Greetings All, I'm getting CRC errors on one of my serial interfaces: #sh int Serial0/0/0:1 Serial0/0/0:1 is up, line protocol is up Hardware is Serial Description: DHEC.800936.811.ATI MTU 1500 bytes, BW 1536 Kbit/sec, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 21/255 Encapsulation PPP, LCP Open, multilink Open Link is a member of Multilink bundle Multilink1, loopback not set Keepalive set (10 sec) Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 17:20:42 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: weighted fair [suspended, using FIFO] FIFO output queue 0/40, 0 drops 5 minute input rate 132000 bits/sec, 18 packets/sec 5 minute output rate 9000 bits/sec, 11 packets/sec 756027 packets input, 733579767 bytes, 0 no buffer Received 0 broadcasts (0 IP multicasts) 2123 runts, 0 giants, 0 throttles 2660 input errors, 532 CRC, 0 frame, 0 overrun, 0 ignored, 5 abort 508136 packets output, 77127054 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:1-24, SCC: 0, Transmitter delay is 0 flags I have open tickets with telco and they are not seeing any problems on the ckt. Also, they mention that issue may be hardware related. Are there any troubleshooting test and I can perform on the router, to determine what may be the issue. Cheers
