Table 53: Pattern Criteria Values
Value Description
Pattern A pattern can be a regular expression string pattern in ASCII characters, or a binary
pattern in hexadecimal notation. For more information on using regular expressions
to match pattern data, see
Regular Expression Matching, page 803 .
If the pattern is binary, specify the binary pattern in hexadecimal notation. For
example, to specify the binary pattern
1111 1100 0010 1101
, enter
FC2D
.
Offset An offset value is the byte count from the start of the IP header, from which a
search or compare operation is performed. An offset value is always required when
the creating pattern strings, even if the desired value is zero (0).
For example, if an offset of 12 is specified, Alteon starts examining the hexadecimal
representation of a binary string from the 13th byte. In the IP packet, the 13th byte
starts at the source IP address portion of the IP payload.
