bridge max-age
Use this command to set the maximum age for a bridge. This value is used by all instances.
Maximum 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. The value of maximum age should be greater than twice the value of hello time plus 1, but less than twice the value of forward delay minus 1. The allowable range for max-age is 6-40 seconds. Configure this value sufficiently high, so that a frame generated by root can be propagated to the leaf nodes without exceeding the maximum age.
Use the no parameter with this command to restore the default value of the maximum age.
Note: A Bridge shall enforce the following relationships for Hello-time, Max-age and Forward-delay.
• 2 × (Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age
• Bridge_Max_Age >= 2 × (Bridge_Hello_Time + 1.0 seconds)
