Parameters
expression: Specifies the expected data, a case-sensitive string of 1 to 200 characters.
offset number: Specifies the offset in bytes after which the first match operation starts. The value
range for the number argument is 0 to 1000, and the default value is 0. If you do not specify an offset,
the match operation starts from the beginning byte of the payload.
Usage guidelines
Upon receiving a response packet, the NQA client examines the target payload for the expected
data.
• If a match is found, the NQA client verifies the NQA destination device as legal.
• If no match is found, the NQA client looks up the entire payload for a match. If no match is found
again, the NQA destination device is verified as illegal. The NQA client does not perform the
second round if no offset is specified. It verifies the NQA destination as illegal directly if no
match is found for the first round.
