UDP jitter operation configuration example
Network requirements
As shown in Figure 53 , configure a UDP jitter operation to test the jitter, delay, and round-trip time
between LB A and LB B.
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 LB B:
# Enable the NQA server and configure a listening service to listen on the IP address 10.2.2.2 and
UDP port 9000.
system-view
[LBB] nqa server enable
[LBB] nqa server udp-echo 10.2.2.2 9000
4. Configure LB A:
# Create a UDP jitter operation.
system-view
[LBA] nqa entry admin test1
[LBA-nqa-admin-test1] type udp-jitter
# Configure 10.2.2.2 as the destination IP address and port 9000 as the destination port.
