876 CHAPTER 81: REMOTE-PING CONFIGURATION
Remote-ping
Configuration
The TCP/UDP/jitter tests need the cooperation of remote-ping client and
remote-ping Server, Other types of tests need to configure remote-ping client and
corresponding different servers.
Configuration on a
Remote-ping Server
You can enable both the remote-ping client and remote-ping server functions on a
Switch 7750, that is, the switch can serve as a remote-ping client and server
simultaneously.
HTTP operation string and version (http-string) This parameter is used to set the HTTP
operation string and version in an HTTP test.
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 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.
File name for FTP operation (filename) Name of a file to be transferred between
remote-ping client and FTP server
Number of jitter test packets to be sent per
probe (jitter-packetnum)
■ Jitter test is used to collect statistics
about delay jitter in UDP packet
transmission
■ In a jitter probe, the remote-ping client
sends a series of packets to the
remote-ping server at regular intervals
(you can set the interval). Once receiving
such a packet, the remote-ping server
marks it with a timestamp, and then
sends it back to the remote-ping client.
Upon receiving a packet returned, the
remote-ping client computes the delay
jitter time. The remote-ping client
collects delay jitter statistics on all the
packets returned in the test. So, the
more packets a jitter probe sends, the
more accurate the jitter statistics is, but
the longer time the jitter test costs.
Interval to send jitter test packets
(jitter-interval)
Each jitter probe will send multiple UDP test
packets at regular intervals (you can set the
interval). The smaller the interval is, the
faster the test is. But a too small interval
may somewhat impact your network.
Trap
■ A remote-ping test will generate a Trap
message no matter whether the test
successes or not. You can use the Trap
switch to enable or disable the output of
trap messages.
■ You can set the number of consecutive
failed remote-ping tests before Trap
output. You can also set the number of
consecutive failed remote-ping probes
before Trap output.
