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 NQA client looks up the received packet's
payload for the expected data. The value range for the
number
argument is 0 to 1000, and the
default value is 0.
Usage guidelines
Upon receiving a response packet, the NQA client looks up the packet's 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 verifies the NQA destination device as illegal.
The first five bytes of the UDP packet payload identify the probe packet type. The start byte of the
offset is the sixth byte of the UDP payload.
Expected data check takes place in the following conditions:
