Configuring the TWAMP Light Controller

Configuring the TWAMP Light Controller

Procedure

  1. Configure the TWAMP Light Client.

    1. Run the system-view command to enter the system view.
    2. Run the nqa twamp-light command to create the TWAMP Light service and enter the TWAMP Light view.

      By default, the TWAMP Light service is not created.

    3. Run the client command to enable the TWAMP Light Client function and enter the TWAMP Light Client view.

      By default, the TWAMP Light Client function is disabled.

    4. Run the test-session session-id sender-ip sender-ip-address reflector-ip reflector-ip-address sender-port sender-port reflector-port reflector-port [ vpn-instance vpn-instance-name ] [ dscp dscp-value | padding padding-length | description description ] * command to create a measurement session.

      By default, no measurement session is created.

      • After a session is created, its parameters cannot be modified. To modify the session parameters, delete the session and create it again.

      • The IP address must be a unicast address. By default, the DSCP field in a sent packet is 0 and the packet padding length is 128.

      • The UDP port of the sender must be a port that is not occupied.

      • All the parameters related to the VPN instance must exist. When the VPN instance is deleted, the related measurement instance is also deleted.

      • To configure a session with multiple DSCP values, you can specify different UDP port numbers for sender. The following are two examples:

        • Session 1: test-session 1 sender-ip 1.1.1.1 reflector-ip 2.2.2.2 sender-port 1025 reflector-port 1025 dscp 3

        • Session 2: test-session 2 sender-ip 1.1.1.1 reflector-ip 2.2.2.2 sender-port 1026 reflector-port 1025 dscp 6

  2. Configure the TWAMP Light Sender.

    1. Run the system-view command to enter the system view.
    2. Run the nqa twamp-light command to enter the TWAMP Light view.

      By default, the TWAMP Light service is not created.

    3. Run the sender command to enable the TWAMP Light Sender function and enter the TWAMP Light Sender view.

      By default, the TWAMP Light Sender function is disabled.

      NOTE:
      If you have not quitted from the TWAMP Light Client view, you can also run the sender command to enter the TWAMP Light Sender view.
    4. Start TWAMP Light performance measurement.

      The controller starts performance measurement in on-demand mode or continual mode. To measure performance only once, enable on-demand measurement. To measure performance continuously, enable continual measurement.

      • To enable on-demand measurement, run the test start test-session session-id { duration duration | packet-count packet-count } [ period { 10 | 100 | 1000 | 30000 } ] [ time-out time-out ] command.

      • To enable continual measurement, run the test start-continual test-session session-id [ period { 10 | 100 | 1000 | 30000 } ] [ time-out time-out ] command.

        By default, the packet sending interval is 100 ms and timeout interval is 5s.

        NOTE:
        • On-demand measurement: indicates that performance measurement is started manually within the specified time range aiming at network fault diagnosis. It is a one-off measurement in the diagnosis period. The measurement stops when the specified interval is expired or a certain number of packets are sent.
        • Continual measurement: indicates the measurement is performed continuously.
        • If you enable continual measurement during an on-demand measurement, the on-demand measurement immediately stops and the continual measurement starts.
