View IS-IS Adjacencies
Use the following procedure to display IS-IS adjacency information. The platform sends IS-IS Hello (IIH) packets to discover IS-IS neighbors and establish and maintain IS-IS adjacencies. The platform continues to send IIH packets to maintain the established adjacencies. For two nodes to form an adjacency the B-VLAN pairs for the primary B-VLAN and secondary B-VLAN must match.
Procedure
- In the navigation pane, expand .
- Select IS-IS.
- Select the Adjacency tab.
Adjacency Field Descriptions
Use the data in the following table to use the Adjacency tab.
|
Name |
Description |
|---|---|
|
Interface |
Specifies the IS-IS interface on which the adjacency is found. |
|
Level |
Indicates the level of the IS-IS interface (Level 1 [default] or Level 2). |
|
State |
Specifies the state of the adjacency:
|
|
LastUpTime |
Indicates when the adjacency most recently entered the state up, measured in hundredths of a second since the last re-initialization of the network management subsystem. Displays 0 if the adjacency has never been in state up. |
|
NeighPriority |
Specifies the priority of the neighboring Intermediate System for becoming the Designated Intermediate System. |
|
HoldTimer |
Specifies the holding time in seconds for this adjacency. This value is based on received IS-IS Hello (IIH) PDUs and the elapsed time since receipt. |
|
NeighSysID |
Specifies the system ID of the neighboring Intermediate System. |
|
AdjHostName |
Specifies the host name listed in the LSP, or the IS-IS system name. The IS-IS system name uses global system name, if host name is not configured. |
|
ParallelActive |
Specifies if the current adjacency among all the parallel adjacencies between two nodes is active. On VSP 4900 Series and VSP 7400 Series only, this field also indicates if the adjacency is a backup |
