2. Installation
2-1. Starting 8 Fast Ethernet + 2 Gigabit L2 Managed Switch Up
This section will give users a quick start for:
- Hardware and Cable Installation
- Management Station Installation
- Software booting and configuration
2-1-1. Hardware and Cable Installation
At the beginning, please do first:
⇒ Wear a grounding device to avoid the damage from electrostatic discharge
• Installing Optional SFP Fiber Transceivers to the L2 Managed Switch
Note: If you have no modules, please skip this section.
• Connecting the SFP Module to the Chassis:
The optional SFP modules are hot swappable, so you can plug or unplug it
before or after powering on.
1. Verify that the SFP module is the right model and conforms to the
chassis
2. Slide the module along the slot. Also be sure that the module is properly
seated against the slot socket/connector
Fig. 2-1 Installation of Optional SFP Fiber Transceive

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 pi n-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. Installing Chassis to a 19-Inch Wiring Closet Rail
Fig. 2-2
Caution: Allow a proper spacing and proper air ventilation for the cooling fan
at both sides of the chassis.
⇒ Wear a grounding device for electrostatic discharge.
⇒ Screw the mounting accessory to the front side of the switch (See Fig. 2-2).
⇒ 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.
⎯ Gigabit Fiber with multi-mode LC SFP module
⎯ Gigabit Fiber with single-mode LC SFP module
⎯ Gigabit Fiber with BiDi LC 1310nm SFP module
⎯ Gigabit Fiber with BiDi LC 1550nm SFP module
The following table lists the types of fiber that we support and those else not
listed here are available upon request.

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
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.

each other (See Fig. 2-3).
Fig. 2-3 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.2-4).

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.

Normally, it just uses pins 2, 3 and 7. See also Appendix B for more
details on Null Modem Cable Specifications.
2. Attaches the DB-9 female cable connector to the male serial RS-232
DB-9 connector on the switch.
3. Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial
port, running a terminal emulator supporting VT100/ANSI terminal with
The switch’s serial port default settings. For example,
Windows98/2000/XP HyperTerminal utility.
Note: The switch’s serial port default settings are listed as follows:

• Set IP Add ress, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-7 CLI 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 the 8 Fast Ethernet + 2 Gigabit L2 Managed Switch 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.

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.

Signamax™ 065-7710 8-Port 10/100BaseT/TX + 2SFP Managed Switch
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

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.

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 belo w:
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 t he network itself, and all 1s mean IP broadcast.

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

/29 8 6

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.

Signamax™ 065-7710 8-Port 10/100BaseT/TX + 2SFP Managed Switch
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 switch through
the web user interface it supports, to access and manage the 8 10/100Mbps TP + 2
Gigabit dual media ports with TP/SFP Fiber management Ethernet switch. With this
facility, you can easily access and monitor through any one port of the switch all the
status of the switch, including MIBs status, each port activity, Spanning tree status,
port aggregation status, multicast traffic, VLAN and priority status, even illegal
access record and so on.
The default values of the managed switch are listed in the table below:
IP Address
Subnet Mask
Default Gateway
Username
Password
192.168.1.1
255.255.255.0
192.168.1.254
admin
admin
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
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 .

In the switch, it supports a simple user management function allowing only
one administrator to configure the system at the same time. If there are two or more
users using administrator’s identity, the switch will allow the only one who logins first
to configure the system. The rest of users, even with administrator’s identity, can
only monitor the system. For those who have no administrator’s identity, can only
monitor the system. There are only a maximum of three users able to login
simultaneously in the switch.
To optimize the display effect, we recommend you use Microsoft IE 6.0
above, Netscape V7.1 above or FireFox V1.00 above and have the resolution
1024x768. The switch supported neutral web bro wser interface.

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.
Fig. 3-4 IP Address Configuration
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.
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
Network ID
Host ID
Network ID Host ID
Subnet number
Subnet mask is used to set the subnet mask value, which should be the
same value as that of the other devices resided in the same network it
attaches.
For more information, please also see the Section 2-1-5 “IP Address
Assignment” in this manual.
Default: 255.255.255.0
Default gateway:
Set an IP address for a gateway to handle those packets that do not
meet the routing rules predefined in the device. If a packet does not meet
the criteria for other pre-defined path, it must be forwarded to a default
router on a default path. This means any packet with undefined IP
address in the routing table will be sent to this device unconditionally.
Default: 192.168.1.254

DNS:
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.
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
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.
Parameter description:
Current Time:
RFC 1305,
Show the current time of the system.
Manual:
This is the function to adjust the time manually. Filling the valid figures in
the fields of Year, Month, Day, Hour, Minute and Second respectively and
press <Apply> button, time is adjusted. The valid figures for the
parameter Year, Month, Day, Hour, Minute and Second are >=2000, 1-12,
1-31, 0-23, 0-59 and 0-59 respectively. Input the wrong figure and press
<Apply> button, the device will reject the time adjustment request. There
is no time zone setting in Manual mode.
Default: Year = 2000, Month = 1, Day = 1
Hour = 0, Minute = 0, Second = 0

NTP:
NTP is Network Time Protocol and is used to sync the network time
based Greenwich Mean Time (GMT). If use the NTP mode and select a
built-in NTP time server or manually specify an user-defined NTP server
as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically,
NTP does not update the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone
first and then perform time sync via NTP because the switch will combine
this time zone offset and updated NTP time to come out the local time,
otherwise, you will not able to get the correct time. The switch supports
configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
Daylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time
lag or in advance in unit of hours, according 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
Saving and described in detail.

Function description:
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.
Parameter description:

3-1-6. Virtual Stack
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_065-7710), 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 .

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.

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.

Default community name for GET: public
Default community name for SET: private
Default community name for Tra p: 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.

3-4. 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.
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.

Function name:
IGMP Snooping Status
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.
Enabling IGMP with either passive or active mode, you can monitor the IGMP
snooping information, which contains the multicast member list with the
multicast groups, VID and member port.

IGMP snooping mode selection:
The switch supports three kinds of IGMP Snooping status, including
“Passive”, “Active” and “Disable”.
Disable:
Set “Disable” mode to disable IGMP Snooping function.
Default: Disable
Active:
In Active mode, IGMP snooping switch will periodically issue the
Membership Query message to all hosts attached to it and
gather the Membership report message to update the database
of the Multicast table. By the way, this also reduces the
unnecessary multicast traffic.
Passive:
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.
IP Address:
Show all multicast groups IP addresses that are registered on this device.
VLAN ID:
Show VLAN ID for each multicast group.
Member Port:
Show member ports that join each multicast group. Member port may be
only or more than one.

3-6. 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.
3-6-1. 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.
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.

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.
Fig. 3-23
Parameter description:
Port 1-10:
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.

3-8. GVRP Configuration
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.
In GVRP Configuration function folder, there are three functions supported,
including GVRP Config, GVRP Counter and GVRP Group explained below.

3-9. STP Configuration
The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D)
for avoiding loops in switched networks. When STP is enabled, ensure that only
one path is active between any two nodes on the network at a time. User can
enable Spanning Tree Protocol on switch’s web management and then set up other
advanced items. We recommend that you enable STP on all switches to ensure a
single active path on the network.
3-9-1. STP Status
Function name:
STP Status
Function description:
In the Spanning Tree Status, user can read 12 parameters to know STP
current status. The 12 parameters’ description is listed in the following table.
Parameter description:
STP S tate:
Show the current STP Enabled / Disabled status. Default is “Disabled”.
Bridge ID:
Show switch’s bridge ID which stands for the MAC addres s of this switch.
Bridge Priority:
Show this switch’s current bridge priority setting. Default is 3276 8.
Designated Root:
Show root bridge ID of this network segment. If this switch is a root
bridge, the “Designated Root” will show this switch’s bridge ID.
Designated Priority:
Show the current root bridge priority.
Root Port:
Show port number connected to root bridge with the lowest path cost.
Root Path Cost:
Show the path cost between the root port and the designated port of the
root bridge.
Current Max. Age:
Show the current root bridge maximum age time. Maximum age time is
used to monitor if STP topology needs to change. When a bridge does
not receive a hello message from root bridge until the maximum age time
is counted down to 0, the bridge will treat the root bridge malfunctioned
and issue a Topology Change Notification (TCN) BPDU to all other
bridges.

Signamax™ 065-7710 8-Port 10/100BaseT/TX + 2SFP Managed Switch
All bridges in the LAN will re-learn and determine which the root bridge is.
Maximum Age time is assigned by root bridge in unit of seconds. Default
is 20 seconds.
Current Forward Delay:
Show the current root bridge forward delay time. The value of Forward
Delay time is set by root. The Forward Delay time is defined as the time
spent from Listening state moved to Learning state or from Learning
state moved to Forwarding state of a port in bridge.
Hello Time:
Show the current hello time of the root bridge. Hello time is a time
interval specified by root bridge, used to request all other bridges
periodically sending hello message every “hello time” seconds to the
bridge attached to its designated port.
STP Topology Change Count:
STP Topology Change Count expresses the time spent in unit of seconds
since the beginning of the Spanning Tree Topology Change to the end of
the STP convergence. Once the STP change is converged, the Topology
Change count will be reset to 0. The figures showing in the screen may
not be the exact time it spent but very close to, because the time is
eclipsing.
Time Since Last Topology Change:
Time Since Last Topology Change is the accumulated time in unit of
seconds the STP has been since the last STP Topology Change was
made. When Topology Change is initiated again, this counter will be
reset to 0. And it will also count again once STP topology Change is
completed.

3-9-2. STP Configuration
The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning
Tree Configuration, there are six parameters open for the user to configure as
user’s idea. Each parameter description is listed below.
Function name:
STP Configuration
Function description:
User can set the following Spanning Tree parameters to control STP function
enable/disable, select mode RSTP/STP and affect STP state machine
behavior to send BPDU in this switch. The default setting of Spanning Tree
Protocol is “Disable”.
Parameter description:
Spanni ng 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
065-7710 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
065-7710 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 065-7710 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).

3-9-3. STP Port Configuration
Function name:
STP Port Setting
Function description:
In the STP Port Setting, one item selection and five parameters settings are
offered for user’s setup. User can disable and enable each port by selecting
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 p ackets
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 contrib ute its learning
knowledge but cannot forward packets still.
FORWARDING state indicates this port can both contribute its learning
knowledge and forward packets norma lly.
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)
10 Mbps : 2,000,000
100 Mbps : 200,000
1 Gbps : 20,000
Default: 0
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.
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.
Default: Auto
