Numbers are used to set sizes, rated, addresses, port numbers, priorities, and other such numeric values. They can be entered as a series of digits (without commas or spaces), in a dotted decimal format (such as IP addresses), or separated by colons (such as MAC addresses). Most numeric values use base 10 numbers, while some use hexadecimal values.
Most GUI and CLI fields prevent invalid numbers from being entered. The CLI help text includes information about the range of values allowed for applicable settings.
