6.12. The SNMP Group

          -- the SNMP group

          -- Implementation of the SNMP group is mandatory for all
          -- systems which support an SNMP protocol entity.  Some of
          -- the objects defined below will be zero-valued in those
          -- SNMP implementations that are optimized to support only
          -- those functions specific to either a management agent or
          -- a management station.  In particular, it should be
          -- observed that the objects below refer to an SNMP entity,
          -- and there may be several SNMP entities residing on a
          -- managed node (e.g., if the node is hosting acting as
          -- a management station).
