You can use remote-ping to test a variety of protocols, see
for details.
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.
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.
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.
For ICMP/UDP/jitter test, you can configure the size of test packets.
For ICMP test, the ICMP packet size refers to the length of
ECHO-REQUEST packets (excluding IP and ICMP headers)
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.
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.
It is equal to the argument "-h" in a ping command.
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.
This parameter is used to set the interval at which the remote-ping client
periodically performs the same test automatically.
The probe timeout timer is started after the remote-ping client sends
out a test packet.
This parameter is in seconds.
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.
This parameter is used to set the type of HTTP interaction operation
between remote-ping client and HTTP server.
This parameter is used to set the type of FTP interaction operation
between remote-ping client and FTP server.
The two parameters are used to set the username and password to be
used for FTP operation.
