port channel numbering

liven

I have noticed that in the cisco BCMSN lab book and through my own expierementation that the port channel group numbers don't have to match on each switch.


For example:


switch A has ports fast eth 0/1 and 0/2

connected

to

swtich B ports fast eth 0/1 and 0/2



A trunk has been created.

And I was able to get ether channel working by using:


swtich A:

channel-group 1 mode desirable


and


switch B:

channel-group 5 mode desirable

And the ether channel is established.... So am I correct in assuming that the group numbers are only for local use and don't have to match on both devices?

The number you use is locally significant and can be different on both ends of the channel group.
