Parameters

seconds: Specifies an interval in the range of 3 to 255 seconds.

Usage guidelines

ISIS-SPB sends hellos over links to establish and maintain adjacencies between SPBM nodes.

A short interval improves network convergence time, but it requires more system resources.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the original hello interval remains unchanged.

Examples

# Set the ISIS-SPB hello interval to 20 seconds on FortyGigE 1/0/1.

<Sysname> system-view
[Sysname] interface fortygige 1/0/1
[Sysname-FortyGigE1/0/1] spbm timer hello 20
