it a name (TG1 in this example), then click the option to select port members and select
the port member numbers (4/1 and 4/2 in this example). See Figure 7-17.

Tip: Port channel numbers and trunk group numbers are locally significant only. In
other words, when creating aggregations, the port channel number on the upstream
switch and the trunk number on the gateway module can be different on each side of
the link. So for example, the Ethernet gateway module can use Trunk group 1 and the
upstream switch can use aggregation channel-group 5. This is how we demonstrate
aggregation in this example.
