Port Numbering
On a Summit 300-48 switch, 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
You can use wildcard combinations (*) to specify multiple slot and port combinations. The following
wildcard combinations are allowed:
•
— Specifies all ports on a particular I/O module.
slot:*
•
slot:x-slot:y
•
slota:x-slotb:y
on another I/O module.
Enabling and Disabling Switch Ports
By default, all ports are enabled. To enable or disable one or more ports, use the following command:
[enable | disable] ports <portlist>
For example, to disable slot 1, ports 3, 5, and 12 through 15 on a Summit 300-48 switch, use the
following command:
disable ports 1:3,1:5,1:12-1:15
