Configure Auto-sense IS-IS Authentication
Before you begin
Enable IS-IS globally.
About this task
Perform this procedure to configure a global IS-IS authentication key for ports that are operating in Auto-sense mode.
Note
If the IS-IS authentication keys on auto-sense ports between two switches do not match, then the auto-sense port state will be auto-sense UNI onboarding, until the keys are matching, then an IS-IS adjacency will be established.Procedure
Example
Configuring simple authentication for IS-IS hello packets on Auto-sense ports:
Switch:1>enable Switch:1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch:1(config)#auto-sense isis hello-auth type simple key Secure
Variable Definitions
The following table defines parameters for the auto-sense isis hello-auth type command.
