Displaying IP Configuration Information and Statistics

The following sections describe IP display options for Layer 3 Switches and Layer 2 Switches.
• To display IP information on a Layer 3 Switch, see "Displaying IP Information – Layer 3 Switches" on page 15-
83.
• To display IP information on a Layer 2 Switch, see "Displaying IP Information – Layer 2 Switches" on page 15-
104.

Changing the Network Mask Display to Prefix Format

By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can
change the displays to prefix format (example: /18) on a Layer 3 Switch or Layer 2 Switch using the following CLI
method.
NOTE: This option does not affect how information is displayed in the Web management interface.
USING THE CLI
To enable CIDR format for displaying network masks, entering the following command at the global CONFIG level
of the CLI:
BigIron(config)# ip show-subnet-length
Syntax: [no] ip show-subnet-length
USING THE WEB MANAGEMENT INTERFACE
You cannot configure this option using the Web management interface.
