Description This command configures the interval, in seconds, used to send periodic keepalive packets.
The receiver process expects to receive a keepalive packet every keepalive interval. The link
is declared down if the receiver process does not receive a keepalive within the time-out
interval. The link is declared up when the number of continual keepalive packets received
equals the up-count. The nodes at the two endpoints of the cHDLC link must be provisioned
with the same values.
The no form of this command returns the keepalive interval to the default value.
Default 10
Parameters time-interval — sets the interval, in seconds, used to send periodic keepalive packets
Values 0 to 300. A value of 0 means no keepalive packets are sent.
