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.
tos: Specifies the ToS value in the IP packet header of NQA probe packets. The value range is 0 to 255
and the default value is 0.
vpn-instance-name: Specifies the name of the MPLS L3VPN instance, a case-sensitive string of 1 to 31
characters. If you do not specify this argument, the NQA server listens on a public IP address.
Use this command on the NQA server for only the UDP jitter, UDP echo, and voice operations.
You can use this command to specify the ToS value in the IP packet header of NQA probe packets.
The IP address and port number must be consistent with those configured on the NQA client and must be
different from the IP address and port number for an existing UDP listening service.
The IP address must be that of an interface on the NQA server. Otherwise, the configuration becomes
Do not perform the UDP listening service on well-known ports from 1 to 1023. Otherwise, the NQA
operation might fail, or the service on the port might become unavailable.
