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 payload fill string is 
hexadecimal number 
00010203040506070809. 

7. 

(Optional.) Specify the output 
interface for ICMP echo 
requests. 

out interface interface-type

 

interface-number 

By default, no output interface 
is specified. The NQA client 
determines the output interface 
based on the routing table 
lookup. 

8. 

(Optional.) Specify the source 
IP address of ICMP echo 
requests. 

•

 

Specify the IP address of the 
specified interface as the 
source IP address: 

source interface

 

interface-type

 

interface-number

 

•

 

Specify the source IP address:

source ip ip-address

 

By default, no source IP 
address is specified. The 
requests take the primary IP 
address of the output interface 
as their source IP address. 

If you configure both the 

source ip

 and 

source 

interface 

commands, 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. 

9. 

(Optional.) Specify the next 
hop for ICMP echo requests. 

next-hop ip-address

 

By default, no next hop is 
configured. 

 

Configuring the DHCP operation 

The DHCP operation measures whether or not the DHCP server can respond to client requests. 
DHCP also measures the amount of time it takes the NQA client to obtain an IP address from a 
DHCP server.
