internal spanning tree (CIST), and the maximum value of instance-id is 15.

interface interface-list: Displays the spanning tree information on one or multiple 
ports. You can provide up to 10 port lists, by each of which you can specify an 
individual port in the form of interface-type interface-number, or a port range in 
the form of interface-type start-interface-number to interface-type 
end-interface-number, where the end port number must be greater than the start 
port number.
