Configure IS-IS Interface Level Parameters

Use the following procedure to configure IS-IS interface level parameters. SPBM uses IS-IS to discover network topology, build shortest path trees between network nodes, and communicate network information in the control plane.

Procedure

In the navigation pane, expand Configuration > Fabric.
Select IS-IS.
Select the Interfaces Level tab.
Configure the IS-IS interface level parameters.
Optional: Select the Remote button to configure the remote IS-IS interface level parameters.

Note

This step only applies to the VSP 7400 Series.
Select Apply.

Interfaces Level Field Descriptions

Use the data in the following table to use the Interfaces Level tab.


Name	Description
Index	The identifier of this circuit, unique within the Intermediate System. This value is for SNMP Indexing purposes only and need not have any relation to any protocol value.
Level	Specifies the router type globally: l1: Level1 router type l12: Level1/Level2 router type. This type is not supported. The default value is l1.
ISPriority	Specifies an integer sub-range for IS-IS priority. The default is 64.
HelloTimer	Configures the level 1 hello interval. Specifies the maximum period, in milliseconds, between IS-IS Hello Packets (IIH) PDUs on multiaccess networks at this level for LANs. The value at Level1 is used as the period between Hellos on Level1/Level2 point to point circuits. Setting this value at Level 2 on an Level1/Level2 point-to-point circuit results in an error of InconsistentValue. The default value is 9000 milliseconds or 9 seconds.
HelloMultiplier	Configures the level 1 hello multiplier. The default value is 3 seconds.
DRHelloTimer	Indicates the period, in milliseconds, between Hello PDUs on multiaccess networks when this Intermediate System is the Designated Intermediate System. The default is 3.
