  DESCRIPTION
     "The default length of time, in seconds, that the master
      agent should allow to elapse after dispatching a message
      to a session before it regards the subagent as not
      responding.  This is a system-wide value that may
      override the timeout value associated with a particular
      session (agentxSessionTimeout) or a particular registered
      MIB region (agentxRegTimeout).  If the associated value of
      agentxSessionTimeout and agentxRegTimeout are zero, or
      impractical in accordance with implementation-specific
      procedure of the master agent, the value represented by
      this object will be the effective timeout value for the

master agent to await a response to a dispatch from a
