Predefined user roles
network-admin
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.
Expected data check takes place in the following conditions:
•
For features that use the HTTP or HTTPS template, the NQA client checks for the expected
data if the response contains the Content-Length header.
•
For features that use the TCP or UDP template, the NQA client checks for the expected data if
the
data-fill
command is configured.
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.
Examples
# In HTTP template view, set the expected data to
welcome!
.
<Sysname> system-view
[Sysname] nqa template http httptplt
[Sysname-nqatplt-http-httptplt] expect data welcome!
expect ip
Use
expect ip
to specify the expected IPv4 address.
Use
undo expect ip
