When you configure PPP over ATM or Multilink PPP over ATM encapsulation, you
can enable or disable keepalives on the logical interface. For more information, see
"Configuring PPP over ATM2 Encapsulation" on page 342.
To explicitly enable the sending of keepalives on a physical interface, include the
keepalives statement at the

keepalives;
To change one or more of the default keepalive values, include the appropriate option
at the [edit interfaces interface-name]

keepalives <interval seconds> <down-count number> <up-count number>;
On interfaces configured with Cisco HDLC or PPP encapsulation, you can include
the following three keepalive statements; note that Frame Relay encapsulation is not
affected by these statements:
—The time in seconds between successive keepalive requests.
interval seconds
The range is from 1 second through 32767 seconds, with a default of 10 seconds.
down-count number —The number of keepalive packets a destination must fail to
receive before the network takes a link down. The range is from 1 through 255,
with a default of 3.
—The number of keepalive packets a destination must receive
up-count number
to change a link s status from down to up. The range is from 1 through 255, with
a default of 1.
WARNING: If interface keepalives are configured on an interface that does not support
the configuration statement (for example, 10-Gigabit Ethernet), the link
keepalives
layer may go down when the PIC is restarted. Avoid configuring the keepalives on
interfaces that do not support the
