(Optional) Associating IPv6 Static Routes with NQA

(Optional) Associating IPv6 Static Routes with NQA

Pre-configuration Tasks

Before associating IPv6 static routes with NQA, complete the following task:

  • Configure link layer parameters and IPv6 addresses for interfaces to ensure that the link layer protocol on the interfaces is Up.

Procedure

  1. Configure an ICMP NQA test instance.
    1. Run system-view

      The system view is displayed.

    2. Run nqa test-instance admin-name test-name

      An NQA test instance is created, and the view of the test instance is displayed.

    3. Run test-type icmp

      The test type is set to ICMP.

    4. Run destination-address ipv6 ipv6-address

      A destination address is configured.

      In an NQA test instance, you can specify an NQA server by running the destination-address command to configure a destination address for the NQA test instance.

    5. (Optional) Run frequency interval

      The interval for automatically performing an NQA test is set.

      By default, no interval is set, that is, only one test is performed.

    6. (Optional) Run probe-count number

      The number of probes to be sent each time is set for the NQA test instance.

      By default, the number of probes is 3.

      By sending probes multiple times in an NQA test instance, you can accurately estimate network quality based on the collected statistics.

    7. (Optional) Run interval seconds interval

      The interval at which probe packets are sent is set.

      The default interval is 4 seconds for an NQA ICMP test instance.

      Set the interval based on network quality:

      • If network quality is unsatisfactory, increase the interval to prevent network deterioration caused during the operation of test instances.
      • If network quality is satisfactory, decrease the interval to accelerate the running speed of test instances.

    8. (Optional) Run timeout time

      A timeout period is set for the NQA test instance.

      The default timeout period is 3 seconds.

    9. (Optional) Run fail-percent percent

      A probe failure percentage is set for the NQA test instance.

      The default probe failure percentage is 100%. That is, the test is considered failed only when all probes fail. You can set a probe failure percentage based on network quality.

      NOTE:

      no result may be returned if the following condition is met:

      Interval at which the NQA test is automatically performed ≤ Interval at which probe packets are sent x (Number of sent packets - 1) + Timeout period

      The number of packets sent in an NQA ICMP test instance is the number of probes specified using the probe-count number command.

    10. Run start

      The NQA test instance is started.

      The start command can configure an NQA test instance to be started immediately, at a specified time, or after a specified delay. You can perform one of the following operations as required:
      • Run start now [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ]

        The NQA test instance is started immediately.

      • Run start at [ yyyy/mm/dd ] hh:mm:ss [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ]

        The NQA test instance is started at a specified time.

      • Run start delay { seconds second | hh:mm:ss } [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ]

        The NQA test instance is started after a specified delay.

      • Run start daily hh:mm:ss to hh:mm:ss [ begin { yyyy-mm-dd | yyyy/mm/dd } ] [ end { yyyy-mm-dd | yyyy/mm/dd } ]

        The NQA test instance is started every day.

    11. Run commit

      The configuration is committed.

    12. Run quit

      Return to the system view.

  2. Associate static routes with an NQA test instance.
    1. Run ipv6 route-static dest-ipv6-address prefix-length { interface-type interface-number [ nexthop-ipv6-address ] | vpn-instance vpn-instance-name nexthop-ipv6-address | nexthop-ipv6-address } [ preference preference | tag tag ]* track nqa admin-name test-name [ description text ]

      IPv6 static routes are associated with an NQA test instance.

      NOTE:

      The destination address of an NQA test instance cannot be the destination address of an associated IPv6 static route.

      If the IPv6 static route associated with an NQA test instance is associated with another NQA test instance, the IPv6 static route is disassociated from the first NQA test instance.

    2. Run commit

      The configuration is committed.

Verifying the Configuration

After IPv6 static routes are associated with NAQ, run the following commands to verify the configuration.

  • Run the display current-configuration | include nqa command to check the configuration of association between static routes and NQA.

  • Run the display nqa results [ test-instance admin-name test-name ] command to check the NQA test result.

    The NQA test result cannot be displayed automatically. You must run the display nqa results command to view the NQA test result. By default, the command output shows the results of the latest five NQA tests.
