VLAN. This procedure is optional.
To return to the default setting, use the no spanning-tree vlan vlan-id forward-time global
configuration command.
Configuring the Maximum-Aging Time for a VLAN
Beginning in privileged EXEC mode, follow these steps to configure the maximum-aging time for a
VLAN. This procedure is optional.
To return to the default setting, use the no spanning-tree vlan vlan-id max-age global configuration
command.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 spanning-tree vlan vlan-id forward-time
