return to the default configuration.
Usage
Guidelines
When configuring the maximum age, the max-age setting must be greater than the hello-time
setting. The following relationship should be kept:
2*(forward-delay - 1)>=max-age>=2*(hello-time + 1)
Examples
To configure the maximum-age to 10 seconds:
switch(conf-rstp)#max-age 10
