Configuring optional parameters for the NQA operation

Unless otherwise specified, the following optional parameters apply to all types of NQA operations.

The parameter settings take effect only on the current operation.

To configure optional parameters for an NQA 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 an NQA operation type and enter its view.

type { dhcp | dlsw | dns | ftp | http | icmp-echo | icmp-jitter | path-jitter | snmp | tcp | udp-echo | udp-jitter | udp-tracert | voice }

N/A

4. Configure a description.

description text

By default, no description is configured.

5. Set the interval at which the NQA operation repeats.

frequency interval

For a voice or path jitter operation, the default setting is 60000 milliseconds.

For other types of operations, the default setting is 0 milliseconds, and only one operation is performed.

If the operation is not completed when the interval expires, the next operation does not start.

6. Specify the probe times.

probe count times

By default:

  • In an UDP tracert operation, the NQA client performs three probes to each hop to the destination.

  • In other types of operations, the NQA client performs one probe to the destination per operation.

This command is not available for the path jitter and voice operations. Each of these operations performs only one probe.

7. Set the probe timeout time.

probe timeout timeout

The default setting is 3000 milliseconds.

This command is not available for the ICMP jitter, path jitter, UDP jitter, or voice operations.

8. Set the maximum number of hops that the probe packets can traverse.

ttl value

The default setting is 30 for probe packets of the UDP tracert operation, and is 20 for probe packets of other types of operations.

This command is not available for the DHCP or path jitter operation.

9. Set the ToS value in the IP header of probe packets.

tos value

The default setting is 0.

10. Enable the routing table bypass feature.

route-option bypass-route

By default, the routing table bypass feature is disabled.

This command is not available for the DHCP and path jitter operations.

11. Specify the VPN instance where the operation is performed.

vpn-instance vpn-instance-name

By default, the operation is performed on the public network.
