• Enable sending ICMP destination unreachable packets on the destination device. If the destination
device is an H3C device, use the ip unreachables enable command.
For more information about the ip ttl-expires enable and the ip unreachable enable command, see
Layer 3—IP Services Command Reference.
To configure the path jitter 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 operation is
created.
3. Specify the path jitter type and
enter its view.
type path-jitter N/A
4. Specify the destination address
of ICMP echo requests.
destination ip ip-address
By default, no destination IP address
is specified.
5. Specify the payload size in each
ICMP echo request.
data-size size The default setting is 100 bytes.
6. Specify the string to be filled in
the payload of each ICMP echo
request. data-fill string
The default setting is the hexadecimal
number
00010203040506070809.
7. Specify the source IP address of
ICMP echo request.
source ip ip-address
By default, no source IP address is
specified.
The source IP address must be the IP
address of a local interface and the
interface must be up.
8. Specify the number of ICMP
echo requests to be sent in a
path jitter operation.
probe packet-number
packet-number
The default setting is 10.
9. Specify the interval for sending
ICMP echo requests. probe packet-interval
packet-interval
The default setting is 20 milliseconds.
10. Specify how long the NQA
client waits for a response from
the server before it regards the
response times out.
probe packet-timeout
packet-timeout The default setting is 3000
milliseconds.
11. (Optional.) Specify an LSR path. lsr-path ip-address&<1-8>
By default, no LSR path is specified.
The path jitter operation uses the
tracert to detect the LSR path to the
destination, and sends ICMP echo
requests to each hop on the LSR.
12. (Optional.) Perform the path
jitter operation on destination
only.
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:
