The ports on the AT-8224XL Switch are divided into five groups, as
illustrated in Figure 29.
Figure 29 Port Groupings on the AT-8224XL Switch
The ports on the AT-8288XL Switch are divided into four groups, as
illustrated in Figure 29.
Figure 30 Port Groupings on an AT-8288XL Switch (Model AT-
8288XL/SC)
The ports of a port trunk must be members of the same group. You
cannot create a port trunk using ports from different groups. For
example, you could use ports 4 and 5 on an AT-8224XL Switch as one
port trunk, since the ports are members of the same group. However,
ports 7, 8, 9, and 10 cannot be combined to form a port trunk on an AT-
8224XL Switch because they belong to different groups.
Guideline 3: Using Consecutive Ports
The ports of a trunk must be consecutive. For example, you could use
ports 4, 5, 6, and 7 as one port trunk because the ports are consecutive.
Guideline 4: Creating Only One Trunk Per Group
Each group of ports on a Fast Ethernet switch can support only one port
trunk. For example, the AT-8224XL Ethernet Switch has three port
groups, assuming no expansion modules. Consequently, this switch can
support three port trunks, one port trunk for each port group. The
addition of an expansion module in the bottom expansion slot would
enable the switch to support one additional port trunk.
