Configuring a UDP Test Instance

Context

Before configuring a UDP test instance, configure a UDP server and ensure reachable routes between the UDP client and the UDP server.

To test the time for a specified port to respond to a UDP connection request, create a UDP test instance.

The NQA client also functions as the UDP client.

Procedure

Configure the UDP server.
1. Run system-view
  The system view is displayed.
2. Run nqa-server udpecho [ vpn-instance vpn-instance-name ] ip-address port-number
  The monitoring IP address and port number of the UDP server are configured.
Configure the NQA client.
1. Run system-view
  The system view is displayed.
2. Run nqa test-instance admin-name test-name
  An NQA test instance is created, and the NQA view is displayed.
3. Run test-type udp
  The test type is set to UDP.
4. Run destination-address ipv4 ipv4-address
  The destination address is configured.
5. Run destination-port port-number
  The destination port number is configured.
  
  By default, the destination port number in the UDP test is 7.
  
  If the configured destination port number is 7, 13, or 19, run the undo anti-attack udp-flood enable command on the server to disable UDP flood attack defense; otherwise, the server discards detection packets.
6. (Optional) Run the following commands as required to configure parameters for the UDP test.
  - Run description string
    
    A description is configured for the test instance.
  - Run frequency interval
    
    The test period is set for the NQA test instance.
  - Run timeout time
    
    The timeout period of a probe is set for the NQA test instance.
  - Run source-address ipv4 ipv4-address
    
    The source IP address is configured.
  - Run source-port port-number
    
    The source port number is configured.
  - Run ttl number
    
    The TTL value in the NQA test packet is set.
  - Run datafill fillstring
    
    The padding field is configured for the NQA test instance.
  - Run datasize size
    
    The packet size is set for the NQA test instance.
  - Run sendpacket passroute
    
    The NQA test instance is configured to send packets without searching the routing table.
  - Run probe-count number
    
    The number of probes in a test is set.
  - Run tos value
    
    Type of Service (TOS) is set for the test packet.
  - Run fail-percent percent
    
    The failure percentage is set for the NQA test instance.
  - Run interval seconds interval
    
    The interval at which test packets are sent is configured.
  - Run vpn-instance vpn-instance-name
    
    The VPN instance name is configured.
  - Run records history number
    
    The maximum number of historical records is set for the NQA test instance.
  - Run records result number
    
    The maximum number of result records is set for the NQA test instance.
  - Run agetime hh:mm:ss
    
    The aging time is set for the NQA test instance.
