I created a port channel on a 3550-12G switch, when I tried to configure the ip address it gave a error message saying that "a ip address can not be configured on a lay2 box. This switch 3550-12G is setup as a layer3 switch I'm not sure why it's not allowing me to configure an ip address on the port channel interface.
Thanks,

When you say the 3550 is setup as a layer 3 switch, you mean that the 'ip routing' command has been enabled, right ?

You need to enter the no switchport command. This turns the port / portchannel into layer 3.
The same command will need to be entered into each port that you are going to have in that channel-group.
eg:
3550-1#conf t
3550-1(config)#interface po1
3550-1(config-if)# no switchport
3550-1(config-if)# ip address 10.1.1.1 255.255.255.0
3550-1(config-if)#exit
3550-1(config)#interface fa0/1
3550-1(config-if)#no switchport
3550-1(config-if)#channel-group 1 mode on
Hope this helps

or enable routing on the whole thing
3550# conf t
3550(config)# ip routing
