Configuring threshold monitoring

Configuring the NQA statistics collection function

Configuring the saving of NQA history records

(Required.) Scheduling the NQA operation on the NQA client

Configuring the ICMP echo operation

The ICMP echo operation measures the reachability of a destination device. It has the same function as

the

ping

command, but provides more output information. In addition, if multiple paths exist between the

source and destination devices, you can specify the next hop for the ICMP echo operation.
The ICMP echo operation is not supported in IPv6 networks. To test the reachability of an IPv6 address,

use the

ping ipv6

command. For more information about the command, see

Network Management and

Monitoring Command Reference.

To configure the ICMP 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 operation is
created.

3.

Specify the ICMP echo type
and enter its view.

type icmp-echo

N/A

4.

Specify the destination
address of ICMP echo

requests.

destination ip

ip-address

By default, no destination IP
address is specified.

5.

(Optional.) Specify the

payload size in each ICMP
echo request.

data-size

size

The default setting is 100 bytes.

6.

(Optional.) 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.

(Optional.) Specify the
output interface for ICMP

echo requests.

out interface

interface-type

interface-number

By default, the output interface for
ICMP echo requests is not

specified. The NQA client
determines the output interface

based on the routing table lookup.
