spanning-tree vlan forward-time
Use this command to configure the spanning tree forward delay time for a VLAN or a set of VLANs. The
default is 15 seconds.
Set this value to a lower number to accelerate the transition to forwarding. The network operator should
take into account the end-to-end BPDU propagation delay, the maximum frame lifetime, the maximum
transmission halt delay, and the message age overestimate values specific to their network when
configuring this parameter.
