Modifying a Port Trunk
This procedure adds and removes ports from a port trunk.
Note
You should disconnect the cables from the ports of the trunk on the
switch before modifying it. Adding or removing ports from a trunk
without first disconnecting the cables can create loops in your
network topology, which can cause broadcast storms and poor
network performance.
To add or remove ports from a trunk, perform the following procedure:
1. From the Advanced Config menu, select Trunk Config.
The Trunk Configuration page is shown in Figure 59.
2. Click the status of the port trunk to be modified and change the status
from Enable to Disable.
Note
Allied Telesyn recommends disabling a port trunk before adding or
removing ports.
3. Click Apply.
4. To add or remove a port from a trunk, click the check box for the port in
the corresponding trunk row. A check in a box indicates the port is a
member of the trunk. No check means the port is not a member.A port
trunk can contain up to eight ports.
5. Click Apply.
6. Modify the port trunk on the other switch and reconnect the cables.
