Modifying Trunks

Modifying Trunks
You can modify a trunk in two ways:
■
You can modify a trunk’s characteristics (for example, the operating
mode or the TCMP state).
■
You can add or remove a port from the trunk.
Important
Considerations
■
You must 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 one you that you are modifying.
■
To avoid configuration errors, do not modify 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 Switch (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 Switch to implement the
change.
■
You can modify one or several trunks using a single
modify
command.
Removing Trunks
You can remove one, several, or all trunks using a single
remove
command. This capability saves you from having to reboot the Switch
after each trunk remove.
Important
Consideration
■
If you remove a Gigabit Ethernet module that has trunks defined,
NVRAM is not cleaned up, but the trunk ports are available for use by
a replacement module of the same type.
