CRC errors tagged as "total input drops" and input errors seen via "show interface". They should not be categorized as "total input drops". #show int bundle-ether 16 Fri Oct 6 19:53:43.833 UTC Bundle-Ether16 is up, line protocol is up Interface state transitions: 3 Hardware is Aggregated Ethernet interface(s), address is 008a.968a.8908 MTU 8100 bytes, BW 100000000 Kbit (Max: 100000000 Kbit) reliability 199/255, txload 160/255, rxload 228/255 Encapsulation ARPA, Full-duplex, 100000Mb/s loopback not set, Last link flapped 01:40:36 ARP type ARPA, ARP timeout 04:00:00 No. of members in this bundle: 1 HundredGigE0/1/0/16 Full-duplex 100000Mb/s Active Last input 00:00:00, output 00:00:00 Last clearing of "show interface" counters never 30 second input rate 89766739000 bits/sec, 925533 packets/sec 30 second output rate 62931095000 bits/sec, 926249 packets/sec 89614962 packets input, 936305744143 bytes, 1000 total input drops <<<< see here 0 drops for unrecognized upper-level protocol Received 1 broadcast packets, 7305 multicast packets 0 runts, 0 giants, 0 throttles, 0 parity 1000 input errors, 1000 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort <<<<< see here 89650939 packets output, 761464842314 bytes, 0 total output drops Output 2 broadcast packets, 6658 multicast packets 0 output errors, 0 underruns, 0 applique, 0 resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions
Seen on Cisco 8000 devices running LNT software.
No workaround. This is a cosmetic issue that will not cause any traffic impact.
This issue can be seen with giant packets also. show interface bundle-ether 16 Sat Oct 7 03:04:35.376 UTC Bundle-Ether16 is up, line protocol is up Interface state transitions: 3 Hardware is Aggregated Ethernet interface(s), address is 2416.9d2e.f00a MTU 8100 bytes, BW 100000000 Kbit (Max: 100000000 Kbit) reliability 255/255, txload 0/255, rxload 0/255 Encapsulation ARPA, Full-duplex, 100000Mb/s loopback not set, Last link flapped 08:51:28 ARP type ARPA, ARP timeout 04:00:00 No. of members in this bundle: 1 HundredGigE0/0/0/16 Full-duplex 100000Mb/s Active Last input 00:00:00, output 00:00:00 Last clearing of "show interface" counters 00:03:54 30 second input rate 1000 bits/sec, 1 packets/sec 30 second output rate 5470000 bits/sec, 10684 packets/sec 166525 packets input, 709844820 bytes, 38402895 total input drops <<< see here 0 drops for unrecognized upper-level protocol Received 0 broadcast packets, 0 multicast packets 0 runts, 38402895 giants, 0 throttles, 0 parity <<<<<<<< see here 38402895 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort. <<<<<<<< see here 2498897 packets output, 172602104 bytes, 0 total output drops Output 0 broadcast packets, 0 multicast packets 0 output errors, 0 underruns, 0 applique, 0 resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions
