Chapter 6: Static Port Trunks
84 Section I: Basic Operations
Creating a Static Port Trunk
Caution
Do not connect the cables of a port trunk to the ports on the switch
until after you have configured the ports on both the switch and the
remote device. Connecting the cables prior to configuring the trunk
can create a loop in your network topology. This can cause a
broadcast storm and poor network performance.
Note
Prior to creating a static 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 home page, select Configuration.
2. From the Configuration menu, select the Layer 1 option.
3. Select the Port Trunking tab.
