SPANNING-TREE MAX-AGE
Syntax
spanning-tree max-age <6-40>
no spanning-tree max-age
Parameters
none
Description
Use the SPANNING-TREE MAX-AGE command to set the max-age for a
bridge. Max-age is the maximum time, in seconds, for which (if a bridge is
the root bridge) a message is considered valid. This prevents the frames
from looping indefinitely. This value is used by all instances.
Set the value of max-age to greater than twice the value of hello time plus
one, but less than twice the value of forward delay minus one. The
allowable range for max-age is 6-40 seconds. The default value is 20
seconds.
Configure this value sufficiently high, so that a frame generated by root
can be propagated to the leaf nodes without exceeding the max-age.
Use the no form of this command to restore the default value of max-age.
Command Mode
Configuration Terminal mode
Example
The following commands set the max-age time for the bridge to 10
seconds:
switch#configure terminal
switch(config)#spanning-tree max-age 10
