Step 2 switch(config)# spanning-tree mst Configures the forward time for all MST instances. The

forward-timesecondsforward delay is the number of seconds that a port waits before changing from its spanning tree blocking and learning states to the forwarding state. For seconds, the range is from 4 to 30, and the default is 15 seconds.

This example shows how to configure the forward-delay time of the switch to 10 seconds:

switch# configure terminal

switch(config)# spanning-tree mst forward-time 10
