[H/W] Cisco CRC and Input Errors ProblemHello Experts,
Our WAN interface is experiencing a large amount input errors and output errors, see below. Of particular notice is the fact the input errors are identical to the CRCs.
Serial0/0/0:0 is up, line protocol is up Hardware is GT96K Serial Description: BT MPLS 1BRACGNL.0394 MTU 1500 bytes, BW 1986 Kbit/sec, DLY 20000 usec, reliability 251/255, txload 30/255, rxload 7/255 Encapsulation FRAME-RELAY IETF, loopback not set Keepalive set (10 sec) LMI enq sent 1139, LMI stat recvd 1138, LMI upd recvd 0, DTE LMI up LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0 LMI DLCI 0 LMI type is ANSI Annex D frame relay DTE FR SVC disabled, LAPF state down Broadcast queue 0/64, broadcasts sent/dropped 0/0, interface broadcasts 0 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 03:09:43 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 209 Queueing strategy: Class-based queueing Output queue: 0/1000/64/209 (size/max total/threshold/drops) Conversations 0/96/256 (active/max active/max total) Reserved Conversations 1/1 (allocated/max allocated) Available Bandwidth 717 kilobits/sec 5 minute input rate 60000 bits/sec, 44 packets/sec 5 minute output rate 235000 bits/sec, 52 packets/sec 468880 packets input, 125910744 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 318 input errors, 318 CRC, 116 frame, 33 overrun, 0 ignored, 203 abort 592137 packets output, 471008276 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 unknown protocol drops 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions Timeslot(s) Used:1-31, SCC: 0, Transmitter delay is 0 flags
My initial thoughts are the problem is with the service provider. However, because the input errors are identical I'm not sure it the problem is with the provider?
Any help will be appreciated..
Cheers
