Displaying IP configuration information and statistics
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.
To enable CIDR format for displaying network masks, entering the following command at the global
CONFIG level of the CLI.
Brocade(config)# ip show-subnet-length
Syntax: [no] ip show-subnet-length
