R0106-HP MSR Router Series Network Management and Monitoring Command Reference(V7)

81
tos tos: Specifies the ToS value in the IP header for reply packets. The value range for the tos argument
is 0 to 255, and the default value is 0.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN 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.
Usage guidelines
Use this command on the NQA server for only 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 that of an interface on the NQA server. Otherwise, the configuration
becomes invalid.
• 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.
<Sysname> system-view
[Sysname] nqa server udp-echo 169.254.10.2 9000
