spanning-tree mac-flush-timer
Enables or disables MAC flush optimization.
Syntax
spanning-tree mac-flush-timer timer-interval
Parameters timer-interval—Enter the timer interval in centi-seconds, from 0 to 500. The default value is 200
milli-seconds.
Default Enabled
Command Mode CONFIGURATION
Usage
Information
This command configures the flush interval time in centi-seconds, and controls the number of calls
invoked from the spanning-tree module. If the timer is set to 0, MAC flush optimization is disabled. If the
timer is set to a non-zero value, instance-based flushing occurs based on the MAC flush threshold value.
The no version of this command resets the flush-interval timer to the default value.
Example
OS10(config)# spanning-tree mac-flush-timer 500
OS10(config)# no spanning-tree mac-flush-timer
Supported
