[c-nsp] 6500/Sup2/6516A - Strange GE problems...

[Deepak Jain]

This seems a bit strange, but its consistent between two chassises in 
identical configurations so I'm wondering if its a feature or a bug. OS 
is identical: System image file (native) is 
"sup-bootflash:c6sup22-pk2sv-mz.121-26.E.bin"

Basically, when connecting any GE device to either of these routers -- 
on the Sup2 or the 6516A, we have to do a "shut, no shut" on a port to 
get link.

A typical show interface shows up/down:
GigabitEthernet2/1 is up, line protocol is down (notconnect)
   Hardware is C6k 1000Mb 802.3, address is
   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, 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 never, output 00:26:47, output hang never
   Last clearing of "show interface" counters never
   Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
   Queueing strategy: fifo
   Output queue: 0/40 (size/max)
   5 minute input rate 0 bits/sec, 0 packets/sec
   5 minute output rate 0 bits/sec, 0 packets/sec
   L2 Switched: ucast: 0 pkt, 0 bytes - mcast: 0 pkt, 0 bytes
   L3 in Switched: ucast: 0 pkt, 0 bytes - mcast: 0 pkt, 0 bytes mcast
   L3 out Switched: ucast: 0 pkt, 0 bytes
      0 packets input, 0 bytes, 0 no buffer
      Received 0 broadcasts (0 IP multicast)
      0 runts, 0 giants, 0 throttles
      0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 watchdog, 0 multicast, 0 pause input
     0 input packets with dribble condition detected
     0 packets output, 0 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

Yet, a shut/no shut with no physical changes will bring the link right 
up. Remove the cable and re-insert, and this shut/no shut needs to be 
repeated on both sides (for a connection between these two 6500s). If a 
6500 is connected to known working 3550 or 3548, the 6500s need the 
shut/no shut but the 3xxx ones don't.  The GBICs on the 3xxx switches 
will recognize each other immediately with no operator intervention.

We've tried swapping GBICs, re-inserting cards, new cables, new 
connectors, cleaning the connectors, using different ports & different 
cable lengths.

Since the problem is essentially identical between the same hardware 
running the same IOS versions (native) I'm wondering if the line cards 
need their versions upgraded or we need to be running these on a 
different IOS version or if maybe we have a bad batch of GBICs or hardware.

Suggestions, comments, ideas would be appreciated. Cisco-nsp has been 
quicker to the solution than TAC in almost every case.

Thanks,

DJ
