Hi Jason, I would recommend clearing the counters on the interface that having the issue?
Clear counter gi0/2.. and monitor for a few minutes.... It looks like the GBIC may be going bad, try replacing it... I would also recommend having the cable dogs do a Db loss test on the fiber, just to see if the tips are good.. Best of luck... ________________________________ From: Jason LeBlanc <[email protected]> To: [email protected] Sent: Thu, December 3, 2009 6:23:18 PM Subject: [OSL | CCIE_RS] 7200 <-> 6506 Fiber Hello, I am having trouble with input errors and overrun errors between a Cisco 7206VXR (NPE-G1) and a cisco WS-C6506: GigabitEthernet0/2 is up, line protocol is up Hardware is BCM1250 Internal MAC, address is 000c.8651.a41a (bia 000c.8651.a41a) description /* Uplink to 6509 Gig1/14 */ Internet address is 10.1.1.2/30 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 12/255, rxload 24/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 1000Mb/s, link type is force-up, media type is SX output flow-control is unsupported, input flow-control is unsupported 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 04:33:41 Input queue: 1/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 94404000 bits/sec, 18329 packets/sec 5 minute output rate 47074000 bits/sec, 24034 packets/sec 249326344 packets input, 169932937197 bytes, 0 no buffer Received 4796 broadcasts, 0 runts, 0 giants, 0 throttles 17233 input errors, 0 CRC, 0 frame, 17233 overrun, 0 ignored <---- Errors 0 watchdog, 4796 multicast, 0 pause input 0 input packets with dribble condition detected 304531507 packets output, 67231420161 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 pause output 0 output buffer failures, 0 output buffers swapped out GigabitEthernet1/14 is up, line protocol is up (connected) Hardware is C6k 1000Mb 802.3, address is 0006.2a22.6400 (bia 0006.2a22.6400) description /* Uplink to 7200 Gig0/2 */ Internet address is 10.1.1.1/30 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 23/255, rxload 12/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 1000Mb/s, media type is SX input flow-control is off, output flow-control is off Clock mode is auto 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 19w3d Input queue: 0/75/0/3494 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 48767000 bits/sec, 23812 packets/sec 5 minute output rate 92734000 bits/sec, 17980 packets/sec L2 Switched: ucast: 60531768 pkt, 5655063889 bytes - mcast: 2130916 pkt, 682139248 bytes L3 in Switched: ucast: 126175090872 pkt, 27258494314476 bytes - mcast: 0 pkt, 0 bytes mcast L3 out Switched: ucast: 89343262158 pkt, 48967491000849 bytes mcast: 0 pkt, 0 bytes 126210460243 packets input, 27258566888042 bytes, 0 no buffer Received 2326763 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 input packets with dribble condition detected 89334634869 packets output, 48958989988931 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 interface GigabitEthernet0/2 description /* Uplink to 6509 Gig1/14 */ ip address 10.1.1.2 255.255.255.252 no ip redirects ip route-cache flow duplex full speed 1000 media-type gbic no negotiation auto end interface GigabitEthernet1/14 description /* Uplink to 7200 Gig0/2 */ ip address 10.1.1.1 255.255.255.252 speed nonegotiate end Is there a recommended configuration for fiber connects between these two device types?
