Hi
what is the best process for see where is the probleme ?
i have a Cisco 7204 with NPE225, a PA-E3 and:
C7204#sh interface Serial2/0 Serial2/0 is down, line protocol is down Hardware is M1T-E3 pa Internet address is 172.20.2.221/30 MTU 4470 bytes, BW 34010 Kbit, DLY 200 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, crc 16, loopback not set Keepalive set (10 sec) Restart-Delay is 0 secs Last input 2d05h, output 2d05h, output hang never Last clearing of "show interface" counters 3d00h 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 24 packets input, 1379 bytes, 0 no buffer Received 8 broadcasts (0 IP multicasts) 0 runts, 0 giants, 0 throttles 0 parity 1 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 1 abort 36 packets output, 2746 bytes, 0 underruns 0 output errors, 0 applique, 7 interface resets 0 output buffer failures, 0 output buffers swapped out 13 carrier transitions rxLOS inactive, rxLOF inactive, rxAIS active txAIS inactive, rxRAI inactive, txRAI active
the second 7204, same configuration, the serial are Up but protocol are down, but i see
C7204-2#sh interfaces serial 1/0 Serial1/0 is up, line protocol is down Hardware is M1T-E3 pa Internet address is 172.20.2.222/30 MTU 4470 bytes, BW 34010 Kbit, DLY 200 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, crc 16, loopback not set Keepalive set (10 sec) Restart-Delay is 0 secs Last input never, output 00:00:02, output hang never Last clearing of "show interface" counters 2d23h 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 runts, 0 giants, 0 throttles 0 parity 18 input errors, 18 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 25916 packets output, 626716 bytes, 0 underruns 0 output errors, 0 applique, 9 interface resets 0 output buffer failures, 0 output buffers swapped out 19 carrier transitions rxLOS inactive, rxLOF inactive, rxAIS inactive txAIS inactive, rxRAI active, txRAI inactive
he lost line are not same, on the first router, i have AIS in red
thanks for your help
