## Configure the Maximum Hop Count

The max hop count is the maximum number of hops the BPDU can traverse before getting discarded and also before the information held for a port is aged out.

1. Configure the maximum hop count.

       SEFOS# configure terminal
       SEFOS(config)# spanning-tree mst max-hops 10

   The maximum hop range is 6-40. The default is 20.

       SEFOS(config)# end

2. View the MST port-specific configuration.

       SEFOS# show spanning-tree mst detail
