Configuration procedure
1. Assign IP addresses to interfaces, as shown in Figure 50. (Details not shown.)
2. On Switch A, configure a static route, and associate the static route with track entry 1.
<SwitchA> system-view
[SwitchA] ip route-static 10.1.1.2 24 10.2.1.1 track 1
3. On Switch A, configure an ICMP echo operation:
# Create an NQA operation with the administrator name admin and operation tag test1.
[SwitchA] nqa entry admin test1
# Configure the NQA operation type as ICMP echo.
[SwitchA-nqa-admin-test1] type icmp-echo
# Specify 10.2.1.1 as the destination IP address.
[SwitchA-nqa-admin-test1-icmp-echo] destination ip 10.2.1.1
# Configure the operation to repeat every 100 milliseconds.
[SwitchA-nqa-admin-test1-icmp-echo] frequency 100
# Create reaction entry 1. If the number of consecutive probe failures reaches 5, collaboration is
triggered.
[SwitchA-nqa-admin-test1-icmp-echo] reaction 1 checked-element probe-fail
threshold-type consecutive 5 action-type trigger-only
[SwitchA-nqa-admin-test1-icmp-echo] quit
# Start the ICMP operation.
[SwitchA] nqa schedule admin test1 start-time now lifetime forever
4. On Switch A, create track entry 1, and associate it with reaction entry 1 of the NQA operation.
[SwitchA] track 1 nqa entry admin test1 reaction 1
Verifying the configuration
# Display information about all the track entries on Switch A.
[SwitchA] display track all
Track ID: 1

Duration: 0 days 0 hours 0 minutes 0 seconds
Notification delay: Positive 0, Negative 0 (in seconds)
Tracked object:
NQA entry: admin test1
Reaction: 1
# Display brief information about active routes in the routing table on Switch A.
[SwitchA] display ip routing-table
