1. Introduction
1-1. Overview of MSM-6226
MSM-6226, a 24 Fast Ethernet + 2 Gigabit L2 Managed Switch, which
implemented 24 10/100Mbps TP + 2 Gigabit dual media ports with TP/SFP(or
GBIC), is a standard switch that meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet
and Ethernet specifications. The switch can be managed through RS-232 serial port
via directly connection, or through Ethernet port using Telnet or Web-based
management unit, associated with SNMP agent. With the SNMP agent, the network
administrator can logon the switch to monitor, configure and control each port’s
activity in a friendly way. The overall network management is enhanced and the
network efficiency is also improved to accommodate high bandwidth applications.
In addition, the switch features comprehensive and useful function such as DHCP
Option 82, QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking,
Bandwidth Control, Port Security, SNMP/RMON and IGMP Snooping capability via
the intelligent software. It is suitable for both metro-LAN and office application.
Others the new FW increase support the Power saving for reduce the power
consumption with "ActiPHY Power Management" and "PerfectReach Power
Management" two technique. The device also support DHCP Relay function The
DHCP Relay Agent makes it possible for DHCP broadcast messages to be sent
over routers that do not support forwarding of these types of messages. The DHCP
Relay Agent is therefore the routing protocol that enables DHCP clients to obtain IP
addresses from a DHCP server on a remote subnet, or which is not located on the
local subnet.
The switch also supports the IEEE Standard─ ─802.1AB （ Link Layer
Discovery Protocol），Provide more easy debug tool and enhance the networking
management availability, Others it can provide auto-discovery device and topology
providing.

Key Features in the Device
1
Publication date:March., 2011
Revision A1
Page 14
DHCP Snooping:
This feature enables the DHCP Snooping (MSM-6226 switch) to include
information about client when forwarding DHCP requests from a DHCP
client to a DHCP server via Trust Port. DHCP snooping can be configured
on LAN switches to harden the security on the LAN to only allow clients with
specific IP/MAC addresses to have access to the network. In short, DHCP
snooping ensures IP integrity on a Layer 2 switched domain.
QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Link Layer Discovery Protocol (LLDP):
IEEE Standard──802.1AB （Link Layer Discovery Protocol），Provide
more easy debug tool and enhance the networking management availability,
Others it can provide auto-discovery device and topology providing
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 4K active
VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:
Support ingress and egress per port bandwidth control.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON:
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) and
so on.
IGMP Snooping:
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.
Page 15
• When queried, sends group membership reports to the
group.
• 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.
• 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).
Power Saving:
The Power saving using the "ActiPHY Power Management" and
"PerfectReach Power Management" two techniques to detect the client idle
and cable length automatically and provides the different power. It could
efficient to save the switch power and reduce the power consumption.
Access Control List (ACL):
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.
IP-MAC-Port Binding:
The IP network layer uses a four-byte address. The Ethernet link layer uses
a six-byte MAC address. Binding these two address types together allows
the transmission of data between the layers. The primary purpose of IPMAC binding is to restrict the access to a switch to a number of authorized
users. Only the authorized client can access the Switch’s port by checking
the pair of IP-MAC Addresses and port number with the pre-configured
database. If an unauthorized user tries to access an IP-MAC binding
enabled port, the system will block the access by dropping its packet.
Q-in-Q VLAN for performance & security:
The VLAN feature in the switch offers the benefits of both security and
performance. VLAN is used to isolate traffic between different users and
thus provides better security. Limiting the broadcast traffic to within the
same VLAN broadcast domain also enhances performance. Q-in-Q, the use
of double VLAN tags is an efficient method for enabling Subscriber
Aggregation. This is very useful in the MAN.
MVR:
Multicast VLAN Registration (MVR) can support carrier to serve content
provider using multicast for Video streaming application in the network.
Each content provider Video streaming has a dedicated multicast VLAN.
The MVR routes packets received in a multicast source VLAN to one or
more receive VLANs. Clients are in the receive VLANs and the multicast
server is in the source VLAN.

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.

Place the Chassis into the 19-inch wiring closet rail and locate it at the proper
position. Then, fix the Chassis by screwing it.
2-1-3. 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.
2-1-3-1. 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.
2-1-3-2. 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 LC.

2-1-3-3. 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
11.12/m Cat. 5 TP Wire:
Fiber Cable : 10.10/m TP to fiber Converter: 56
Bit Time unit : 1ns (1sec./1000 Mega bit)
Fiber Cable: 1.0/m
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

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. 2-3).
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.2-4).
Fig. 2-4 Port-based VLAN Diagram
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.

Case 2b: Port-based VLAN (See Fig.2-5).
1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.
2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could
access VLAN4 members.
3.
VLAN3 members could not access VLAN1, VLAN2 and VLAN4.
4. VLAN4 members could not access VLAN1 and VLAN3 members, but they could
access VLAN2 members.
Case3a: The same VLAN members can be at different switches with the same VID
(See Fig. 2-6).

Note: Please first modify the IP address, Subnet mask, Default gateway and DNS
through RS-232 console, and then do the next.
2-1-4-1. Configuring the Management Agent of MSM-6226 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.

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.

Set IP Address, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-7 CLI Management for details about ICPDAS
Manufacture’s 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 MSM-6226 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.
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. 2-9 about the switch’s default IP
address information.
2. Run CLI or web browser and follow the menu. Please refer to Chapter 3
and Chapter 4.

Page 29
2-1-5. 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. 2-11. 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
Fig. 2-11 IP address structure
32 bits
With the classful addressing, it divides IP address into three classes, class A,
class B and class C. The rest of IP addresses are for multicast and broadcast. The
bit length of the network prefix is the same as that of the subnet mask and is
denoted as IP address/X, for example, 192.168.1.0/24. Each class has its address
range described below.
Class A:
Address is less than 126.255.255.255. There are a total of 126 networks can
be defined because the address 0.0.0.0 is reserved for default route and
127.0.0.0/8 is reserved for loopback function.
Bit # 0 1 7 8 31
0
Network address Host address
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.
Bit # 0 1 2 3 23 24 31

Network address Host address
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.

Page 32
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.
Fig. 2-12
First, IP Address: as shown in the Fig. 2-12, 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. 2-12, 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.

3. Operation of Web-based
Management
This chapter instructs you how to configure and manage the MSM-6226
through the web user interface it supports, to access and manage the 24
10/100Mbps TP + 2 Gigabit dual media ports with TP/SFP(or GBIC)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
Subnet Mask
Default Gateway
Username
Password
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 in
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.
192.168.1.1
255.255.255.0
192.168.1.254
admin
admin
Table 3-1
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.
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.

3-1-2. IP Configuration
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.
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.

Publication date:March., 2011
Revision A1
Page 43
Subnet mask is made for the purpose to get more network address
Network ID
Host ID
Network ID
Host ID
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 2-1-5 “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:
It is Domain Name Server used to serve the translation between IP
address and name address.
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.
Subnet number
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.
Default: 0.0.0.0

3-1-3. Time Configuration
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 an user-defined NTP
server IP address. The time zone is Greenwich-centered which uses the expression
form of GMT+/- xx hours.
Function name:
Time
Function description:
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.

Page 45
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.
Default: Year = 2000, Month = 1, Day = 1
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.
Hour = 0, Minute = 0, Second = 0
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 following parameters are configurable for the function Daylight

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.
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_ MSM-6226 ), 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. DHCP Relay
The Dynamic Host Configuration Protocol (DHCP) is a service that runs at the
application layer of the TCP/IP protocol stack to dynamically assign IP addresses to
DHCP clients. DHCP clients request IP addresses, and obtain leases for IP
addresses from the DHCP server.
The DHCP Relay Agent makes it possible for DHCP broadcast messages to
be sent over routers that do not support forwarding of these types of messages. The
DHCP Relay Agent is therefore the routing protocol that enables DHCP clients to
obtain IP addresses from a DHCP server on a remote subnet, or which is not
located on the local subnet. If you have no configured DHCP Relay Agent, your
clients would only be able to obtain IP addresses from the DHCP server which is on
the same subnet.
If you are using the switches to insert DHCP Option 82 information and you
are also using as DHCP relay-agents (via ‘ip helper-address’), you’ll notice right
away that your Option 82 enabled DHCP requests are not being forwarded by your
switches.
Function name:
Config
Function description:
The switch to enable clients to obtain IP addresses from a DHCP server on a
remote subnet, you have to configure the DHCP Relay Agent on the subnet that
contains the remote clients, so that it can relay DHCP broadcast messages to your
DHCP server.

3-4. IP-MAC Binding
The IP network layer uses a four-byte address. The Ethernet link layer uses a
six-byte MAC address. Binding these two address types together allows the
transmission of data between the layers. The primary purpose of IP-MAC binding is
to restrict the access to a switch to a number of authorized users. Only the
authorized client can access the Switch’s port by checking the pair of IP-MAC
Addresses and port number with the pre-configured database. If an unauthorized
user tries to access an IP-MAC binding enabled port, the system will block the
access by dropping its packet.
Function name:
IP MAC Binding Configuration
Function description:
The switch has client and server two classes of IP-MAC Binding table. The
maximum number of IP-MAC binding client table is 512 entries. The maximum

Four functions, including Port Status, Port Configuration, Simple Counter and
Detail Counter are contained in this function folder for port monitor and
management. Each of them will be described in detail orderly in the following
sections.
3-5-1.Port Status
The function Port Status gathers the information of all ports’ current status
and reports it by the order of port number, media, link status, port state, AutoNegotiation status, speed/duplex, Rx Pause and Tx Pause. An extra media type
information for the module ports 25 and 26 is also offered (See Fig. 3-11).
Fig. 3-13
Function name:

Publication date:March., 2011
Revision A1
Page 63
Port No:
Display the port number. The number is 1 – 26. Both port 25 and 26 are
optional modules.
Media:
Show the media type adopted in all ports. The Port 25 and Port 26 are
optional modules, which support either fiber or UTP media with either
Gigabit Ethernet (1000Mbps) or 10/100Mbps Fast Ethernet port. They
may have different media types and speed. Especially, fiber port has
comprehensive types of connector, distance, fiber mode and so on. The
switch describes the module ports with the following page.
Link:
Show that if the link on the port is active or not. If the link is 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.
State:
Show that the communication function of the port is “Enabled” or
“Disabled”. When it is enabled, traffic can be transmitted and received via
this port. When it is disabled, no traffic can be transferred through this
port. Port State is configured by user.
Auto Nego.:
Speed / Duplex :
Default: Enabled.
Show the exchange mode of Ethernet MAC. There are two modes
supported in the switch. They are auto-negotiation mode “Enabled” and
forced mode “Disabled”. When in “Enabled” mode, this function will
automatically negotiate by hardware itself and exchange each other the
capability of speed and duplex mode with other site which is linked, and
comes out the best communication way. When in “Disabled” mode, both
parties must have the same setting of speed and duplex, otherwise, both
of them will not be linked. In this case, the link result is “Down”.
Default: Enabled
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.
In port 1 – 24, they are supported Fast Ethernet with TP media only, so
the result will show 100M/Full or 100M/Half, 10M/Full and 10M/Half
duplex.

3-5-2. Port Configuration
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, Speed/Duplex and Flow Control.
Fig. 3-15
Parameter description:
54
Publication date:March., 2011
Revision A1
Page 67
State:
Set the communication capability of the port is Enabled or Disabled.
When enabled, traffic can be transmitted and received via this port.
When disabled, the port is blocked and no traffic can be transferred
through this port. Port State is configurable by the user. There are only
two states “Enable” and “Disable” able to choose. If you set a port’s state
“Disable”, then that port is prohibited to pass any traffic, even it looks
Link up.
Default: Enable.
Speed/Duplex:
Set the speed and duplex of the port. In speed, 10/100Mbps baud rate is
available for Fast Ethernet, Gigabit module in port 25, 26. 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.
Media type NWay Speed Duplex
100M TP ON/OFF 10/100M Full/Half
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 Symmetric and
Asymmetric. If flow control is set Symmetric, both parties can send
PAUSE frame to the transmitting device(s) if the receiving port is too
busy to handle. When it is set Asymmetric, this will let the receiving port
care the PAUSE frame from transmitting device(s), but it doesn’t send
PAUSE frame. This is one-way flow control.
Default: Symmetric.
Power Saving:
The parameter will enable or disable to verify switches have the ability to
consider the length of any Ethernet cable connected for adjustment of
power usage accordingly. Shorter lengths require less power. link-down
mode removes power for each port that does not have a device attached.
Default: Disable.

3-7. 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.
Fig. 3-19 Community and trap host setting
Parameters description:
SNMP:
The term SNMP here is used for the activation or de-activation of SNMP.
Default is Enable.
Get/Set/Trap Community:
62
Publication date:March., 2011
Revision A1
Page 75
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
Default community name for Trap: public
Default Set function : Enable
Default trap host IP address: 0.0.0.0
Default port number :162
Trap:
In the switch, there are 6 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.

3-8. 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”.

3-9. Multicast
The function, 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.
The packets will be discarded by the IGMP Snooping if the user transmits
multicast packets to the multicast group that had not been built up in advance.
3-9-1. IGMP Setting
Function name:
IGMP Setting
Function description:
IGMP is used to snoop the status of IP multicast groups and display its
associated information in both tagged VLAN and non-tagged VLAN networks.

by such protocols as RADIUS and DHCP for authentication and dynamic IP
allocation.
A lawful interception solution that analyzes RADIUS and DHCP for target IP
addresses will likely fail to intercept incoming multicast traffic to the target.

3-11. VLAN
The switch supports Tag-based VLAN (802.1q) and Port-based VLAN
Support 256 active VLANs and VLAN ID 1~4094. VLAN configuration is used to
partition your LAN into small ones as your demand. Properly configuring it, you can
gain not only improving security and increasing performance but greatly reducing
VLAN management.
3-11-1. VLAN Mode
Function name:
VLAN Mode Setting
Function description:
The VLAN Mode Selection function includes two modes: Port-based and Tagbased, you can choose one of them by pulling down list and pressing the
<Downward> arrow key. Then, click <Apply> button, the settings will take
effect immediately.
.
Parameter description:
VLAN Mode:
Tag-based:
This is the default setting.
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..
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.
Fig. 3-25

Publication date: Sep, 2009
Revision A8
Page 92
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.
Metro Mode:
The Metro Mode is a quick configuration VLAN environment
method on Port-based VLAN. It will create 22 or 23 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.
Up-link Port:
This function is enabled only when metro mode is chosen in VLAN mode.
25:
Except Port 25, each port of the switch cannot transmit packets with
each other. Each port groups a VLAN with Port 25, thus, total 23
groups consisting of 2 members are formed.
Page 93
26:
Except Port 26, each port of the switch cannot transmit packets with
each other. Each port groups a VLAN with Port 26, thus, total 23
groups consisting of 2 members are formed.
25&26:
Except Port 25 and Port 26, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port 25
and Port 26, thus, total 22 groups consisting of 3 members are
formed.

Function name:
Tag-based Group Configuration
Function description:
It shows the information of existed Tag-based VLAN Groups. You can also
easily create, edit and delete a Tag-based VLAN group by pressing <Add>,
<Edit> and <Delete> function buttons. User can add a new VLAN group by
inputting a new VLAN name and VLAN ID after pressing <Add> button.
Parameter description:
No:
To display current built-up tag base VLAN entry index
VLAN Name:
The name defined by administrator is associated with a VLAN group.
Valid letters are A-Z, a-z, 0-9, “ - “ and “_” 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.
GVRP Propagation:
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. You can configure
an individual port to actively or passively participate in dynamic VLAN
propagation or to ignore dynamic VLAN (GVRP) operation.

Member:
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.
Utag:
This is used to enable or disable if a port is a utag member of the new
added VLAN, “Enable” means it is a utag member of the VLAN. Just tick
the check box beside the port x to enable it.
Action:
The mode here means the type of participant. There are two modes,
Active and NotInService, provided for the user’s choice.
Active:
It is Active Participant. In this mode, the switch participates
active in GARP protocol exchanges. The default setting is
Active.
NotInService:
It is NotInService. In this mode, the switch does not send or
reply any GARP messages. It just listens messages and
reacts for the received GVRP BPDU.

3-11-3. PVID
Function name:
PVID
Function description:
In PVID 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 rule (Rule 2)
to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule
2 is enabled, the port will discard all Untagged-frames.
Parameter description:
Port 1-26:
Port number.
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:
It bases on 802.1p QoS and affects untagged packets. When the packets
enter the switch, it would get the priority precedence according to your
Default Priority setting and map to 802.1p priority setting in QoS function.
For example, while you set Default Priority of port 2 with 2 and transmit
untagged packets to port 2, these packets will own priority 2 precedence
due to your default 802.1p Priority Mapping setting in QoS function and
be put into Queue 1.
Fig. 3-29
Page 97
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
later is the case, only the packets carrying VLAN tag will be processed,
the rest packets will be discarded.
