Specifying Modules, Ports, and VLANs
Modules, ports, and VLANs are numbered sequentially, beginning with 1. The supervisor engine module
is module 1, residing in slot 1.
To designate a specific module, use the module number. In most systems, the module number and the
slot number are the same.
On the fixed-configuration switches, there are two logical modules. On the Catalyst 4912G, the
Catalyst 2948G, and the Catalyst 2980G switches, there are two modules but only one slot. When you
enter configuration commands on these switches, you must refer to the module number, not the slot
number. For example, all of the user-configurable ports on these switches are logically on module 2.
On modules that have user-configurable ports, the left-most port is always port 1. To designate a specific
port on a specific module, the command syntax is mod_num/port_num. For example, 3/1 specifies
module 3, port 1. On the Catalyst 4912G, the Catalyst 2948G, and the Catalyst 2980G switches, the
left-most switch port is numbered 2/1 instead of 1/1 because logically the ports are located on module 2.
