Parameters
seconds: Specifies the interval at which the interface sends keepalive packets. The value range for this
argument is 0 to 32767 seconds.
Usage guidelines
On an interface encapsulated with PPP or HDLC, the data link layer sends keepalive packets at keepalive
intervals to detect the availability of the remote end. The data link layer considers the peer end as having
failed if it does not receive any keepalive messages within a specific number of keepalive intervals. The
data link layer then reports the link down event to the upper layer protocols.
On a slow link, increase the keepalive interval 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 interval to 15 seconds for POS 2/2/0.
