Need help GigE between Luxn<-->Cisco7500
Hello, We have recently turned up a GigE link (~5 miles) between our two facilities. The carrier, Time W, is using Luxn 3202 optical access devices as termination gear on each end of the link. The luxns in turn connect via GigE to two cisco 7507 GEIP (we know about GEIP vs GEIP+). diagram 10 ft 5 mile 10 ft cisco7507----- Lyxn 200===CO=====Luxn 1019 ------cisco7507-1019 ^^^ ^^^ ^^^ multi-mode single-mode multi-mode The Cisco 7507 gigE port at 1019 sees alot of Giant packets and %OSPF-4-ERRRCV errors suggesting that the ethernet frames are getting corrupted. MTU on each cisco is 1500 and the link is forced to 1000. We consistently see packet losses of 10-20% with no load at all. If anyone has any experience with Luxn gear and/or Luxn-cisco interconnection please contact me off list. thanks ak -----------------details-------------------------- interface GigabitEthernet5/0/0 ip address X.X.X.1 255.255.255.252 ip route-cache distributed load-interval 30 no negotiation auto GigabitEthernet5/0/0 is up, line protocol is up Hardware is cyBus GigabitEthernet Interface, address is 0050.73a0.bda0 Internet address is X.X.X.2/30 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex mode, 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 00:00:07, output 00:00:01, output hang never Last clearing of "show interface" counters 1d19h Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 30 second input rate 0 bits/sec, 1 packets/sec 30 second output rate 1000 bits/sec, 1 packets/sec 351887 packets input, 43900564 bytes, 0 no buffer Received 34773 broadcasts, 0 runts, 1028 giants, 0 throttles 0 input errors, 0 CRC, 73419 frame, 0 overrun, 0 ignored 0 watchdog, 19308 multicast, 0 pause input 0 input packets with dribble condition detected 181113587 packets output, 2653176686 bytes, 0 underruns(0/0/0) 0 output errors, 0 collisions, 3 interface resets 0 babbles, 0 late collision, 0 deferred 2 lost carrier, 0 no carrier, 0 pause output 0 output buffer failures, 0 output buffers swapped out
