Configuring The Maximum Aging Time For A Vlan - Cisco Catalyst 4500 Series Configuration Manual

Configuring STP
To configure the spanning tree hello time of a VLAN, perform this task:
Command
Step 1
Switch(config)# [no] spanning-tree vlan vlan_ID
hello-time hello_time
Step 2
Switch(config)# end
Step 3
Switch# show spanning-tree vlan vlan_ID bridge
[brief]
This example shows how to configure the hello time for VLAN 200 to 7 seconds:
Switch# configure terminal
Switch(config)# spanning-tree vlan 200 hello-time 7
Switch(config)# end
Switch#
This example shows how to verify the configuration:
Switch# show spanning-tree vlan 200 bridge brief

Configuring the Maximum Aging Time for a VLAN

Note Exercise care when configuring aging time. In most cases, we recommend that you use the
spanning-tree vlan vlan_ID root primary and the spanning-tree vlan vlan_ID root secondary
commands to modify the maximum aging time.
To configure the spanning tree maximum aging time for a VLAN, perform this task:
Command
Step 1
Switch(config)# [no] spanning-tree vlan vlan_ID
max-age max_age
Step 2
Switch(config)# end
Step 3
Switch# show spanning-tree vlan vlan_ID bridge
[brief]
This example shows how to configure the maximum aging time for VLAN 200 to 36 seconds:
Switch# configure terminal
Switch(config)# spanning-tree vlan 200 max-age 36
Switch(config)# end
Switch#
