bridge trunk modify Changes a trunk in either of two ways:
■
Modifies a trunk’s characteristics (for example, a Fast Ethernet
operating mode or the Trunk Control Message Protocol (TCMP) state).
■
Adds or removes a port from the trunk, as long as you maintain at
least one of the original ports in the trunk.

Important Considerations
■
Keep at least one port that you defined in the original trunk. To
completely redefine a trunk configuration, remove the trunk and
define a new one.
■
You cannot modify, add, or remove ports that are part of different
trunks from the trunk that you are modifying.
■
To avoid configuration errors, do not modify Fiber Distributed Data
Interface (FDDI) station mode port pairs when any of the ports in the
pair are members of a trunk.
■
If you have more than one media type on your system (for example,
Fast Ethernet and Gigabit Ethernet), you are prompted for a media
type before you are prompted for the trunk information.
■
Any changes that you make to the trunk’s characteristics take effect
immediately and do not interrupt trunk operations. If you add or
remove a port, however, you must reboot the system to implement
the change.
