Dear All,
I've installed E1 card (VWIC3-4MFT-T1/E1) in cisco 2911 router (IOS version 15.4) and configured accordingly. But Link Status of serial interfaces
down. Here is the Card configuration and Sh interface serial 0/0/0:0 commands result-
Card Configuration:
Step:1
=====================================
card type e1 0 0
card type e1 0 1
Fast Card Interface Configuration
===================================
controller E1 0/0/0
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/0/1
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/0/2
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/0/3
framing NO-CRC4
channel-group 0 timeslots 1-31
Second Card interface configuration
============================================
controller E1 0/1/0
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/1/1
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/1/2
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 0/1/3
framing NO-CRC4
channel-group 0 timeslots 1-31
And here is the serial interface status:
sh interfaces serial 0/0/0:0
Serial0/0/0:0 is down, line protocol is down
Hardware is DSX1
MTU 1500 bytes, BW 1984 Kbit/sec, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (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
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 2 interface resets
0 unknown protocol drops
0 output buffer failures, 0 output buffers swapped out
1 carrier transitions
So what is the problem and how can i up the link status?
