Command Remarks
5. Configure the source IP
address of request packets.
source ip ip-address
Optional.
By default, no source IP address is
specified.
The source IP address must be the IP
address of a local interface. The local
interface must be up; otherwise, no
probe packets can be sent out.
6. Configure the operation type.
operation { get | post }
Optional.
By default, the operation type for the
HTTP is get, which means obtaining data
from the HTTP server.
7. Configure the website that an
HTTP test visits.
url url N/A
8. Configure the HTTP version
used in HTTP tests.
http-version v1.0
Optional.
By default, HTTP 1.0 is used.
9. Configure optional
parameters.
See "Configuring optional
parameters for an NQA test
group"
Optional.
NOTE:
The TCP port must be port 80 on the HTTP server for NQA HTTP tests.
Configuring UDP jitter tests
NOTE:
Do not perform NQA UDP jitter tests on known ports, ports from 1 to 1023. Otherwise, UDP jitter tests
might fail or the corresponding services of this port might be unavailable.
Real-time services such as voice and video have high requirements on delay jitters. UDP jitter tests of an
NQA test group obtain uni/bi-directional delay jitters. The test results help you verify whether a network
can carry real-time services.
A UDP jitter test takes the following procedure:
1. The source sends packets at regular intervals to the destination port.
2. The destination affixes a time stamp to each packet that it receives, and then sends it back to the
source.
3. Upon receiving the response, the source calculates the delay jitter, which reflects network
performance. Delay refers to the amount of time it takes a packet to be transmitted from source to
destination or from destination to source. Delay jitter is the delay variation over time.
Configuration prerequisites
UDP jitter tests require cooperation between the NQA server and the NQA client. Before you start UDP
jitter tests, configure UDP listening services on the NQA server. For more information about UDP listening
service configuration, see "Configuring the NQA server."
