The ports on the AT-8316/MT and AT-8316/VF switches are divided
into four groups, as shown in Figure 2-5.
Figure 2-5 Port Groups on an AT-8316F/MT or AT-8316/VF Switch
The ports on the AT-8316/SC switch also are divided into four
groups, as shown in Figure 2-6.
Figure 2-6 Port Groups on an AT-8316F/SC Switch
As mentioned previously, the ports for a port trunk must be
members of the same group. A port trunk cannot consist of ports
from different groups. For example, you could use ports 4 and 5 on
an AT-8324 switch as one port trunk, and this would be valid since
the ports are members of the same group. However, ports 7, 8, 9, and
10 cannot be combined to form one port trunk on an AT-8324 switch
because these ports belong to different groups.
Guideline 3:
Creating Only
One Trunk Per
Group
Each group of ports on an Ethernet switch can support only one port
trunk. For example, the AT-8324 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 two expansion modules would enable the switch to
support two additional port trunks, one for each module.
Guideline 4:
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, and this would be valid because
the ports are consecutive. However, an invalid selection of ports for a
trunk would be 1, 3, 5, and 7 since these ports are not consecutive.
