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. The fixed-configuration switches have two logical modules. The Catalyst 4912G, the Catalyst 2948G, and the Catalyst 2980G switches have 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. With many commands, you can enter lists of ports. To specify a range of ports, use a comma-separated list (do not insert spaces) to specify individual ports or a hyphen (-) between the port numbers to specify a range of ports. Table 2-4 shows examples of how to designate ports and port ranges. 78-15486-01 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 2-7
