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
1.
Enter system view.
2.
Create an NQA operation and
enter NQA operation view.
3.
Specify the ICMP echo type
and enter its view.
4.
Specify the destination address
of ICMP echo requests.
5.
(Optional.) Specify the payload
size in each ICMP echo request.
6.
(Optional.) Specify the string to
be filled in the payload of each
ICMP echo request.
7.
(Optional.) Specify the source
IP address of ICMP echo
requests.
8.
(Optional.) Specify the next hop
for ICMP echo requests.

Specify the IP address of the

Specify the source IP address:

Remarks
N/A
By default, no NQA operation
is created.
N/A
By default, no destination IP
address is specified.
The default setting is 100 bytes.
The default setting is the
hexadecimal number
00010203040506070809.
By default, no source IP address
is specified. The requests take
the primary IP address of the
outgoing interface as their
source IP address.
If you configure both source ip
and source interface, the most
recent configuration takes
effect.
The specified source interface
must be up. The source IP
address must be the IP address
of a local interface, and the
interface must be up.
Otherwise, no probe packets
can be sent out.
By default, no next hop is
configured.
