Modifying a Port Trunk
This section contains the procedure for modifying a port trunk on the
switch. You can change the name of a trunk and the ports that constitute
the trunk. You cannot change the load distribute method. Be sure to
review the guidelines in Chapter 8, “Port Trunking,” in the AT-S63
Management Software Menus Interface User’s Guide before you perform
the procedure:
Caution
If you are adding or removing ports from the trunk, you should
disconnect all data cables from the ports of the trunk on the switch
before performing the procedure: Adding or removing ports from a
port trunk without first disconnecting the cables may result in loops
in your network topology. Loops can produce broadcast storms and
poor network performance.
Note
Before you modify a port trunk, examine the speed, duplex mode,
and flow control settings of the lowest numbered port that are to be
in the trunk. Check to be sure that the settings are correct for the
end node to which the trunk is to be connected. When you modify
a 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 modify a port trunk, perform the following procedure:
1. From the home page, select Configuration.
The System page is displayed with the General tab selected by
