link-keepalive interval

Enables the interval time that UDLD sends health-check packets.
Syntax
link-keepalive interval time
no link-keepalive interval time
Command Default

By default, ports enabled for UDLD send a health-check packet once every 500 milliseconds (ms).

Parameters
time

Specifies the time that UDLD sends the health-check packets, in milliseconds. You can specify from 1 through 60, in 100 ms increments (1 is 100 ms, 2 is 200 ms, and so on). The default is 5 (500 ms).

Modes

Global configuration mode

Usage Guidelines

A low UDLD link-keepalive interval is not recommended because low UDLD link-keepalive intervals are more sensitive and prone to flaps.

The no form of the command resets the interval to the default value.

Examples

The following example shows the UDLD interval configuration.

device(config)# link-keepalive interval 4
