3.
Specify the UDP echo type
and enter its view.
type udp-echo N/A
4.
Specify the destination IP
address of UDP packets.
destination ip ip-address
By default, no destination IP address
is specified.
The destination IP address must be
the same as the IP address of the
listening service configured on the
NQA server.
5.
Specify the destination port of
UDP packets.
destination port port-number
By default, no destination port
number is specified.
The destination port number must be
the same as that of the listening
service on the NQA server.
6.
(Optional.) Specify the
payload size for each UDP
packet.
data-size size
The default setting is 100 bytes.
7.
(Optional.) Specify the
payload fill string for UDP
packets.

Configuring the voice operation
CAUTION:
To ensure successful voice operations and avoid affecting existing services, do not perform the operations
on well-known ports from 1 to 1023.
The voice operation measures VoIP network performance.
The voice operation works as follows:
1.
The NQA client sends voice packets of G.711 A-law, G.711 μ-law or G.729 A-law codec type at
a specific interval to the destination device (NQA server).
2.
The destination device takes a time stamp to each voice packet it receives and sends it back to the
source.
3.
Upon receiving the packet, the source device calculates the jitter and one-way delay based on the
time stamp.
