COPS Connection Between JUNOSe Routers and the SAE
All SDX releases support operation of the SDX software on JUNOSe routers. For a list of which JUNOSe releases a particular SDX release supports, see the SDX Release Notes.
Configuring the SDX client on a JUNOSe router opens a Common Open Policy Service (COPS) protocol layer connection to the SAE. When the SDX client software establishes a TCP/IP connection to the SAE, the SAE starts to manage the JUNOSe router. Subsequently, the SDX client sends configuration changes made on the JUNOSe router to the SAE, and the SAE updates SDX configurations for services and policies accordingly.
The SAE supports two versions of COPS:
The version of COPS that you use depends on the version of COPS that your JUNOSe router supports. When you set up your JUNOSe router to work with the SAE, you enable either COPS-PR mode or COPS XDR mode.
