Description Use this command to clear the spanning-tree counters on the interface.

Usage Guidelines If the interface parameter is not specified, spanning-tree counters are cleared for all interfaces.

If xSTP is enabled over VCS, this command must be executed on all RBridge nodes.

Examples To clear spanning-tree counters for all interfaces:

switch# clear spanning-tree counter

To clear spanning-tree counters for a 10-gigabit Ethernet interface:

switch# clear spanning-tree counter interface tengigabitethernet 0/1

To clear spanning-tree counters for port-channel 23:

switch# clear spanning-tree counter interface port-channel 23
