AT-8000 Series Fast Ethernet Switches Installation Guide

# You can create a port trunk of the GBIC modules installed in the
Port A and Port B slots of an AT-8024GB Switch, provided that the
GBIC modules are of the same medium type.
# You can create a port trunk using the two fiber optic ports in an
AT-8026FC Switch.
# 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
configured will create a data loop in your network topology, and
that could adversely affect network performance.
Figure 17 illustrates an example of a port trunk. Two AT-8024 Fast
Ethernet Switches are interconnected with a port trunk consisting of
four data links.
