Configuring the UDP echo operation

The UDP echo operation measures the round-trip time between the client and a UDP port on the NQA server.

The UDP echo operation requires both the NQA server and the NQA client. Before you perform a UDP echo operation, configure a UDP listening service on the NQA server. For more information about the UDP listening service configuration, see "Configuring the NQA server."

To configure the UDP echo operation:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Create an NQA operation and enter NQA operation view.

nqa entry admin-name operation-tag

By default, no NQA operations exist.

3. Specify the UDP echo type and enter its view.

type udp-echo

N/A

4. Specify the destination address of UDP packets.

destination ip ip-address

By default, no destination IP address is specified.

The destination address must be the same as the IP address of the listening service configured on the NQA server.

5. Specify the destination port of UDP packets.

destination port port-number

By default, no destination port number is specified.

The destination port number must be the same as the port number of the listening service on the NQA server.

6. (Optional.) Set the payload size for each UDP packet.

data-size size

The default setting is 100 bytes.

7. (Optional.) Specify the payload fill string for UDP packets.

data-fill string

The default payload fill string is the hexadecimal string 00010203040506070809.

8. (Optional.) Specify the source port of UDP packets.

source port port-number

By default, no source port number is specified.

9. (Optional.) Specify the source IP address of UDP packets.

source ip ip-address

By default, the packets take the primary IP address of the output interface as their source IP address.

The source IP address must be the IP address of a local interface, and the interface must be up. Otherwise, no UDP packets can be sent out.
