Parameters

interface-type interface-number: Displays information for a specified IS-IS interface. If you do not specify this argument, the command displays information about all interfaces.

verbose: Displays detailed information about an interface. If you do not specify this keyword, the command displays brief information about an interface.

statistics: Displays IS-IS interface statistics.

process-id: Displays IS-IS interface information for an IS-IS process specified by its ID in the range of 1 to 65535. If you do not specify this argument, the command displays interface information for all IS-IS processes.
