Cabletron Systems ELH100 Configuring Port Operation, Spanning Tree, Setting a Default Gateway

Configuring Port Operation

You can configure 10/100 ports on the base unit for operational parameters such as enabled/disabled, and port speed or auto-sensing.

To configure port operation, do the following:

1.Select Port Configuration from the Main Menu.

2.Select Administrative Status Control from the Port Configuration menu.

3.Select Port Group 1-12, 13-24 or Switch/Media Module.

4.Highlight any port, and select “Enabled” or “Disabled” in the Admin State field to toggle between enabling and disabling the port(s).

5.Select “Force 10,” “Force 100” or “Auto” under the Mode field to set the port speed to 10 Mbps, 100 Mbps or auto-detection.

The console interface can only enable/disable the ports on switch/media modules. To configure the speed/mode, use the 100Full/Auto toggle switch on the 10Base-T/100Base-TX module or the Full/Half toggle switch on the 100Base-FX module.

Spanning Tree

The Switch/Media modules do not support Spanning Tree, which is intended to prevent network loops from forming. There is no loop detection.

The user is cautioned to understand and avoid configurations that can create a loop. However, if the ELH100-12/24TX is connected in a redundant link configuration to a single device which does support Spanning Tree, one link will be properly blocked, preventing a network loop from forming. This method can be used to provide a standby connection to the network backbone which will become active if the primary link is lost.

Setting a Default Gateway

The Default Gateway parameter defines the IP address of a router or other network device which is on the same subnet as the hub. The gateway receives IP packets that are to be sent to another subnet.

To set a default gateway, do the following:

1.Select System Configuration Menu from the Main Menu.

3.Enter the gateway IP address under New Setting. Select <APPLY>.
