Note
A port that already belongs to a static port trunk must be removed
from its current assignment before it can be added to another port
trunk. To remove a port from a trunk, see “DELETE SWITCH
TRUNK” on page 148.
Example
The following command adds port 1.5 to a port trunk called load22:
add switch trunk=load22 port=1.5
