I'm trying to configure a port-channel between two 6807xl chassis, I have got a 40G module and 4x10G in each of them, I would like creating a port-channel between the two devices using that five ports (40+4x10=80G), I create the port-channel but when I try to configure the ports to join the PoCh I get an error. If I configure until 8x10G there is no problem, but if I configure first the 40G port and then the rest of the ports, I only can join 3 more of them and I get the next error:
Router(config-if)#channel-group 250 mode on
Command rejected (Port-channel250, Fo1/1): Channel group limit reached
I guest there is a limitation using 40G and 10G ports, could someone confirm that???
