Command Line Interface
Commands that are entered from the CLI can apply to the entire system or to a specific module, port, or
VLAN. Modules (module slots), ports, and VLANs are numbered starting with 1.
To reference a specific port on a specific module, the command syntax is mod_num/port_num. For
example, 3/1 denotes module 3, port 1. In some commands, such as set trunk, set cam, and set VLAN
commands, you can enter lists of ports and VLANs. Designate ports by entering the module and port
number. Separate the module and port number pairs with commas. To specify a range of ports, use a dash
(-) between the module number and port number pairs. Dashes take precedence over commas.
The following examples show several ways to designate ports:
Example 1:
2/1,2/3 denotes module 2, port 1 and module 2, port 3
Example 2: 2/1-12 denotes module 2, ports 1 through 12
Example 3: 2/1-2/12 is the same as Example 2
A single number designates each VLAN. You specify lists of VLANs in the same way that you do for
ports. Separate individual VLANs with commas (,). Separate ranges with dashes (-). The following
example specifies VLAN numbers 1 through 10:
1-10,1000
Some commands require a MAC address, IP address, or IP alias, which must be designated in a standard
format. The MAC address format must be six hyphen-separated hexadecimal numbers, as shown in the
following example:
00-00-0c-24-d2-fe
The IP address format is 32 bits, written as four octets, which are separated by periods (dotted decimal
format). The address includes a network section, an optional subnet section, and a host section, as shown
in the following example:
126.2.54.1
If the IP alias table is configured, you can use IP aliases in place of the dotted decimal IP address. This
option is available for most commands that use an IP address, except commands that define the IP
address or IP alias. For more information about the set interface and set IP alias commands, see the
command reference for your switch.
Command Line Interface Local Access

Step 1 At the Console> prompt, press Return (or Enter).
Step 2 At the Enter Password: prompt, enter the system password. The Console> prompt indicates that you have
