On the BlackDiamond, the port number is a combination of the slot number and the
port number. The nomenclature for the port number is as follows:
slot:port
For example, if a G4X I/O module (having a total of four ports) is installed in slot 2 of
the BlackDiamond chassis, the following ports are valid:
•
2:1
•
2:2
•
2:3
•
2:4
You can also use wildcard combinations (*) to specify multiple BlackDiamond slot and
port combinations. The following wildcard combinations are allowed:
•
slot:*
— Specifies all ports on a particular I/O module.
•
slot: x -slot: y
— Specifies a contiguous series of ports on a particular I/O
module.
•
slot a : x - slot b : y
— Specifies a contiguous series of ports that begin on one I/O
module and end on another I/O module.

By default, all ports are enabled. To enable or disable one or more ports, use the
following command:
[enable | disable] port <slot:portlist>
For example, to disable slot 7, ports 3, 5, and 12 through 15 on the BlackDiamond, enter
the following:
disable port 7:3,7:5,7:12-7:15
Even though a port is disabled, the link remains enabled for diagnostic purposes.
