To create and configure a Two-Way Active Measurement Protocol Light reflector

Overview

You can enable or disable Two-Way Active Measurement Protocol (TWAMP) on a server, and view session and connection statistics. A TWAMP Light test needs to be pointed at a reflector on the correct UDP port in order to execute properly and generate valid results. A TWAMP Light reflector can be configured on a base routing instance or on a site. There can only be one reflector on a particular base routing instance or a site.
