Reliability value on POS interface

[Ahmed Erfan Mehdi]

    Hello Expert,

I have faced a problem on POS interface,

these are two interfaces back to back details:    

POS at 7600 router:

sh int PO3/0/0

POS3/0/0 is up, line protocol is down

  Hardware is Packet over Sonet

  Description: STM4-To-1stCore-SH

  Internet address is 192.168.56.9/30

  MTU 4470 bytes, BW 622000 Kbit, DLY 100 usec,

     reliability 149/255, txload 1/255, rxload 1/255

  Encapsulation HDLC, crc 32, loopback not set

  Keepalive set (10 sec)

  Scramble disabled

  Last input 17:51:58, output 00:00:05, output hang never

  Last clearing of "show interface" counters 14:09:13

  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

  Queueing strategy: fifo

  Output queue: 0/40 (size/max)

  1 minute input rate 0 bits/sec, 0 packets/sec

  1 minute output rate 0 bits/sec, 0 packets/sec

     5061 packets input, 111294 bytes, 0 no buffer

     Received 0 broadcasts (0 IP multicasts)

     0 runts, 0 giants, 0 throttles

              0 parity

     9 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     0 packets output, 0 bytes, 0 underruns

     5096 output errors, 0 applique, 1 interface resets

     0 output buffer failures, 0 output buffers swapped out

     0 carrier transitions

POS at 12000 router:

POS0/2/3/0 is up, line protocol is down  (APS not Configured )

  Interface state transitions: 34

  Hardware is Packet over SONET/SDH

  Description: STM4-To-Permam

  MTU 4474 bytes, BW 622080 Kbit (Max: 622080 Kbit)

     reliability 255/255, txload 0/255, rxload 0/255

  Encapsulation HDLC, crc 32, controller loopback not set, keepalive set (10 sec)

  Last input 18:00:03, output 00:00:00

  Last clearing of "show interface" counters 14:53:18

  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 total input drops

     0 drops for unrecognized upper-level protocol

     Received 0 runts, 0 giants, 0 throttles, 0 parity

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     5586 packets output, 120936 bytes, 0 total output drops

     0 output errors, 0 underruns, 0 applique, 0 resets

     0 output buffer failures, 0 output buffers swapped out

Would you please help to identify this issue ? what about reliability value ?

Regards,

Ahmed

Ahmed,

Forget about the Reliability conter.

Your main kissue is that both ends are in a

UP/Down state.

Have a read at this link.

Chech framing, clocking and scrambling

Hello Acsmpbell,

thanks for replying ...

actuaaly i have reloaded the SIP itself and cleared counters then POS interface backed normally.

durning the reload operation i got this log message :

Dec 26 20:06:13 UTC: %SNMP-5-MODULETRAP: Module 3 [Down] Trap

Dec 26 20:06:13 UTC: %OIR-6-REMCARD: Card removed from slot 3, interfaces disabled

Dec 26 20:07:37 UTC: %DIAG-SP-6-DIAG_OK: Module 3/0: Passed Online Diagnostics

what powe log does means ?

Why POS interface went down suddenly ?

Thanks.
