Displaying IP configuration information and statistics
The following sections describe IP display options for Layer 3 switches and Layer 2 switches.
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.
To enable CIDR format for displaying network masks, entering the following command at the global CONFIG level of the CLI.
device(config)# ip show-subnet-length
