# Configure the NQA client to notify the feature of the operation failure if the number of consecutive
failed probes reaches 2.

TCP template configuration example
Network requirements
As shown in Figure 54, configure a TCP template for a feature to perform the TCP operation. The
operation tests whether Device A can establish a TCP connection to Device B.
Figure 54 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.
<DeviceB> system-view
[DeviceB] nqa server enable
# Configure a listening service to listen to the IP address 10.2.2.2 and TCP port 9000.
[DeviceB] nqa server tcp-connect 10.2.2.2 9000
4. Configure Device A:
# Create TCP template tcp.
<DeviceA> 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
# Configure the NQA client to notify the feature of the successful operation event if the number
of consecutive successful probes reaches 2.
[DeviceA-nqatplt-tcp-tcp] reaction trigger probe-pass 2
# Configure the NQA client to notify the feature of the operation failure if the number of
consecutive failed probes reaches 2.
[DeviceA-nqatplt-tcp-tcp] reaction trigger probe-fail 2
UDP template configuration example
Network requirements
As shown in Figure 55, configure a UDP template for a feature to perform the UDP operation. The
operation tests whether Device A can receive a response from Device B.
