Configuration Tasks
Verifying the Interface Configuration
Use the show interface serial command to verify the interface configuration:
Router# show interface serial 1/0/0.1/1:0
Serial1/0/0.1/1:0 is up, line protocol is up
Hardware is SPA-1XCHSTM1/OC3
Internet address is 10.1.1.1/16
MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive not set
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/375/0/0 (size/max/drops/flushes); Total output drops: 0
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
Step 5
Router(config-controller)#
framing {bypass | g751 | g832}
Sets the framing on the interface, where:
• bypass—Configures framing bypass to use the full E3
bandwidth.
• g751— Specifies g751 framing. This is the default for E3.
• g832—Specifies g832 framing.
Step 6
Router(config-controller)# crc
{16 | 32}
Selects the CRC size in bits, where:
• 16—16-bit CRC. This is the default
• 32—32-bit CRC.
Step 7
Router(config-controller)#
loopback {network | local |
remote}
Specifies loopback is enabled for the unchannelized E3 serial
interface, where:
• local loopback—Loops data from the transmit path to the
receive path.
• network loopback—Loops data received on the external
port to the transmit path and back out the external port.
• remote loopback—Sends a far-end alarm control request to
the remote end requesting that it enter into a network line
loopback.
Step 8
Router(config-controller)#
shutdown
Shuts down the E3 interface.
Step 9
Router(config-controller)# bert
pattern pattern interval 1-14400
Sends a BERT pattern on an E3 line, where:
• pattern—Specifies the length of the repeating BERT test
pattern. Allowed values are 2^15, 2^20, 2^23, 0s, 1s, and
alt-0-1.
• interval time—Specifies the duration of the BERT test, in
minutes. The interval can be a value from 1 to 14400.
