ip-address: Specifies the IP address for the UDP listening service.
port-number: Specifies the port number for the UDP listening service, in the range of 1 to 65535.
vpn-instance vpn-instance-name: Specifies a VPN instance by its name, a case-sensitive string of 1 to 31
characters. If you do not specify this option, the NQA server listens on a public IP address.

to 255, and the default value is 0.
Usage guidelines
Use this command on the NQA server only for the UDP jitter, UDP echo, and voice operations.
When you configure the IP address and port number for a UDP listening service on the NQA server,
follow these restrictions and guidelines:
• The IP address and port number must be unique on the NQA server and match the configuration on
the NQA client.
• The IP address must be the address of an interface on the NQA server.
• To ensure successful NQA operations and avoid affecting existing services, do not configure the
UDP listening service on well-known ports from 1 to 1023.
Examples
# Configure a UDP listening service to enable the NQA server to listen and respond on the IP address
169.254.10.2 and port 9000.
