Configure IS-IS Interfaces

Use the following procedure to configure the IS-IS interfaces. 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 > IS-IS.
Select IS-IS.
Select the Interfaces tab.
Configure the IS-IS interface parameters.
Select Apply.

Interfaces field descriptions

Use the data in the following table to use the Interfaces 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.
IfIndex	Specifies the interface on which the circuit is configured (port or MLT).
Type	Specifies the IS-IS circuit type. Only the point-to-point (PtToPt) interface type is supported.
AdminState	Specifies the administrative state of the circuit: on or off.
OperState	Specifies the operational state of the circuit.
AuthType	Specifies the authentication type: none simple: If selected, you must also specify a key value but the key id is optional. Simple password authentication uses a text password in the transmitted packet. The receiving router uses an authentication key (password) to verify the packet. hmac-md5: If selected, you must also specify a key value, but the key-id is optional. MD5 authentication creates an encoded checksum in the transmitted packet. The receiving router uses an authentication key (password) to verify the MD5 checksum of the packet. There is an optional key ID. hmac-sha–256: If selected, you must also specify a key value, but the key-id is optional. With SHA-256 authentication, the switch adds an hmac-sha–256 digest to each Hello packet. The switch that receives the Hello packet computes the digest of the packet and compares it with the received digest. If the digests match, the packet is accepted. If the digests do not match, the receiving switch discards the packet. There is an optional key ID. Note: Secure Hashing Algorithm 256 bits (SHA-256) is a cipher and a cryptographic hash function of SHA2 authentication. You can use SHA-256 to authenticate IS-IS Hello messages. This authentication method uses the SHA-256 hash function and a secret key to establish a secure connection between switches that share the same key. This feature is in full compliance with RFC 5310. The default is none.
AuthKey	Specifies the authentication key.
KeyId	Specifies the authentication key ID.
LevelType	Specifies the router type globally: level1: Level-1 router type level 1and2: Level–1/2 router type. This type is not supported. The default value is level1.
NumAdj	Specifies the number of adjacencies on this circuit.
NumUpAdj	Specifies the number of adjacencies that are up.
AutoNniEnable	Enable to have the node create an IS-IS interface, attach the interface to an SPBM instance, and then enable IS-IS on the port interface. This field displays on the Insert Interfaces dialog box and applies to port interfaces only.
Origin Note: Exception: not supported on VSP 8600 Series and XA1400 Series.	Specifies the origin of the IS-IS circuit configuration on the port, either manually configured through CLI or EDM or dynamically configured through Auto-sense.
