Variable definitions

Use the data in the following table to use optional parameters with the show spanning-tree rstp port statistics command.


Variable	Value
`{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`	Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
