The 24 Port Stackable Managed Switch supports the following management methods:
•
•
•
Console and Telnet Management
Web-based Management
SNMP Network Management
Console and Telnet Management
Console Management is performed through the RS-232 Console Port. Managing the 24
Stackable Managed Switch using this method requires a direct connection between a PC and
the 24 Port Stackable Managed Switch. Telnet allows remote management of the Switch
across the network. Once the 24 Port Stackable Managed Switch is on the network with an
assigned IP address, it is possible to use Telnet to log in and change the configuration.
Web Based Management
The Switch can be managed using a standard web browser that supports Java applets. This
interface has the same functionality as the console/Telnet interfaces but is more user-friendly.
See page 42 for details.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means to monitor and control the
Switch. Agents, which reside in the Switch, respond to requests from the NMS (Network
Management Station). The agent returns information contained in a MIB (Management
Information Base), which is a data structure that defines what is obtainable from the Switch
and what can be controlled.

Connecting to the Switch
The Console port is a male DB-9 connector located on the front panel of the Switch that
enables a connection to a PC or terminal for monitoring and configuration. Use the supplied
RS-232 cable with a female DB-9 connector to connect a terminal or PC to the Console port.
Figure 8. Connecting the 24 Port Stackable Managed Switch to a terminal via
RS-232 cable
Quick Start Guide
If you do not need to apply VLANS, Quality of Service, Stacking functionality, adjust any
settings or manage the Switch via the network, then the Switch can be used “straight-from-
the-box” to carry network traffic. In that case, no further action is needed. If you want to use
the management settings or controls, then a little work is needed to configure the Switch.
1. After the installation is complete and AC power is applied, the Switch loads its
operating code from memory and performs a full power-on self test that takes about
30 seconds to complete.
2. Configure the PC terminal emulation program, such as HyperTerminal, to allow it to
communicate with the Switch via the supplied serial cable connected to the front
panel Console port. See page11 for details
3. After configuring the emulation program press <enter> and input root in lower case
letters for both the User Name and Password. The main menu screen will be
displayed. Use either <tab> or cursor keys to navigate up and down the menu. Select
the item using the <enter> key. The <esc> key will return to the previous menu level.
4. If the Switch is to be managed over the network using Telnet, SNMP or the web
browser, then an IP address needs to be assigned to the Switch. See page 18 for
details.
5. Once an IP address has been assigned to the Switch, it should be possible to PING
the Switch over the network. This will prove that the Switch is present and responding
correctly to network requests.
6. Now that the Switch can be accessed over the network, use a web browser
application to open up the configuration screens. Enter the Switch’s IP address into
the web browser URL field and use the same user name and password set as in 3
above.
7. Using the preferred method (console, Telnet or web browser), configure the Switch to
meet the requirements. Always save the configuration at the end of each action.
8. If you need to revert the Switch back to the factory default configuration, then see
page 41.

IEEE802.1Q VLANS
This is a more complex form of VLAN that reacts to the tagging field in the Ethernet packets.
Unlike Port Based VLANS, where VLANS created are only significant to the local Switch,
802.1Q VLANS can exist across multiple Switches. The connection between these Switches
is called an 802.1Q trunk.
Figure 25. 802.1Q VLAN Configure Screen
1. Having selected 802.1Q in the VLAN Configure Menu the above is displayed.
2. Use the <tab> to move into the VLAN ID Range and select required VLAN ID range
by pressing <space>. Again using the <tab> key to move into the port field of the
menu. Enter the number of the tagged VLAN ID directly into the VLAN ID field. If the
device connected to this port does not support tagged VLANS, the ingress traffic will
have the specified default tag number added to each packet. This allows legacy
devices that do not support tagging to interoperate with tagged VLAN systems.
3. Use the <tab> key to move into the Ingress Filter field of the menu. Use the
<spacebar> to toggle between Disable and Enable. When this filter is Enable
(default), then only ingress packets with an identical VLAN tag to the port VLAN ID
will be forwarded. If Disable, all tagged packets will be forwarded.
4. Use the <tab> key to move into the Acceptable Frame Type field of the menu. Use
the <spacebar> key to toggle between All and Tag Only. If All then all tagged and

MAC Address Configuration
This menu section is selected from the Switch Configuration menu screen and enables
configuration of the static or filtered MAC addresses. These settings are only needed for
certain security operations and are not generally used. It is also possible from this option to
view MAC addresses that have been learnt by the Switch.
In some instances, it is necessary to manually apply a fixed or static address into the tables of
the Switch. When you add a static MAC address, it remains in the Switch's address table,
regardless of whether the device is physically connected to the Switch. This saves the Switch
from having to learn a device's MAC address.
Static MAC Address
From the MAC Address Configuration menu select the option Static MAC Address. A new
menu is displayed listing the existing static MAC addresses. Select <add> from the action
line. A new menu is displayed that requests the MAC address value and the physical port that
is associated with the static address value. If VLANS are configured it will also request a
VLAN ID. When these values have been entered, use the <esc> key to return to the action
line and then select the <apply> to ensure that the MAC values are stored. The menu will
display each static MAC address configured, the associated port and VLAN ID.
Filtering MAC Address
There maybe times when filtering packets based on the destination MAC address is needed.
This is achieved using Filtering MAC Address menu, selected from the MAC Address
Configuration menu. After selecting this option a new menu is displayed listing the current
MAC addresses that are being filtered and their associated VLAN ID. Select <add> from the
action line. A new menu is displayed that requests the MAC address value to be filtered and if
VLANS are configured, the VLAN ID value. When these values have been entered, use the
<esc> key to return to the action line and then select <apply> to ensure the configuration is
saved.
All MAC Addresses
There can be occasions when it is useful to determine what MAC addresses have been learnt
on a port for troubleshooting reasons. Select All MAC Addresses from the MAC
Configuration Menu. Now choose <select> from the action line and use the <spacebar> to
list port number options. Select the port to be viewed by pressing <enter>. A new screen is
now displayed showing a list of MAC addresses that have been learnt on this port, and their
associated VLANID. The Status field shows if the MAC address is Dynamic (learnt) or Static.
NOTE: This option currently only works on a Standalone or Master Switch

Misc Configuration
This menu is selected from the Switch Configuration menu screen and enables configuration
of the remaining Switch-specific variables such as MAC Ageing time, Broadcast Storm,
Stacking mode etc.
Figure 29. Misc Configuration Screen
MAC Address Aging Time
This setting specifies the time that a dynamic MAC address can remain in the Switch tables
before the value is “aged out”. The valid range is 300 to 765 seconds. The default value is
300 seconds, which is the industry standard duration. This value rarely needs to be modified.
Broadcast Storm Filter
This is used to limit the number of packets flowing through the Switch that do not have
associated entries in the Switch tables (Destination Look-Up Failures) or excessive broadcast
transmissions. In some instances, this high level of DLF/broadcast traffic can degrade
network performance. To minimize this problem, the Switch can be programmed to limit the
amount of broadcast traffic that can flow through the Switch. In normal networks, only a few
percent of traffic would normally be broadcasts.
This mode is accessed from the Misc. Configuration screen and is changed by selecting
<edit> from the action line and then using <tab> key for navigation to Broadcast Storm field.
Use the <spacebar> to step through the valid thresholds:
•
•
•
•
•
•
N/A (Disabled)
5%
10%
15%
20%

Max Bridge Transmit Delay Bound
This control is used in association with QoS Configuration to control the time that packets
may be queued in the Switch. If the packet is stored in the Switch for a time exceeding the
specified amount, then it is dropped. These settings do not need to be changed except for
networks where time-sensitive prioritized traffic is used. The default is OFF.
Low Queue Delay Bound
If low priority packets are queued in the Switch for longer than the ‘Low Queue Max Delay
Time’, then the Switch will forward the packet immediately. Default is Disable.
NOTE: Ensure that ‘Max Bridge Transmit Delay Bound’ is ON before enabling ‘Low Queue
Delay Bound’.
Low Queue Max Delay Time
Defines the maximum time a low priority packet will be queued before being sent. The valid
range is 1 to 255ms. The default max delay time is 255ms.
Collisions Retry Forever
In the default enable state the Switch will attempt to send a packet forever in the event of
collisions. If disabled the Switch will re-transmit the packet up to 48 times in the event of
collisions and after this the packet will be dropped.
Hash Algorithm
This controls the method used to maintain the MAC table. Either CRC Hash or Direct Hash.
The default is CRC Hash.
IFG Compensation
When enabled Inter-Frame Gap is forced to 0.96 microseconds. This maintains compatibility
with LAN cards and other network equipment. If disabled then the IFG remains unchanged.
The default is enabled.
IP Stacking Group ID
Assigns the stacking group ID, which is used to control stack membership. Switches
belonging to the same stack must be assigned the same stacking group ID. The valid range is
0 to 65535).
IP Stacking Mode
There are three stacking modes that can be configured on the Switch:
•
•
Disable – The Switch is not participating in a stack and is standalone (default)
Master – The Switch is the main controller Switch in the stack. There can be only one
configured Master in the stack.
•
Slave – All other Switches in the stack are configured as Slaves. Web management
of these Slave Switches is preformed via the Master Switch.
IP Stacking System Information
This is a meaningful name that can be given to the Switch e.g. Sales Switch – rack 4, that is
displayed when using a web browser to manage the Switch.
Please refer to page 42 for further details about Stacking.

is now enabled on the Switch.
System Configuration
This screen provides both information and configuration of the spanning tree protocol. Useful
information such as Root Bridge, Root Port and cost to root can be gathered from here. The
following parameters can also be changed from this menu:
•
•
Priority – This parameter allows the control of Root Bridge in the STP network. The
lower the priority, the more likely this Switch will be elected as root. The valid range
is 1 - 65535.
Max Age - The number of seconds the Switch waits for hello messages from root
bridge before deciding the root is unavailable and performing a reconfiguration. The
valid range is 6 - 40.
•
•
Hello Time – This is the interval in time (seconds) that a root bridge sends BPDU
configuration messages. The valid range is 1 - 10.
Forward Delay Time – The period in time (seconds) a Switch will wait (the listen
and learn period) before forwarding frames. The valid range is 4 - 30.
Per Port Setting
This screen allows the individual RSTP/STP values to be set on the required ports. . A port
with higher priority, lower path cost is less likely to be blocked if Spanning Tree Protocol
detects a network loop. The following can be configured:
•
Path Cost – This parameter can be used to assign a higher or lower path cost to a
port. A port with a high path cost is more likely to be blocked. The valid range is 1 -
200000000.
•
•
Priority – If path cost to root is equal then a port with a higher priority (lower
numerical value) is more likely to forward traffic. The valid range is 1 - 240.
P2P – This parameter is used by RSTP to determine if the port is connected to a
shared or full-duplex link, which will affect RSTP state transaction. It is
recommended to keep this parameter with the default of Auto.
•
•
Edge – This is a RSTP value. A port directly connected to end stations cannot
create a bridging loop. The default is true.
Non STP – The status shown here indicates if the port is participating in STP.
Per Port Status
This is informational screen only and parameters cannot be changed. The STP status
of each port can be viewed. The following STP port statuses are:
•
•
•
•
•
•
Role – indicates the STP role of the port
State – determines the STP state of the port
Path Cost – The port cost.
P2P – The current P2P status of the port
Edge – The current Edge status of the port

IP Stacking
The Switch can be web managed in either a standalone or stacking mode. In stacking mode a
group of Switches (8 maximum) can be managed using a single IP address from a web
browser, which simplifies the management task. One Switch in the Stack is configured as the
‘Master’ Switch and all other Switches are configured as a ‘Slave’. Switches belonging to the
same Stacking group must have the same IP Stacking Group ID.
Note: After configuring an IP Stacking Group. Slave Switches can only be managed through
the Master Switch. It is not possible to Web/Telnet/SNMP Manage a Slave Switch directly.
IP Stacking Configuration
1. Select the IP Configuration menu on each Switch and assign a unique IP address to
all Switches that are to be stacked (NOTE: Only the Master Switch’s IP address is
used on the LAN. All other IP addresses assigned to Slave Switches can be reused
for other devices on the LAN. Ensure that assigned IP addresses are in the same
subnet.
2. To enable one Switch as Master, select Misc Configuration from Switch Configuration
menu and modify:
IP Stacking Group ID – Choose a unique ID, between 0 - 65535, to identify the
stacking group
IP Stacking Mode – Select this Switch to be Master
IP Stacking System Information – Give the Switch a meaningful name that will be
displayed when web managed.
Save the configuration
3. The next task is to configure all other Switches as Slaves. Select Misc Configuration
on each Switch and modify:
IP Stacking Group ID – Configure each Switch with the same ID as the Master.
IP Stacking Mode – Select each Switch to be ‘Slave’
IP Stacking System Information – Give each Switch a meaningful name that will be
displayed when web managed.
Save the configuration
4. Now ensure all Switches are connected to the LAN and are in the same broadcast
domain (subnet). It is recommended that the Switches be directly connected to each
other.

The Stack will remain manageable if the Master Switch fails or looses network connectivity. If
this should happen then the BackupMaster will go active and maintain the manageability of
the Stack. The BackupMaster is elected by the lowest MAC address in the Stack and no user
configuration is needed. The IP Stacking screen (Figure 40.) is used to determine the current
Master and BackupMaster Switch.
NOTE: The IP address used to manage the Stack, after the Master Switch fails, remains
unchanged.

Web Based Management
Inside the Switch exists an embedded web server that allows administrators to manage the
Switch remotely. The Web Based management is a graphical interface, which some users
may find easier and more intuitive than other management methods.
The Web-Based Management supports Microsoft Internet Explorer 5.0 and above (plus other
web browsers). It is based on Java Applets with an aim to reduce network bandwidth
consumption, enhance access speed and present an easy viewing screen.
Configuring The Switch for Web Based Management
The Switch has the following default values that need to be adjusted to suit your network:
IP Address:
10.10.10.10
255.255.255.0
10.10.10.254
root
Subnet Mask:
Default Gateway:
User Name:
Password:
root
1.
2.
Obtain the correct local IP addresses from your network administrator and enter the
values from the console menu as detailed on page 17. This IP information has to be
entered via the console, as the web interface will not be accessible until the local IP
address values have been entered, saved and the Switch restarted.
After the Switch has been restarted with the new IP address, check that the Switch is
visible on the network by ‘pinging’ the address. If the Switch is present and correctly
configured, then the ‘ping’ will echo back a response message otherwise the message
“Request Timeout” will be displayed. Ensure that the Switch can be ‘pinged’ before
proceeding. Consult your system administrator for details of ‘pinging’. The syntax from
your PC is:
Start >Run> ping 162.109.37.13 –t
Where the 162.109.37.13 is the example IP address allocated to the Switch
The –t causes the ping test to run continuously.
3.
After the ‘ping’ test has passed, open a web browser window (such as Microsoft Internet
Explorer) and enter the allocated IP address of the Switch into the URL field. For
example:
If all the settings are correct, then the browser will display a user name and password
box similar to the one below:

to the password box and enter the default password root. If the settings are correct,
then the browser will begin to render a new page showing the image of the Switch. This
is the home page of the Switch web management screen.
Figure 42. Web Browser Home Page Screen
It is recommended that you explore the menu bar in the left hand side of the screen. This
menu area controls the configuration, control and statistics elements of the Switch.

Port Status Screen
The most basic and useful menu is the read-only Port Status screen, which provides the
current status of each port.
Figure 43. Port Status Screen
This menu screen displays the read-only link status (Up/Down) of all ports together with the
Auto-negotiation mode, duplex mode and flow control settings. A ‘green’ port on the graphical
representation of the Switch also indicates the link status of a port that is UP. The
programmable port values can be changed in the Administrator > Port Controls Screen.
