Hi,
I been practicing with the configuration of layer 3 etherchannel configuration and i am facing a problem here. I have two 3560 switches and i want a layr 3 ether channel configuration setup between the first 2 ports of bothe the switches. I assign IPs to the Port-channel 1 of both the switches "10.1.1.1 /24 and 10.1.1.2 /24" but i am unable to get a successful ping. what am i doing wrong. below are the configs for bothe of my switches.

You need to have channel-group command on both sides (desirable must be used on one or both). channel-protocol command is not neccessary.

like Sergey said, you need it on both sides....your half way there...
put the command "channel-group 1 mode desirable" or "channel-group 1 mode on" on both ends you will be good...
