Management Methods

The 24 Port SNMP Managed Switch supports following management methods:

• Console and Telnet Management

• Web-based Management

• SNMP Network Management

Console and Telnet Management

Console Management is done through the RS-232 Console Port. Managing the 24 Port

SNMP Managed Switch in this method requires a direct connection between PC and the 24

Port SNMP Managed Switch. While Telnet management is done over the network. Once the

24 Port SNMP Managed Switch is on the network, you can use Telnet to log in and change

the configuration. The automatic log-out times can be programmed and are detailed on pages

36 and 56. See page 12 for details.

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 38 for details.

SNMP Network Management

SNMP (Simple Network Management Protocol) provides a means to monitor and control a

network device, and to manage configurations, statistic collection, performance and security.

Data is passed from SNMP agents, which are hardware & software processes reporting

activity in each network device to the workstation console used to oversee the network. The

agent returns information contained in a MIB (Management Information Base), which is a data

structure that defines what is obtainable from the device and what can be controlled.

Quick Start Guide

If you do not need to apply VLANs, Quality of Service, 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 completed and AC power is applied to the switch, the unit will

automatically perform a diagnostic test. The switch loads its operating code from memory

and performs a full power-on self test. The screen will display the self-test progress, but

do not press any keys at this stage. This power-up sequence takes approx. 90 seconds to

complete. The web interface will take a further 30 seconds to become operational.

2. Configure you 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. Set the emulation program for 9600, 8, No Parity, No Flow Control. See

page 12 for details

3. When the password and user name prompt is displayed, use the default username of

root in lower case letters. Use the password root. The main menu screen will be

displayed. Use either cursor keys or the tab key to navigate up and down the menu.

Select the item using the <CR> key. The <ESC> key will return you to the previous menu

level.

4. If the switch is to be managed over the LAN using the Telnet, SNMP or the web browser

functions, then an IP address is to be assigned to the switch. See page 14 for details. If

the switch is not being managed over the LAN, then go to page 12 below.

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. See page …. For details.

6. Now that the switch can be accessed over the network, use a browser application to open

up the configuration screens. Enter the switch IP address into the browser Address

window 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 your network 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 36

or page 55.

Switch Device Configuration Menu

Figure 17. The Switch Device Configuration Menu

This menu sets numerous key functions and modes for the entire switch. It is recommended

that the required modes are set using this menu before attempting to configure port details.

24 Port SNMP Managed Switch – User Manual Page 19

The Switch Device Configuration menu options are listed below. Use the <space> bar to

toggle modes, or enter time values directly:-

• The Spanning Tree Protocol for the switch is enabled or disabled in this menu.

• The Dynamic Ageing Time is the number of seconds that an entry will be stored in

the switch ARL table before it is aged out. The default is 300 seconds, but in some

test applications, it may be desirable to reduce this time.

• Ingress filtering when enabled the switch will reject all tagged VLAN traffic not

intended for the port that is receiving the tagged packet.

• The Per Port Priority control allows the ports to be allocated specific priority values

from the Switch Port Configuration menu.

• The HOLB Prevention control either enables or disables Head Of Line Blocking. This

is an advanced function associated with egress flow control and heavily loaded

networks where it is desirable to constrain the use of switch buffers to protect other

ports. It is recommended that this control is left in the <enabled> state for normal

network applications.

• When QoS (Quality of Service) is enabled you can map the Type of Service of your

choice (according to IEEE 802.1p) to the four priority levels provided.

• The switch supports three different VLAN modes:-

o Port Based VLAN,

o IEEE 802.1Q VLAN

o MTU/MDU VLAN.

The choice made here will ultimately decide the VLAN mode and function for the entire

switch. See Below for VLAN description.

• The GVRP Enable State allows structured and centralized VLAN registration in multi-

switch networks, To enable this function, use the <space> bar to toggle the

enable/disable mode.

• The IGMP Snooping mode is used for multicast environments where the switch

participates in multicast operations. To enable this function, use the <space> bar to

toggle the enable/disable mode.

• The IGMP Snoop Table Ageing time sets the timeout for multicasts. Enter the value

directly into this field.

Port Based VLAN

This mode is the simplest form of VLAN and is intended where basic VLANs on a single

switch are required. This mode allows specified physical ports on the switch to be grouped

into single collision domains to prevent any traffic from other domains entering that zone. An

example is where the Engineering workstations must not be allowed to access the HR

network area. The security of Port Based VLANs is limited and dependant on the physical

security of the switch and its connections. The IEEE802.1Q tag attribute is ignored by Port

Based VLANs .

IEEE 802.1Q VLAN

This is a more common form of enterprise VLAN where traffic is tagged with a VLAN identifier,

which specifies which groups can receive the traffic. Each packet is tagged with a VLAN ID

number and the switch makes decisions on the logical groupings of these VLAN Ids. For

example, Engineering may be assigned VLANID 20, Sales assigned VLAN ID 30 and HR

assigned VLAN ID 40.

MTU/MDU VLAN

This mode is typically used in fiber-to-the-home applications where it is desirable to place

each physical switch port into a different VLAN for security purposes.

24 Port SNMP Managed Switch – User Manual Page 20

Switch Port Configuration

Figure 18. The Switch Port Configuration Menu

This menu is used to select and then configure the required ports. The first element

highlighted in the menu is the Group ID. The switch is divided into 3 groups:-

• A = Ports 1-12,

• B = Ports 13-24,

• C = The 2 option slots (ports 25 and 26).

Use the <space> key to toggle between the different port groups. Alternatively, you can move

to different groups by using the Prev Page and Next Page fields at the bottom of the screen.

Highlight the required switch port by using the <Tab> or cursor key to move through the port

list of the selected group. Select the port by using the <CR> or Return key. This action opens

a new sub-menu that allows the specified port to be configured.
