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 Port Trunking Overview on page 122 before
performing the procedure.
Caution
If you will be 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, which can produce broadcast storms and
poor network performance.
Note the following before performing this procedure:
❑ If you are adding a port and the port will be the lowest numbered
port in the trunk, its parameter settings will overwrite the settings
of the existing ports in the trunk. Consequently, you should check
to see if its settings are appropriate prior to adding it.
❑ If you are adding a port and the port will not be the lowest
numbered port in the trunk, its settings will be changed to match
the settings of the existing ports in the trunk.
❑ If you are adding a port to a trunk, you should check to be sure
that the new port is an untagged member of the same VLAN as
the other trunk ports. A trunk cannot contain ports that are
untagged members of different VLANs.
To modify a port trunk, do the following:
1. From the Home Page, select Configuration.
