Parameter Description Value
process-id

Specifies the ID of an IS-IS process.

The value is an integer ranging from 1 to 4294967295.

If no IS-IS process is specified, information about interfaces in all local IS-IS processes is displayed.

no-peer

Displays information about IS-IS interfaces that are Up but have no neighbors.

-

vpn-instance vpn-instance-name

Specifies the VPN instance to which an IS-IS process belongs.

Usage Guidelines

Usage Scenario

To check information about IS-IS interfaces, including the interface name, IP address, link status of each interface, run the display isis interface command. If verbose is specified, the output of this command also covers IS-IS parameter configurations for each interface, such as the CSNP broadcast interval, hello packet broadcast interval, and the number of IS-IS Hello packets sent by the neighbor before IS-IS should declare the neighbor Down.

Example

The actual command output varies according to the device. The command output here is only an example.
