Description This command specifies the interval, in seconds, used to send periodic keepalive packets. The receiver pro-
cess 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 "timeout interval". The link is declared up once the
number of continual keepalive packets received equals to the up-count. The nodes at the two endpoints of
the cHDLC link should be provisioned with the same values.
Default 10
Parameters time-interval — Specifies the interval used to send periodic keepalive packets.
