Remote-ping Overview 875
Source address (source-ip) For remote-ping tests other than DHCP test,
you can specify a source IP address for test
packets, which will be used by the server as
the destination address of response packets.
Source port (source-port) For remote-ping tests other than ICMP,
DHCP and DNS, you can specify a source
port number for test packets, which will be
used by the server as the destination port
number of response packets.
Test type (test-type)
■ You can use remote-ping to test a variety
of protocols, see Table 690 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
are 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)
■ 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)
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)
■ The probe timeout timer is started after
the remote-ping client sends out a test
packet.
■ 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.
dns This parameter is used to specify a DNS
domain name in a remote-ping DNS test
group.
dns-server 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.
