How do I configure association between VRRP and NQA test instances on an S series switch

To configure association between VRRP and NQA test instances on an S series switch (except the S1700), perform the following operations:
1. Run the system-view command to enter the system view.
2. Run the interface interface-type interface-number[.subinterface-number ] command to enter the view of the interface to which the VRRP group belongs.
3. Run the vrrp vrid virtual-router-id track nqa admin-name test-name [ reduced value-reduced ] command to configure VRRP to track an NQA test instance.
By default, when the tracked NQA test instance becomes Down, the priority decreases by 10.
reduced value-reduced: specifies the value by which the VRRP priority reduces if the tracked NQA test instance becomes Down. The value ranges from 1 to 255. The minimum value of the priority is 0. Priority value 0 is reserved for special use. If a backup device receives a VRRP IPv6 Advertisement packet carrying the priority value of 0, the backup device immediately preempts the Master state.

Note: The NQA function is controlled by a license. The commands related to NQA can be used on a newly purchased device but does not take effect. To use the NQA function, apply for and purchase a license from a Huawei local office.

VRRP can also associate with BFD or a routing protocol to implement an active/standby switchover. For detailed configuration procedure, see section "Common VRRP Operations" at S1720&S2700&S3700&S5700&S6700&S7700&S9700 Common Operation Guide. The configuration method for the S9300 is the same as that for other switch models.
