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:

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 source
interface and the source IP
address of ICMP echo
requests.
• Specify the source interface:
source interface interface-type
interface-number
• Specify the source IP address:
source ip ip-address
By default, no source interface or
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 source ip
command 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.
8. (Optional.) Specify the next
hop for ICMP echo requests.
next-hop ip-address
By default, no next hop is
configured.
Configuring the UDP echo operation
The UDP echo operation measures the round-trip time between the client and a specific UDP port on the
NQA server.
