RE: Oldschool CatOS GEC question...

The admin group allows you to create port channels across blades in the
Catalyst. Originally port channel ports had to be on the same blade, then
they came up with the admin group concept to tie ports on different blades
to the same port channel.

We ran into this creating port channels in our data centre. To get the
cross blade channel to come up we had to manually configure the ports in
the same admin group.

IOS does this automatically in the background.
