with the values in the pattern. If a match occurs, then this portion of the condition is satisfied. The

headers display in decimal or hexadecimal. Note that although you can display the data in different
formats, all formats use a byte boundary. Only byte quantities can be entered or displayed.
Any specific value you create for templates can have "don't care" values. For example, assume
you're only looking for FFFF34 in the first three bytes of the MAC destination address. You could
specify the values in your template as FFFF34XXXXXX, where X indicates you don't care about
the values in the last three offsets. Note that for IPv4 addresses, which uses decimal values, using
X characters as partial sub-addresses will cause the complete sub-address to be treated as
wildcard. For example, 128.12X.2.2 will be treated as 128.XXX.2.2.
The hex or decimal patterns display in black or magenta. Displays in

The bytes are a macro pattern; for example, the logical OR of two different address patterns that
make up a two-way conversation. Note also that many ASCII patterns have no corresponding
display character.
