[DeviceA-nqatplt-dns-dns] reaction trigger probe-pass 2
# If the number of consecutive probe failures reaches 2, the operation fails. The NQA client notifies the
feature of the operation failure.

TCP template configuration example
Network requirements
As shown in Figure 53 , configure a TCP template for a feature to perform the TCP operation to test
whether Device A can establish a TCP connection to Device B and process the server's response.
Figure 53 Network diagram
Configuration procedure
1. Assign each interface an IP address. (Details not shown.)
2. Configure static routes or a routing protocol to make sure the devices can reach each other.
(Details not shown.)
3. Configure Device B:
# Enable the NQA server, and configure a listening service to listen to the IP address 10.2.2.2 and
TCP port 9000.
system-view
[DeviceB] nqa server enable
[DeviceB] nqa server tcp-connect 10.2.2.2 9000
4. Configure Device A:
# Create TCP template tcp.
system-view
[DeviceA] nqa template tcp tcp
# Configure 10.2.2.2 as the destination IP address and port 9000 as the destination port.
[DeviceA-nqatplt-tcp-tcp] destination ip 10.2.2.2
[DeviceA-nqatplt-tcp-tcp] destination port 9000
# If the number of consecutive successful probes reaches 2, the operation succeeds. The NQA
client notifies the feature of the successful operation event.

# If the number of consecutive probe failures reaches 2, the operation fails. The NQA client
notifies the feature of the operation failure.
