MASK Command

The MASK command can limit the display of flows.

This command has the following syntax:

MASK value
value

Indicates a string that is used to select which flows to display. The string can contain one or more wildcard characters. The character '*' (asterisk) can be used to match any number of characters, including no characters. The character '?' will only match a single non-blank character. If a mask value is not entered, a mask of '*' is used.

The following table gives some examples of mask values and flow names that they would and would not match.
