Creating a Port Trunk
This section contains the procedure for creating a port trunk on the
switch. Be sure to review the guidelines in ”Port Trunking Overview” on
page 142 before performing the procedure.
Caution
Do not connect the cables to the trunk ports on the switches until
after you have configured the trunk with the AT-S63 management
software. Connecting the cables before configuring the software
creates a loop in your network topology. Data loops can result in
broadcast storms and poor network performance.
Note
Before you create a port trunk, examine the speed, duplex mode,
and flow control settings of the lowest numbered port that will be a
part of the trunk. Check to be sure that the settings are correct for
the end node to which the trunk will be connected. When you create
the trunk, the AT-S63 management software copies the settings of
the lowest numbered port in the trunk to the other ports so that all
the settings are the same.
You should also check to be sure that the ports are untagged
members of the same VLAN. You cannot create a trunk of ports that
are untagged members of different VLANs.
To create a port trunk, perform the following procedure:
1. From the Main Menu, type 1 to select Port Configuration.
The Port Configuration menu is shown in Figure 26 on page 106.
2. From the Port Configuration menu, type 4 to select Port Trunking.
