The output shows that LB A uses 13 milliseconds to establish a TCP connection to port 9000 on the
NQA server.
UDP echo operation configuration example
Network requirements
As shown in Figure 56 , configure a UDP echo operation to test the round-trip time between LB A and LB
B. The destination port number is 8000.
Figure 56 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 LB B:
# Enable the NQA server, and configure a listening service to listen on the IP address 10.2.2.2
and UDP port 8000.
