## Configure Timers

This example specifies that the port changes from blocking to forwarding state in 11 seconds.

       SEFOS# configure terminal
       SEFOS(config)# spanning-tree forward-time 11
       SEFOS(config)# end

2. View the spanning tree properties of an interface.

       SEFOS# show spanning-tree
