Description
Use this command to activate the timer for the BPDU guard feature. The
BPDU guard feature prevents unnecessary domain convergences by
disabling edge ports if they receive BPDUs. When the timer is activated,
the switch will automatically reactivate disabled ports. The time interval
that ports remain disabled is set with “SPANNING-TREE ERRDISABLE-
TIMEOUT INTERVAL” on page 674.
To disable the timer for the BPDU guard feature, use the NO SPANNING-
TREE ERRDISABLE TIMEOUT INTERVAL command.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 130
Example
The following example activates the timer for the BPDU guard feature:
