Step 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 request 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.
Specify the destination
website URL.
url url N/A
8.
Specify the HTTP version.
http-version v1.0
Optional.
By default, HTTP 1.0 is used.
Configuring a UDP jitter operation
CAUTION:
Do not perform the UDP jitter operation to well-known ports from 1 to 1023. Otherwise, the UDP jitter
operation might fail or the service on the well-known port becomes unavailable.
Jitter means inter-packet delay variance. A UDP jitter operation measures unidirectional and
bidirectional jitters so that you can verify whether the network can carry jitter-sensitive services such as
real-time voice and video services.
The UDP jitter operation works as follows:
1.
The NQA client sends UDP packets to the destination port at a regular interval.
2.
The destination device takes a time stamp to each packet that it receives, and then sends the
packet back to the NQA client.
3.
Upon receiving the responses, the NQA client calculates the jitter according to the time stamps.
The UDP jitter operation requires both the NQA server and the NQA client. Before you perform the UDP
jitter operation, configure the UDP listening service on the NQA server. For more information about UDP
listening service configuration, see "
