant function. If any trunk cable is broken,
the traffic going through that cable will be transferred to another trunk cable
automatically. For example, if user port Port 6 is assigned to Port 1 in a Trunk
and Port 1 connection breaks, Port 2 will take over the traffic for Port 6
automatically. (It could be used for redundant application.)
3. Spanning Tree Protocol
Spanning tree is a protocol to prevent network loop in network topology. If
network loop happens, it will cause switches in the network unstable because
more and more traffic will loop in the network. If network loop happens,
spanning tree protocol will block one connection in the loop automatically. But
it will also cause a 30 seconds delay if any network connection is changed
because of the network topology detection operation of the protocol.
Because there could be more than one switch in the network, users can
configure this function for their network spanning tree application.

8
4. Port Mirror
This switch operates in store-and-forward algorithm so it is not possible to
monitor network traffic from another connection port. But the port mirror
function could copy packets from some monitored port to another port for
network monitor. This switch also provides DA/SA filtering function for
monitoring the traffic to/from some user.
5. QoS
For Quality of Service request in a network, packets could be classified to
different forwarding priorities. For real-time network traffic (like video, audio), it
needs higher priority than normal network traffic. With the definition of packet
priority, it could have 8 priority levels (from 0 to 7). This switch supports four
priority level queues on each port. It could be configured for port-based or
802.1P tagged based. User can define the mapping (0 – 7) to the four priority
queues.
6. Static Mac ID in ARL table
The switch can learn the Mac address from user’s packets and keep these Mac
address in the ARL table for store-and-forward table lookup operation. But
these Mac addresses will be deleted from ARL table after some time when
users do not send any packets to the switch. This operation is called aging
and the time is called aging time. It is 5 minutes normally (it could be changed
by users.) If users want to keep a Mac address always in ARL table for some
port, they can assign the Mac address to ARL table. These Mac ID are called
Static Mac address. This switch supports static Mac address assignment.
The static Mac address assignment will also limit the Mac address could be
used or rejected on the assigned port only with the port security configuration
function. For example, assigning “00-00-01-11-22-33” to Port 5 will always
keep this Mac ID alive on Port 5 but also limit this Mac address could work on
Port 5 only or rejected from Port 5 - depending on the setting of its port security
mode.
Note: About Static Mac Address Filter-in (port binding) function
There is a “Mac Security Configuration” function for port security mode. If it is
set to Accept mode, only these static Mac addresses can access network
through the assigned port. The other Mac addresses will be forbidden for
network access through that port. This function can be used for port binding
security application. Please refer to Section 6.2 / 6.3 for the details of the Mac
address filter-in operation of the switch.
7. IEEE 802.1x Port Security Function
If the 802.1x function is enabled, the switch will act as an authenticator for
users accessing network through the switch. It will need a RADIUS server for
the authentication function. Users will be asked for username and password
before network access. If the RADIUS server authenticates it, the switch will
enable the port for network access. This function is very useful for network
security application to prevent illegal users access network through the switch.
This switch supports MD5, TLS and PEAP authentication types.

9
8. Rate Control
This function can limit the burst traffic rate for physical ports. The traffic could
be ingress traffic or egress traffic. This function can protect the network
bandwidth usage by different users.
9. IP Multicast with IGMP Snooping
IP multicast function can forward packets to a group of users connected on
different ports. The user group is learned by the switch from the packets from
IGMP active router with IGMP snooping function. It is often used for video
applications.
10. Protected Port
This function can protect a port from communicating with some other ports.
Even these ports are in the same VLAN. This protection is still valid. For
example, Port 1,2,3,4 are marked as protected ports. Port 1,2,3,4 cannot
communicate with each other, but they can communicate with the other ports.
This is for port isolation application though they are in the same VLAN.
11. Software Backup/Update
This switch supports backup and update functions for its internal software and
its network configuration. It could be done in three ways.
a.From console when booting: doing by Xmodem protocol and by terminal
program for boot code and run-time code updating.
b.From console/Telnet when running: doing by TFTP protocol and it will need a
TFTP server in network for run-time code and configuration backup/update.
c. From web browser: doing by http protocol and by web browser for run-time
code and configuration backup/update.

10
6.2 Management with Console Connection
Please follow the steps to complete the console hardware connection first.
1. Connect from the console port of the switch to COM port of PC with the
console cable.
2. Start the terminal program. Create a new connection and select COM port of
PC used for the console. Set the configuration of the terminal as
[38400,8,N,1]. (With Windows, you can find the terminal program in [Start] ->
[Programs] -> [Accessory Programs] -> [Communication] -> [Terminal]. If you
cannot find it, please install it from your Windows Installation Disk. Please
refer to your Windows user manual for the installation.)
3. Power on the switch.
If everything is correct, the booting screen will appear in the terminal program
when the switch is powered on. It will stop at the following screen after some
initializing messages.

These two commands will show the sub-command list for set command.
2.2 set 1qvlan command
This command is used to configure 802.1Q VLAN of the switch.
Its syntax is . . .
>set 1qvlan
[Argument List]
enable......... Set 802.1Q VLAN enabled.
disable........ Set 802.1Q VLAN disabled.
ingressfilter.. Set ingress filter Enable or Disable.
create......... Create new 802.1Q vlan with specified VLAN ID and VLAN Name.
modify......... Modify the setting of a 802.1Q VLAN.
pvid........... Set the Port VLANID of specified port.
mgrpvid........ Set the Port VLANID of management port.
priority....... Set the priority for tag of specified port.
mode........... Set the VLAN Mode.
enable and disable sub-commands are used to enable/disable 802.1Q
VLAN function of the switch.
ingressfilter sub-command is used to enable/disable VLAN filtering executed
at ingress port.
Enable: the VLAN filtering function will be executed when packet is received
at ingress port. If the ingress port is in the same VLAN of the received packet,
this packet will go to forwarding stage. Otherwise, the packet will be
discarded by VLAN filtering at ingress port.
Disable: the VLAN filtering function will be executed when packet is
forwarded to egress port.
create sub-command is used to create a static 802.1Q VLAN. For example,
“set 1qvlan create 20 ABC” will create a static 802.1Q VLAN with ID 20 and
name “ABC”.
modify sub-command is used to modify a static 802.1Q VLAN setting.
Its syntax is . . .
>set 1qvlan modify
Syntax : set 1qvlan modify [+|-] [port#] VLANID [1:<tagged>|0:<untagged>]
Examples : Set 1qvlan +1+5-7 2 1
Description: Add port 1,5 to VLAN 2 as tagged port and remove port 7 from VLAN 2
pvid sub-command is used to set Port VLAN ID. The Port VLAN ID is used
as the VLAN ID for tag adding when untagged packet is translated to tagged
packet. For example, “set 1qvlan pvid 3 10” will set the PVID of Port 3 as 10.
mgrpvid sub-command is used to select the VLAN group that is allowed to
management the switch. Only the users in the selected VLAN can manage

13
the switch by Http, Telnet and SNMP. For example, “set 1qvlan mgrpvid 5”
will allow the users in the VLAN with VLAN ID 5 to manage the switch
remotely.
priority sub-command is used to set port priority for tag adding when
untagged packet is translated to tagged packet. For example, “set 1qvlan
priority 3 2” will set the port priority of Port 3 as 2. The priority information in
tag will be filled with 2 when the untagged packet coming to Port 3 is
translated to tagged packet.
mode sub-command is used to select the VLAN mode for 802.1Q VLAN
operation. There are three modes for VLAN function –SVL (Shared VLAN),
IVL (Individual VLAN) and SVL/IVL.
Syntax : set 1qvlan mode [0:SVL|1:IVL]
Examples : Set 1qvlan mode 0
Description: Set current vlan mode as SVL
0: SVL mode
1: IVL mode
2: SVL/IVL mode
SVL mode – the switch will do packet forwarding according to its Mac
address directly. It is the normal VLAN operation of switch.
IVL mode – the switch will do packet forwarding according to its Mac address
and VLAN ID both. It is for some special VLAN applications.
SVL/IVL mode – its operation is the same as IVL mode but for untagged port
is used as the uplink port in MDU/MTU application.
For most VLAN applications, SVL mode is suggested.
2.3 set admin command
This command is used to modify the user name and password for
administrator.
2.4 set age command
This command is used to change the aging time of the switch.
Its syntax is . . .
>set age
Syntax: set age [time]
[time]: 0: disable aging operation
1~65535: aging time in seconds, default is 300.
The aging time is 300 seconds default and its valid range is 0 ~ 65535. If
[time] is set to 0, the aging function will be disabled.
(Notes: Disable aging is different from static Mac ID in ARL table. The
connection port is fix for a static Mac ID, but the connection port could be
changed for a Mac ID with no aging.)
2.5 set arl command
This command is for adding static Mac ID to ARL table of the switch.
Its syntax is . . .
>set arl
Set ARL [xx-xx-xx-xx-xx-xx] [port#]

14
For example, “set ARL 00-00-01-11-22-33 5” will add a static Mac ID “00-00-
01-11-22-33” to ARL table for Port 5 and this Mac ID will never be aged out
from Port 5.
Note: Because the static Mac address is fixed on the assigned port by the
switch, the static Mac address can access network through the assigned port
only. It will fail to access network through other ports of the switch.
2.6 set automode command
This command is used to set the auto mode function of connection port when
it is forced to some special setting instead of fully auto-negotiation. There are
two modes for it – an(auto negotiation) and ad(auto detection).
an mode – if the auto. function of a port is disabled in port configuration, the
switch will disable its auto-negotiation function and the Auto-MDIX function of
the port is also disabled. That is the real force-mode setting of the port.
ad mode – if the auto. function of a port is disabled in port configuration, the
switch will not disable its auto-negotiation function but just modify its auto-
negotiation attribute for the speed/duplex mode setting. And the Auto-MDIX
function of the port is still enabled.
Its syntax is …
>set automode
Valid mode [an:Auto Negotiation|ad:Auto Detect]
[Application]
If the connected device is auto-negotiation enabled and you want to force the
speed of the connection (for example, 10M/Half), you can select ad mode.
If the connected device is in forced mode (for example, 10M/Half) and it is
auto-negotiation disabled, you can use an mode and set the port to the same
configuration as the device in port configuration function.
You can select an mode or ad mode depending on your applications. In most
of connection cases, ad mode is suggested. But for 100FX connection, you
should select an mode and disable Auto. Set the port to 100/Full.
2.7 set dot1x command
This command is used to configure 802.1x function of the switch.
Its syntax is . . .
>set dot1x
[Argument List]
enable......... Set 802.1x enable
disable........ Set 802.1x disable
authmode....... Set 802.1x Auth Mode of a specified port
authport....... Set Authenticate Port of Radius Server
quiettime...... Set 802.1x Quiet Timeout Period
re_au.......... Set 802.1x Re-authentication
reauthcnt...... Set 802.1x Re-authentication Max Count

15
reauthtime..... Set 802.1x Re-authentication Timeout Period
reqcnt......... Set 802.1x Max Request Count
rsip........... Set Radius Server Address
shkey.......... Set 802.1x Shared Key
supptime....... Set 802.1x Supplicant Timeout Period
svrtime........ Set 802.1x Server Timeout Period
transparent.... Set 802.1x as transparent mode
txtime......... Set 802.1x Tx Timeout Period
enable sub-commands is used to enable 802.1x authentication function.
disable sub-command is used to disable 802.1x function.
authmode sub-command is used to set the authentication mode for a
physical port. Its syntax is . . .
set dot1x authmode [port#] [auto|fa|fu|no]
- auto: the authentication mode of the port depending on the authentication
result of the port
- fa (force-authenticated): will force the port always being authentication
successful in 802.1x process and the real authentication result will be
ignored.
- fu (force-unauthenticated): will force the port always being authentication
unsuccessful in 802.1x process and the real authentication result will be
ignored.
- none: 802.1x function will not be executed on the port, i.e. disabled on the
port.
authport sub-command is used to set the handshaking port number between
the switch and RADIUS server. It could be different for different RADIUS
servers.
quiettime sub-command is used to set the quiet time value between the
switch and the user before next authentication process when authentication
fail.
re_au sub-command is used to enable the re-authentication function of the
switch. When the re-authentication time is up, the switch will start the re-
authentication process.
reauthcnt sub-command is used to set max count for re-authentication
request in the re-authentication process. If the max count is met, it will
become un-authentication state. The valid value is 1~10.
reauthtime sub-command is used to set the timeout period of the re-
authentication process.
reqcnt sub-command is used to set max request timeout count between the
switch and RADIUS server before authentication fail. The valid value is 1~10.
rsip sub-command is used to set the IP address of RADIUS server.
shkey sub-command is used to set the security key between the switch and
RADIUS server.
supptime sub-command is used to set the timeout value between the switch
and users (called “supplicant” in 802.1x) after first identification. The valid
value is 0~65535.
svrtime sub-command is used to set the request timeout value between the
switch and RADIUS server. The valid value is 0~65535.

16
transparent sub-command is used to set the operation of 802.1x function to
transparent mode. In this mode, the switch will forward the 802.1x packets
only.
txtime sub-command is used to set the timeout value for the identification
request from the switch to users. The request will be re-tried until the
reauthcnt is met. After that, authentication fail message will be sent. The
valid value is 0~65535.
Note: This switch supports MD5, TLS and PEAP authentication types.
2.8 set guest command
This command is used to modify the user name and password for guest.
(The “guest” account is allowed to see the configuration/setting of the switch.
But the “guest” is not allowed to make any modification.)
2.9 set gvrp command
This command is used to enable/disable the GVRP function for 802.1Q
