This is a particularily weird one :-) - what will your co-worker do 
if vlan 1200 gets added to po1318?  Renumber the port-channel?


We usually decide on a case-by-case basis how to number the port-channels,
and then it's usually something like:

 - from distribution router (6500) to distribution switches (whatever)
     port-channel 1, 2, 3, 4... to dist-switch 1, 2, 3, 4...

 - from distribution router to core router
     port-channel 100, 101, 102, ...

That's about what we use.  Tacking port-channel numbers to vlans on the
channel will give you headaches some day - vlan distribution tends to
change all the time.
