authentication key-chain (FabricPath)

To configure an authentication keychain between FabricPath devices, use the authentication key-chain command. To return to the default setting, use the no form of this command.

authentication key-chain auth-key-chain-name

Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

Use the authentication key-chain command to assign a password in the authentication of a hello protocol data unit. Only one authentication key-chain is applied to an IS-IS interface at one time. If you configure a second authentication command, the first is overridden. You can specify authentication for an entire instance of IS-IS instead of at the interface level by using the authentication command.

See the Cisco Nexus Security Configuration Guide for your platform for information about keychains.

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to configure an authentication keychain string for edge device authentication:

switch# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
switch(config)# fabricpath domain default
switch(config-fabricpath-isis)# authentication key-chain fabrickeys
switch(config-fabricpath-isis)#
