Description

Display IS-IS hostname database information.

This command displays the system ID-to-name cache. The output shows if the mapping has been learned by receipt of a Hostname TLV #137 (type dynamic) configured in Junos OS with the set system host-name command, or a static mapping defined in Junos OS with the set system static-host-mapping hostname sysid command (type static). The local router always has its type set to static even if static-host-mapping is not configured.

Options

none	Display IS-IS hostname database information.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on a particular logical system.
