through in a MSTP region before being discarded. This parameter takes effect
for all instances.
To configure the Maximum-Hop Count, execute the following commands in the
global configuraiton mode:
Command Function
DES-7200# configure terminal
Enter the global configuration mode.
DES-7200(config)# spanning-tree
max-hops hop-count
Configure the Maximum-Hop Count
ranging from 1 to 40, 20 by default.
DES-7200(config)# end
Return to the privileged EXEC mode.
DES-7200# show running-config
Verify the configuration.
DES-7200# copy running-config
startup-config
Save the configuration.
To restore the Maxium-Hop Count to the default value, execute the no
spanning-tree max-hops command in the global configuration mode.

Command Function
DES-7200# configure terminal
Enter the global configuration mode.
