requests to each hop on the LSR.
12. (Optional.) Perform the path
jitter operation only on the
destination address.
target-only
By default, the path jitter operation is
performed on each hop on the path
to the destination.
Configuring optional parameters for the NQA operation
Unless otherwise specified, the following optional parameters apply to all types of NQA operations.
To configure optional parameters for an NQA operation:
Step Command Remarks
1. Enter system view.

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

3. Specify an NQA
operation type and enter
its view.

text By default, no description is configured.
5. Specify 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 operations, the default setting is
0 milliseconds. 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 the 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. Specify the probe
timeout time.
probe timeout
timeout
The default setting is 3000 milliseconds.
This command is not available for the
path jitter, UDP jitter, and voice
operations.
8. Specify the TTL for probe
packets.
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
