Modifying Trunks 233Modifying Trunks You can modify a trunk in two ways:n You can modify a trunk’s characteristics (for example, the operatingmode or the TCMP state).n You can add or remove a port from the trunk.ImportantConsiderationsn You must keep at least one port that you defined in the original trunk.To completely redefine a trunk configuration, remove the trunk anddefine a new one.n You cannot modify, add, or remove ports that are part of differenttrunks from the one you that you are modifying.n To avoid configuration errors, do not modify FDDI station modeport-pairs when any of the ports in the pair are members of a trunk.n If you have more than one media type on your Switch (for example,Fast Ethernet and Gigabit Ethernet), you are prompted for a mediatype before you are prompted for the trunk information.n Any changes that you make to the trunk’s characteristics take effectimmediately and do not interrupt trunk operations. If you add orremove a port, however, you must reboot the Switch to implement thechange.n You can modify one or several trunks using a single modifycommand.Removing Trunks You can remove one, several, or all trunks using a single removecommand. This capability saves you from having to reboot the Switchafter each trunk remove.ImportantConsiderationn If you remove a Gigabit Ethernet module that has trunks defined,NVRAM is not cleaned up, but the trunk ports are available for use bya replacement module of the same type.
