388 Configuring and managing spanning tree protocolNN47250-500 (320657-F Version 02.01)Clearing STP statisticsTo 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. Thesoftware then begins incrementing the counters again.Spanning tree configuration scenarioThis scenario configures a VLAN named backbone for a WSS’s connections to the network backbone, adds ports 21 and22 to the VLAN, and enables STP on the VLAN to prevent loops.1 Remove the network cables from ports 21 and 22 or use WSS Software to disable the ports,. This preventsa loop until you complete the STP configuration. To disable the ports and verify the results, type thefollowing commands:WSS# set port disable 21-22success: set "disable" on port 21-22WSS# show port statusPort Name Admin Oper Config Actual Type Media===============================================================================1 up up auto 100/full network 10/100BaseTx2 up down auto network 10/100BaseTx3 up down auto network 10/100BaseTx4 up down auto network 10/100BaseTx5 up down auto network 10/100BaseTx6 up down auto network 10/100BaseTx7 up down auto network 10/100BaseTx8 up down auto network 10/100BaseTx9 up down auto network 10/100BaseTx10 up down auto network 10/100BaseTx11 up down auto network 10/100BaseTx12 up down auto network 10/100BaseTx13 up down auto network 10/100BaseTx14 up down auto network 10/100BaseTx15 up down auto network 10/100BaseTx16 up down auto network 10/100BaseTx17 up down auto network 10/100BaseTx18 up down auto network 10/100BaseTx19 up down auto network 10/100BaseTx20 up down auto network 10/100BaseTx21 down down auto network22 down down auto network2 Configure a backbone VLAN and verify the configuration change.
