ADD SWITCH TRUNK
Syntax
add switch trunk=name port=ports
Parameters
trunk Specifies the name of the trunk to be modified. (You
can enter any alphanumeric character for the name
and this command will still work. This is extremely
useful if you forgot the name you assigned the trunk.)
port Specifies the ports to be added to the existing port
trunk. The ports can be specified individually (e.g., 1,2,)
or as a range (e.g.,1- 2). A port trunk cannot have more
than four ports.
Description
You can use this command to add one or more ports to an existing port
trunk. For example, if the switch has a port trunk of Port 5 and 9 and you
want to Port 7, you could use this command to add the port to the trunk.
Note
To initially create a port trunk, see the CREATE SWITCH TRUNK
command.
Example
The following command adds Port 5 to an existing port trunk:
add switch trunk=a port=5
