Nortel Networks 2300 manual Spanning Tree Configuration Scenario, Clearing STP Statistics

332Configuring and Managing Spanning Tree Protocol

Clearing STP Statistics

To clear the STP statistics counters, use the following command.

clear spantree statistics port-list[vlan vlan-id]

As soon as you enter the command, WSS Software resets the STP counters for the specified ports or VLANs to 0. The software then begins incrementing the counters again.

Spanning Tree Configuration Scenario

This scenario configures a VLAN named backbone for an WSS switch's connections to the network backbone, adds ports 21 and 22 to the VLAN, and enables STP on the VLAN to prevent loops.

1Remove the network cables from ports 21 and 22 or use WSS Software to disable the ports,. This prevents a loop until you complete the STP configuration. To disable the ports and verify the results, type the following commands:

23x0# set port disable 21-22

success: set "disable" on port 21-22

23x0# show port status
