Configuring Spanning Tree MSTP Configurations
Step 5 spanning-tree max-hops value
(Optional) Specify the maximum BPDU hop counts that can be forwarded in a MST region. A
switch receives BPDU, then decrements the hop count by one and generates BPDUs with the
new value. When the hop reaches zero, the switch will discard the BPDU. This value can control
the scale of the spanning tree in the MST region.
value: Specify the maximum number of hops that occur in a specific region before the BPDU is
discarded. The valid values are from 1 to 40 in hop, and the default value is 20.
Step 6 show spanning-tree bridge
(Optional) View the global parameters of the switch.
Step 7 end
Return to privileged EXEC mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
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
