Configuration Tasks
Verifying Encapsulation
Use the show interfaces serial command to display the encapsulation method:
Router# show interfaces serial3/1/1
Serial3/1/1 is up, line protocol is down
Hardware is SPA-4XT-SERIAL
MTU 1500 bytes, BW 2016 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation FRAME-RELAY, crc 16, loopback not set
Keepalive set (10 sec)
LMI enq sent 13698, LMI stat recvd 0, LMI upd recvd 0, DTE LMI down
LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
LMI DLCI 1023 LMI type is CISCO frame relay DTE
FR SVC disabled, LAPF state down
Broadcast queue 0/64, broadcasts sent/dropped 0/0, interface broadcasts 0
Last input never, output 00:00:05, output hang never
Last clearing of "show interface" counters 1d14h
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicasts)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
19344 packets output, 254168 bytes, 0 underruns
0 output errors, 0 collisions, 2283 interface resets
0 output buffer failures, 0 output buffers swapped out
4566 carrier transitions
RTS up, CTS up, DTR up, DCD up, DSR up
Command Purpose
Router# configure terminal Enters global configuration mode.
Router(config)# interface serial slot/subslot/port Selects the interface to configure and enters
interface configuration mode.
• slot/subslot/port—Specifies the location of the
interface. See the
“Verifying the
Configuration” section on page 18-2.
Router(config-if)# encapsulation
encapsulation-type {hdlc | ppp | frame-relay}
Sets the encapsulation type on the interface.
• hdlc—High-Level Data Link Control (HDLC)
protocol for serial interface. This is the
default.
• ppp—Point-to-Point Protocol (PPP) (for
serial interface).
• frame-relay—Frame Relay (for serial
interface).
