light
Syntax
light { port number; }
Junos OS Hierarchy Level
[edit services rpm twamp server]
Description
Enable the Two-Way Active Measurement Protocol (TWAMP) server for light control on
the UDP port that reflects the test packets. If you want the default IANA port for
TWAMP (862), you do not need to configure the port option. To complete the
configuration for light control, you also need to configure the control-type
light
statement at either the Junos OS [edit services rpm twamp
client control-connection control-connection-name]
hierarchy level or the Junos OS Evolved [edit services monitoring twamp
client control-connection control-connection-name]
hierarchy level.
You configure the light statement because you want a stateless version of TWAMP where
test parameters are predefined instead of negotiated. All test packets received by
the server on a test port are reflected back and forgotten right away. If you want
to have a stateful TWAMP server for Junos OS Evolved, you should configure the
managed
statement at the [edit services monitoring twamp
server] hierarchy level instead. For Junos OS, if you want to have a stateful TWAMP
server, do not configure the light
statement for the TWAMP server,
because managed mode is the default. Because TWAMP light servers are stateless,
information about them is not included in the output of the show services
rpm twamp server connection
(Junos OS) or the show services
monitoring twamp server control-info
(Junos OS Evolved) operational
mode command; only information about managed servers is included.
