I am experiencing a problem with some user ports in two Cat 6506 switches with IOS.
After some time in use, some ports are unable to forward traffic. I have to hardcode the speed and duplex in the switch port to make them work. Some times at 100-full others at 10-half. Does anyone have come across this problem? The cards in the switch are WS-X6748-GE-TX and the IOS is IOS (tm) s72033_rp Software (s72033_rp-JK9SV-M), Version 12.2(18)SXD4, RELEASE SOFTWARE (fc1)
I have looked in the web site for any bug or reference to this problem but I haven't found anything. Much appreciated if someone can point me in the right direction.
