Product Description
34
For example, assume that you are connecting a trunk between
two AT-8024 switches. On the first AT-8024 switch you had
chosen ports 12, 13, 14, 15 for the trunk. On the second AT-
8024 switch you had chosen ports 21, 22, 23, and 24. To
maintain the order of the port connections, you would
connect port 12 on the first AT-8024 switch to port 21 on the
second AT-8324, port 13 to port 22, and so on.
G
The ports of a port trunk must be of the same medium type. For
example, they can be all twisted pair ports or all fiber optic ports.
G
For an AT-8024GB Switch, you can create a port trunk of the GBIC
modules installed in the Port A and Port B slots, provided that the
GBIC modules are of the same medium type.
G
The ports on the end node must also be configured as a port
trunk.
Caution
Do not connect the cables of a port trunk to the switch until after
you have created the port trunk using the switch’s management
software. Connecting the cables before the port trunk has been con-
figured will create a data loop in your network topology, and that
could adversely affect network performance.
Example of a Port Trunk
Figure 17 shows an example of a port trunk between an AT-8024 and a
network server. The server is connected to the switch with four data
links. The links are connected to ports 1 through 4 on the switch.
