Configuring Udp Jitter Tests - HP 5820X Switch Configuration Manual

To do...
4. Configure the IP address of
the HTTP server as the
destination address of HTTP
request packets.
5. Configure the source IP
address of request packets.
6. Configure the operation type.
7. Configure the website that an
HTTP test visits.
8. Configure the HTTP version
used in HTTP tests.
9. Configure optional
parameters.
NOTE:
The TCP port must be port 80 on the HTTP server for NQA HTTP tests.

Configuring UDP jitter tests

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:
The source sends packets at regular intervals to the destination port.
1.
The destination affixes a time stamp to each packet that it receives, and then sends it back to the
2.
source.
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.
Use the command...
destination ip ip-address
source ip ip-address
operation { get | post }
url url
http-version v1.0

parameters for an NQA test

Remarks
Required.
By default, no destination IP
address is configured.
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.
Optional.
By default, the operation type for
the HTTP is get, which means
obtaining data from the HTTP
server.
Required.
Optional.
By default, HTTP 1.0 is used.
