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.
