[c-nsp] 3550 Frequent Port Hardware failure

[Kevin.X.White at corusgroup.com]

Hi,

 We are seeing frequent (3 failed switches out of 7 in 2 yrs!) failures on
our 3550-FXs

All are port failures, symptoms may be:

ports flap with nothing but a cap on the port,
ports fail loopback test on powerup,
ethernet controllers fail powerup etc.

Our hardware support partners have run 'test firmware' & confirmed the H/W
is indeed faulty!

However, all of the remaining functional ports continue to route/switch
properly,
SNMP & CLI work fine with nothing in the error log (execept
flap/errdissable records)

Does anyone see this level of failure in 3550 H/W or in any other Cisco
kit, (btw the mtbf for 3550 H/W is around 22 yrs!)
