Well, we had our ISP clear the stats, and their end is showing no errors... Here is the output before and after, although the stats before are like 35 weeks old. The second stats are about three hours old. ba01.b001200-2.lax01#sh int FastEthernet21 FastEthernet21 is up, line protocol is up Hardware is epif_port, address is 0005.5e43.eb1b (bia 0005.5e43.eb1b) Description: CUST-W FE LZ-MO MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 187/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec) Full-duplex, 100Mb/s, 100BaseTX ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 35w0d Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 28864000 bits/sec, 6461 packets/sec 5 minute output rate 73561000 bits/sec, 7564 packets/sec 771797665 packets input, 3456898980 bytes, 0 no buffer Received 10505 broadcasts, 86892 runts, 15 giants, 0 throttles 188392 input errors, 90405 CRC, 11080 frame, 0 overrun, 0 ignored, 0 abort 0 watchdog, 30038839 multicast 0 input packets with dribble condition detected 2127564566 packets output, 1282358462 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out ba01.b001200-2.lax01#sh int FastEthernet21 FastEthernet21 is up, line protocol is up Hardware is epif_port, address is 0005.5e43.eb1b (bia 0005.5e43.eb1b) Description: CUST-W FE LZ-MO MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 192/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec) Full-duplex, 100Mb/s, 100BaseTX ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 02:44:02 Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 1/75, 0 drops 5 minute input rate 21260000 bits/sec, 5911 packets/sec 5 minute output rate 75635000 bits/sec, 7375 packets/sec 57291936 packets input, 981288818 bytes, 0 no buffer Received 9 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 watchdog, 0 multicast 0 input packets with dribble condition detected 72313803 packets output, 2238000602 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out
