The nqa-server udpecho command configures a User Datagram Protocol (UDP) server for an NQA test.
The undo nqa-server udpecho command deletes the UDP server configured for an NQA test.
nqa-server udpecho [ vpn-instance vpn-instance-name ] { ip-address } port-number
undo nqa-server udpecho { [ vpn-instance vpn-instance-name ] { ip-address } port-number | all }
| Parameter | Description | Value |
|---|---|---|
| vpn-instance vpn-instance-name | Specifies the name of a VPN instance to which the UDP server belongs. | The value is a string of 1 to 31 characters. |
| all | Indicates a UDP server for all NQA test instances. | - |
| ip-address | Specifies the IP address of the NQA server for monitoring UDP services. | The value is in dotted decimal notation. |
| port-number | Specifies the port number of the NQA server for monitoring UDP services. | The value ranges from 1 to 65535. The configured port cannot be a well-known port or occupied by other modules. |
Usage Scenario
UDP packets are transmitted in a UDP-jitter or a UDP test. The test is used to obtain the packet delay, jitter, and packet loss ratio by comparing timestamps in the sent and response packets. A UDP server needs to be configured for an NQA test to respond to probe packets.
Configuration Impact
Running the undo nqa-server udpecho all command will delete the UDP server for all NQA instances.
Precautions
No matter the version number of the UDP-jitter test packet is 1 or 2, you need to configure the NQA server. Otherwise, the UDP-jitter test instance will fail due to timeout.
