Usage guidelines
An interface sends keepalive packets at keepalive intervals to detect the availability of the peer. If the
interface fails to receive keepalive packets when the keepalive retry limit is reached, it considers the
link faulty and reports a link layer down event.
To set the keepalive interval, use the
timer-hold
command.
On a slow link, increase the keepalive retry limit to prevent false shutdown of the interface. This
situation might occur when keepalive packets are delayed because a large packet is being
transmitted on the link.
Examples
# Set the keepalive retry limit to 10 for Serial 2/1/0.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] timer-hold retry 10
