Test parameter
Description
Test type (
test-type
)
z
You can use remote-ping to test a variety of protocols, see
Table 1-1
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.
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.
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.
