Configuring Serial Interfaces on the Cisco ASR 9000 Series Router

The following example shows how to configure the interval between keepalive messages to be 10
seconds:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/3/0/0/0:0
RP/0/0RP0RSP0/CPU0:router(config-if)# keepalive 10
RP/0/0RP0RSP0/CPU0:router(config-if)# commit
The following example shows how to modify the optional serial interface parameters:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/3/0/0/0:0
RP/0/0RP0RSP0/CPU0:Router(config-if)# serial
RP/0/0RP0RSP0/CPU0:Router(config-if-serial)# crc 16
RP/0/0RP0RSP0/CPU0:Router(config-if-serial)# invert
RP/0/0RP0RSP0/CPU0:Router(config-if-serial)# scramble
RP/0/0RP0RSP0/CPU0:Router(config-if-serial)# transmit-delay 3
RP/0/0RP0RSP0/CPU0:Router(config-if-serial)# commit
The following is sample output from the show interfaces serial command:
RP/0/0RP0RSP0/CPU0:Router# show interfaces serial 0/0/3/0/5:23
Serial0/0/3/0/5:23 is down, line protocol is down
Hardware is Serial network interface(s)
Internet address is Unknown
MTU 1504 bytes, BW 64 Kbit
Encapsulation HDLC, crc 16,
Last clearing of "show interface" counters 18:11:15
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
Configuring a Serial Interface with Frame Relay Encapsulation: Example
The following example shows how to create a serial interface on a SPA with Frame Relay encapsulation
and a serial subinterface with a PVC on router 1:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/1/0/0
RP/0/0RP0RSP0/CPU0:router(config-if)# encapsulation frame-relay
RP/0/0RP0RSP0/CPU0:router(config-if)#frame-relay intf-type dce
RP/0/0RP0RSP0/CPU0:router(config-if)# no shutdown
RP/0/0RP0RSP0/CPU0:router(config-if)# end
Uncommitted changes found, commit them? [yes]: yes
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/1/0/0.1 point-to-point
