Usage guidelines

Before you change adjacency authentication settings on a link, configure this command to prevent temporary authentication setting mismatch from causing loss of adjacencies.

For security purposes, restore the default to authenticate incoming ISIS-SPB hello packets after you change adjacency authentication settings on the link.

This command does not affect outgoing ISIS-SPB hello packets. When adjacency authentication is enabled, outgoing ISIS-SPB hello packets always contain authentication information.

Examples

# Disable authentication for incoming ISIS-SPB hello packets on HundredGigE 1/0/1.

<Sysname> system-view
[Sysname] interface hundredgige 1/0/1
[Sysname-HundredGigE1/0/1] spbm authentication send-only
