Step Command

Remarks

289.

Specify the HTTP type and
enter its view.

type http

N/A

290.

Configure the IP address of
the HTTP server as the

destination address of HTTP

request packets.

By default, no destination IP
address is configured.

destination ip ip-address

Optional.
By default, no source IP address is

specified.

291.

Configure the source IP
address of request packets.

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.

source ip ip-address

Optional.
By default, the operation type for

the HTTP is get, which means
obtaining data from the HTTP

server.

292.

Configure the operation type. operation { get | post }

293.

Specify the destination
website URL.

url url N/A

Optional.

294.

Specify the HTTP version.

http-version v1.0

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 "Configuring the NQA server."
