Hi Weidong,
If you look at this link below, you will see a paragraph a little further
down:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12119ea1/3550cr/cli1.htm#1860162
"Any configuration or attribute changes you make to the port-channel
interface are propagated to all interfaces within the same channel group as
the port channel (for example, configuration changes are also propagated to
the physical interfaces that are not part of the port channel, but are part
of the channel group)."
So, the number is locally significant, to group together interfaces that on
the same switch.

Subject: channel group number's significancy domain
> Hi,

> If I config layer 2 channel-groups between 2 switches, using different
channel group numbers between them (sw1 use 10 and sw2 use 11, like below),
will the channel work?

> The question can be express as: is the channel group number only
significant on the switch or between switches?
