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 5000 Series NX-OS Security Configuration Guide for information about keychains.
This command requires an Enhanced Layer 2 license.

switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
