Test type (test-type) 

z 

You can use remote-ping to test a variety of protocols, see 

for details. 

z 

To perform a type of test, you must first create a test group of this 
type. One test group can be of only one remote-ping test type. 

z 

If you modify the test type of a test group using the test-type 
command, the parameter settings, test results, and history records of 
the original test type will be all cleared. 

Number of probes per 
test (count) 

For tests except jitter test, only one test packet is sent in a probe. In a 
jitter test, you can use the jitter-packetnum command to set the number 
of packets to be sent in a probe. 

Packet size (datasize) 

z 

For ICMP/UDP/jitter test, you can configure the size of test packets. 

z 

For ICMP test, the ICMP packet size refers to the length of 
ECHO-REQUEST packets (excluding IP and ICMP headers) 

Padding string for the 
test packet (datafill) 

In ICMP, UDP and jitter tests, the system should stuff the data field of 
each transmitted ICMP message. The stuffing character string ranges 
from 1 to 230 characters, including spaces. 

If the size of a test datagram is smaller than that of the configured 
stuffing character string, only a portion of the string will be used for 
stuffing. If the size of the test datagram is larger, the string will be used 
cyclically for stuffing. Suppose a stuffing string, “abcde”, is configured. If 
the test datagram size is 3, only “abc” will be used for stuffing; if it is 8, 
the string “abcdeabc" will be used. 

Routing table 
bypass(sendpacket 
passroute) 

With routing table bypass, a remote host can bypass the normal routing 
tables and send ICMP packets directly to a host on an attached network. 
If the host is not on a directly-attached network, an error is returned. You 
can use this function when pinging a local host on an VLAN interface that 
has no route defined.  

TTL of remote-ping test 
packets (ttl) 

It is equal to the argument “-h” in a ping command. 

Maximum number of 
history records that can 
be saved 
(history-records) 

This parameter is used to specify the maximum number of history 
records that can be saved in a test group. When the number of saved 
history records exceeds the maximum number, remote-ping discards 
some earliest records. 

Automatic test interval 
(frequency) 

This parameter is used to set the interval at which the remote-ping client 
periodically performs the same test automatically. 

Probe timeout time 
(timeout) 

z 

The probe timeout timer is started after the remote-ping client sends 
out a test packet. 

z 

This parameter is in seconds. 

Type of service (tos) 

Type of service is the value of the ToS field in IP header in the test 
packets. 

This parameter is used to specify a DNS domain name in a remote-ping 
DNS test group. 

This parameter is used to set the DNS server IP address in a 
remote-ping DNS test group. 

HTTP operation type 
(http-operation) 

This parameter is used to set the type of HTTP interaction operation 
between remote-ping client and HTTP server. 

FTP operation type 
(ftp-operation) 

This parameter is used to set the type of FTP interaction operation 
between remote-ping client and FTP server. 

FTP login username and 
password (username 
and password) 

The two parameters are used to set the username and password to be 
used for FTP operation.
