Procedure

1. Run:

   system-view

   The system view is displayed.

2. Run:

   nqa twamp-light

   The TWAMP Light view is displayed.

3. Run:

   responder

   The TWAMP Light Responder is enabled, and the TWAMP Light Responder view is displayed.

4. Run:

   test-session session-id local-ip local-ip-address remote-ip remote-ip-address local-port local-port remote-port remote-port [ vpn-instance vpn-instance-name ] [ description description ]

   A TWAMP Light test session is created.

   • After a test session is configured, its parameters cannot be modified. To modify parameters of a test session, delete the session and reconfigure it.

   • The IP address configured for a test session must be a unicast address. By default, the DSCP value and padding length of packets sent over a test session are 0 and 128, respectively.

   • The UDP port number of a Responder must be an unused port number. For example, if local-port is 4500 and IPSec NAT traversal is configured, the TWAMP Light service will be abnormal.

   • The VPN instance specified for a test session must have been created. When the VPN instance is deleted, the related test session is deleted. The value can be the name of a manually created VPN instance or a VPN instance automatically generated in the creation of a virtual system.

5. Optional: Run:

   twamp-light base-session max-rate max-rate

   The maximum packet rate of a TWAMP light measurement session is set.
