Configuration procedure
1. Create VLANs, and assign corresponding ports to the VLANs. Configure the IP address of each
VLAN interface as shown in Figure 47 . (Details not shown)
2. Configure an NQA test group on Switch A.
<SwitchA> system-view
# Create an NQA test group with the administrator name admin and the operation tag test.
[SwitchA] nqa entry admin test
# Configure the test type as ICMP-echo.
[SwitchA-nqa-admin-test] type icmp-echo
# Configure the destination address as 10.1.2.2.
[SwitchA-nqa-admin-test-icmp-echo] destination ip 10.1.2.2
# Set the test frequency to 100 ms.
[SwitchA-nqa-admin-test-icmp-echo] frequency 100
# Configure reaction entry 1, specifying that five consecutive probe failures trigger the track module.
[SwitchA-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type
consecutive 5 action-type trigger-only
[SwitchA-nqa-admin-test-icmp-echo] quit
# Start the NQA test.
[SwitchA] nqa schedule admin test start-time now lifetime forever
3. Configure a track entry on Switch A.
# Configure track entry 1, and associate it with reaction entry 1 of the NQA test group (with the
administrator admin, and the operation tag test).
[SwitchA] track 1 nqa entry admin test reaction 1
4. Configure VRRP on Switch A.
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the priority of Switch A in VRRP group 1 to 110.
