Configuring Spanning Tree MSTP Configurations

Note:
To prevent frequent network flapping, make sure that Hello Time, Forward Delay, and Max Age
conform to the following formulas:
•
2*(Hello Time + 1) <= Max Age
•
2*(Forward Delay - 1) >= Max Age
This example shows how to configure the CIST priority as 36864, the Forward Delay as 12
seconds, the Hold Count as 8 and the Max Hop as 25:
Switch#configure
Switch(config)#spanning-tree priority 36864
Switch(config-if)#spanning-tree timer forward-time 12
Switch(config-if)#spanning-tree hold-count 8
Switch(config-if)#spanning-tree max-hops 25
Switch(config-if)#show spanning-tree bridge
State Mode Priority Hello-Time Fwd-Time Max-Age Hold-Count Max-Hops

function globally:
Step 1 configure
Enter global configuration mode.
Step 2 spanning-tree mode mstp
Configure the spanning tree mode as MSTP.
mstp:
Specify the spanning tree mode as MSTP.
Step 3 spanning-tree
Enable spanning tree function globally.
Step 4 show spanning-tree active
