5. (Optional) copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 config t
Example:
switch# config t
switch(config)#
Step 2 spanning-tree mst forward-time seconds
Example:
switch(config)# spanning-tree mst
forward-time 10
Step 3 exit
Example:
switch(config)# exit
switch#
Step 4
show spanning-tree mst
Example:
switch# show spanning-tree mst
Step 5 copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
This example shows how to configure the forward-delay time of the device to 10 seconds:
switch# config t
switch(config)# spanning-time mst forward-time 10
switch(config)# exit
switch#
Purpose
Enters global configuration mode.
Configures the forward time for all MST instances. The
forward 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.
Exits global configuration mode.
(Optional)
Displays the MST configuration.
(Optional)
Copies the running configuration to the startup configuration.
