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."
