If you execute the nqa entry command to enter the test group view with test type configured, you will 

enter the test type view of the test group directly. 

 

Configuring an NQA Test Group 

An ICMP echo test is used to test reachability of the destination host according to the ICMP echo reply 

or timeout information. An ICMP echo test has the same function with the ping command but has more 

abundant output information. You can use the ICMP echo test to locate connectivity problems in a 

network. 

Follow these steps to configure an ICMP echo test: 

Enter system view 

system-view 

— 

Enter NQA test group view 

nqa entry admin-name 
operation-tag 

— 

Configure the test type as 
ICMP echo and enter test type 
view 

type icmp-echo 

Required 

Configure the destination 
address for a test operation 

destination ip ip-address 

Required 

By default, no destination IP 
address is configured for a test 
operation. 

Configure the size of probe 
packets sent 

data-size size 

Optional 

100 bytes by default. 

Configure the filler string of a 
probe packet sent 

data-fill string 

Optional 

By default, the filler string of a 
probe packet is the hexadecimal 
number 
00010203040506070809. 

Specify a VPN instance 

vpn-instance instance 

Optional 

Not specified by default. 

Specify the IP address of an 
interface as the source IP 
address of an ICMP echo 
request 

source interface 
interface-type 
interface-number 

Optional 

By default, no interface address is 
specified as the source IP 
address of ICMP probe requests.

If you use the source ip 
command to configure the source 
IP address of ICMP echo probe 
requests, the source interface 
command is invalid. 

The interface specified by this 
command must be up. Otherwise, 
the probe will fail.
