    Historical PM Counters for Optical Interfaces on MX Series and PTX Series Routers

    PSM supports the retrieval and display of historical PMs from optical interfaces on MX Series and PTX Series routers. The actual PMs supported depend on the configuration and the software running on the router, and may include some or all of the following:
