Max Age

Maximum aging time is the number of seconds a switch waits without receiving spanning-
tree configuration messages before attempting a reconfiguration.
To configure the maximum aging time for deleting useless messages, use the following
command.
Command
spanning-tree mst max-age <6-
40>
spanning-tree vlan VLANS max-
age <6-40>
We recommend that the maximum aging time is set less than twice of forward delay time
and more than twice of hello time.
To delete a configured maximum aging time, use the following command.
Command
no spanning-tree mst max-age
no spanning-tree vlan VLANS
max-age

VLANS: VLAN ID (1-4094)
6-40: maximum aging time value (default: 20 sec)
Mode
Returns to the default maximum aging time value of
MSTP.
