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 interface FortyGigE 1/0/1.
<Sysname> system-view [Sysname] interface fortygige 1/0/1 [Sysname-FortyGigE1/0/1] spbm authentication send-only
