RESPONDER TIME RESPONDER
CONFIGURATION
The RTR (Responder Time Reporter) service gives the possibility to execute commands according to
a specific RTR watcher configured. More precisely, RTR functionality allows the configuration of
probes to be sent to a pre-configured address in order to measure performance and network
latency times.
With the commands:
set rtr frequency <seconds>
set rtr timeout <millisec>
set rtr lifetime <seconds>
set rtr pkt-size <bytes>
set rtr tos <value>
it is possible to configure the frequency (in seconds) to send probes, the latency (in milliseconds)
for the reply to the probe, the duration of the probe (0 corresponds to an infinite duration), the size
of the probe packet (in bytes), the Type of Service value (from 2 to 254).
It is also possible to choose that the probe is created from an i icmp echo request, operation,
from the transmission of a UDP packet or from a request of connection to a given service, towards a
given destination address. The commands are:
set rtr type ipIcmpEcho dst-addr <value> [src-addr <value>]
it defines that the probe is created from an ICMP echo request packet towards the address dst-
addr (and optionally with source address src-addr).
set rtr type udpEcho dst-addr <value> <dst-port> <value> [src-addr <value> [src-addr <value>]]
It defines that the probe is created from a UDP packet towards the address dst-host and port dst-
port. It is possible to specify the src-addr source address also, with which the packet must be
sent. In this case it is possible to specify the src-port source port also. Like:
set rtr type udpEcho dst-addr 192.168.206.1 dst-port 1234 src-addr 192.168.206.38 src-port 11000
set rtr type tcpConnect dst-addr <value> <dst-port> <value> [ src-addr <value> [src-addr <value>]]
tells that the probe is made by a connection request to the dst-port service towards dst-host
address.
set rtr type udpJitter dst-addr <value> <dst-port> <value> [src-addr <value> [src-addr <value>]]
defines an operation according to the protocol Cisco IP SLA UDP-Jitter, to the dst-host address and
dst-port port. You can also specify the src-addr source address and src-port source port, to
which the packet has to be send.
With the command:
set rtr threshold N
A threshold value is established. When this value is exceeded, all the actions configured with the
command set rtr reaction-event are executed (the command is described later).
set rtr reaction-event ifFailure <command>
