cat6500 side is fastethernet and set to speed 100 and duplex full
ibm side is gig is set to auto/ auto
Things working fine with the error above
But when i set the ibm side to speed 100 and duplex full or half ports will show down/down
i have total of 4 ports on each side forming etherchannel using desirable mode non-silent on the 6500 and same mode on ibm side but without the non-silent command
Any help greatly appreciated.
