Usage Guidelines

IS-IS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

Output

The show isis neighbors command displays the following information:


Output field	Description
Total number of IS-IS Neighbors	The number of ISs with which the device has formed IS-IS adjacencies.
System ID	The System ID of the neighbor or the hostname of the neighbor.
Interface	The device port or virtual interface attached to the neighbor.
SNPA	The Subnetwork Point of Attachment (SNPA), which is the MAC address of the device port or virtual interface attached to the neighbor.
State	The state of the adjacency with the neighbor. The state can be one of the following: DOWN - The adjacency is down. INIT - The adjacency is being established and is not up yet. UP - The adjacency is up.
Holdtime	The neighbor‘s advertised hold time.
Type	The IS-IS type of the adjacency. The type can be one of the following: ISL1 - Level-1 IS ISL2 - Level-2 IS ES - ES Note: The device forms a separate adjacency for each IS-IS type. Thus, if the device has both types of IS-IS adjacencies with the neighbor, the display contains a separate row of information for each adjacency.
Pri	The priority of this IS to be elected as the Designated IS in this broadcast network.
StateChgeTime	The amount of time that has passed since the adjacency last changed state.
Protocol	The routing protocol supported by the neighbor. The protocol can be one of the following: MT-ISIS - Multi-Topology is enabled on the neighbor. ISIS - Multi-Topology is not enabled on the neighbor.

3-Way Handshake TLV received	The received 3-way handshake TLV for the interface.
Area Address (es)	The address of the area.
Protocols Supported	The topology supported by the neighbor.
IP Address	The IP address assigned to the neighbor interface.
Adj Usage L1	The adjacency level used by the neighbor.
circuit ID	The ID of the IS-IS circuit running on the neighbor interface.
Protocol	The routing protocol supported by the neighbor. The protocol can be one of the following: MT-ISIS - Multi-Topology is enabled on the neighbor. ISIS- Multi-Topology is not enabled on the neighbor.
