What to Do Next
• To modify the default Frame Relay configuration on serial interfaces that have Frame Relay
encapsulation enabled, see the “Modifying the Default Frame Relay Configuration on an Interface”
section of the “Configuring Frame Relay on the Cisco ASR 9000 Series Router” module in this
manual.
Modifying the Keepalive Interval on Serial Interfaces
Perform this task to modify the keepalive interval on serial interfaces that have Cisco HDLC or PPP
encapsulation enabled.
Note When you enable Cisco HDLC or PPP encapsulation on a serial interface, the default keepalive interval
is 10 seconds. Use this procedure to modify that default keepalive interval.
Step 7
configure
interface serial interface-path-id.subinterface
pvc dlci
encap [cisco | ietf]
commit
Example:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router (config)# interface
serial 0/1/0/1.1
RP/0/0RP0RSP0/CPU0:router (config-subif)# pvc

RP/0/0RP0RSP0/CPU0:router (config-fr-vc)# encap

RP/0/0RP0RSP0/CPU0:router (config-fr-vc)#
commit
Repeat Step 1 through Step 6 to bring up the serial
subinterface and any associated PVC at the other end of the
connection.
Note The configuration on both ends of the subinterface
connection must match.
Step 8
show frame-relay pvc dlci-number
Example:
RP/0/0RP0RSP0/CPU0:router# show frame-relay pvc
20
(Optional) Verifies the configuration of specified serial
interface.
Step 9
show policy-map interface serial
interface-path-id.subinterface {input | output}
or
show policy-map type qos interface serial
interface-path-id.subinterface {input | output}
Example:
RP/0/0RP0RSP0/CPU0:router# show policy-map
interface serial 0/1/0/0.1 output
or
RP/0/0RP0RSP0/CPU0:router# show policy-map type
qos interface serial 0/1/0/0.1 output
(Optional) Displays the statistics and the configurations of
the input and output policies that are attached to a
subinterface.
