                      The only value which may be set by a management
                      station is deleteTCB(12).  Accordingly, it is
                      appropriate for an agent to return a `badValue'
                      response if a management station attempts to set
                      this object to any other value.

                      If a management station sets this object to the
                      value deleteTCB(12), then this has the effect of
                      deleting the TCB (as defined in RFC 793) of the
                      corresponding connection on the managed node,
                      resulting in immediate termination of the
                      connection.

                      As an implementation-specific option, a RST
                      segment may be sent from the managed node to the
                      other TCP endpoint (note however that RST segments

                      causes an Idle peer to begin neighbor acquisition
                      and a non-Idle peer to reinitiate neighbor
                      acquisition.  A stop event causes a non-Idle peer
                      to return to the Idle state until a Start event
                      occurs, either via egpNeighEventTrigger or

          -- group is mandatory for that system.

          -- When Internet-standard definitions for managing
          -- transmission media are defined, the transmission group is
          -- used to provide a prefix for the names of those objects.

          -- Typically, such definitions reside in the experimental
          -- portion of the MIB until they are "proven", then as a
          -- part of the Internet standardization process, the
          -- definitions are accordingly elevated and a new object
          -- identifier, under the transmission group is defined. By
          -- convention, the name assigned is:
          --
          --     type OBJECT IDENTIFIER    ::= { transmission number }
          --
          -- where "type" is the symbolic value used for the media in
          -- the ifType column of the ifTable object, and "number" is
          -- the actual integer value corresponding to the symbol.
