Below are the guidelines to follow when planning a port trunk:
The switch can support up to four port trunks at a time.
G
The duplex mode, speed, and flow control settings must be the
G
same for all of the ports in a trunk.
When cabling a trunk, the order of the connections should be
G
maintained on both nodes. The lowest numbered port in a trunk
on the switch should be connected to the lowest numbered port
of the trunk on the other device, the next lowest numbered port
on the switch should be connected to the next lowest numbered
port on the other device, and so on.
For example, assume that you are connecting a trunk between
two AT-9410GB switches. On the first AT-9410GB switch you
had chosen ports 2, 3, 4, and 5 for the trunk. On the second AT-
9410GB switch you had chosen ports 1, 2, 3, and 4. To maintain
the order of the port connections, you would connect port 2
on the first AT-9410GB switch to port 1 on the second AT-
9410GB, port 3 to port 2, and so on.
The ports of a port trunk must be of the same type. For example,
G
they can be all twisted pair ports or all GBIC ports.
You can create a port trunk of the GBIC modules installed in the
G
GBIC1 and GBIC2 slots, provided that the GBIC modules are of the
same type.
The ports on the end node must also be configured as a port
G
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.
