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.
Thanks

Hello Mohammed,
you should use autonegotiation on both sides and all member links have to be configured on the same way both sides.
Hope to help

My guess is you have the wrong cable between them and auto mdix is correcting the pins. Auto mdix only works when set to auto/auto, when you try to hardcode the ports to a speed it will bring the link down .
