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, MSS resets the STP counters for the specied ports or
VLANs to 0. The software then begins incrementing the counters again.
Spanning Tree Conguration Scenario
This scenario congures a VLAN named backbone for a switch’s connections to the
network backbone, adds ports 2 and 3 to the VLAN, and enables STP on the VLAN to
prevent loops.
1. Remove the network cables from ports 2 and 3 or use MSS to disable the ports. This
prevents a loop until you complete the STP conguration. To disable the ports and verify the
results, type the following commands:
DWS-1008# set port disable 2-3
success: set “disable” on port 2-3
