Description
Configure the Two-Way Active Measurement Protocol (TWAMP) client or server settings on all M Series and T Series routers that support Multiservices PICs (running in either Layer 2 or Layer 3 mode), MX Series routers, ACX routers, EX4300 Switches, PTX Series routers, EX9200 Series switches, and QFX10000 Series switches.
TWAMP is an open protocol for measurement of two-way metrics. The host that initiates the TCP connection takes the roles of the control-client and (in the two-host implementation) the session-sender. Such a device is also called the TWAMP client. The host that acknowledges the TCP connection accepts the roles of a server and (in the two-host implementation) and the session-reflector. Such a device is also called the TWAMP server. The TWAMP-Test messages are exchanged between the session-sender and the session-reflector, and the TWAMP-Control messages are exchanged between the control-client and the server.
The following addresses cannot be used for the client-list source IP
address used for probes:
-
0.0.0.0
-
127.0.0.0/8 (loopback)
-
224.0.0.0/4 (multicast)
-
255.255.255.255 (broadcast)
