   DESCRIPTION
     "This module defines a schema to access SSR Layer 2 processing subsystem.
      This mib is no longer supported on ssr platforms. features of this 
      mib now exist in standard mibs. RMON I RFC 1757 provides 
      Layer 2 information and ctron-ssr-policy mib to program filter tables."

   REVISION "9909220000Z"
   DESCRIPTION "Firmware release 3.0 introduces full rmon I and II. this
                enterprise mib is now obsolete."

        The highest priority class is reserved for router control traffic, 
        which leaves three classes, high, medium, and low for normal
        data flows. Buffered traffic in higher priority classes is sent ahead 
        of pending traffic in lower priority classes, which allows latency 
        and throughput demands to be maintained for the higher priority traffic. 
        To prevent low priority traffic from waiting indefinitely as higher 
        priority traffic fills the wire, a weighted fair queuing mechanism provides 
        adjustable minimum bandwidth guarantees at each output port, thereby ensuring
