RFC 2115                  Frame Relay DTE MIB             September 1997




     frErrTime OBJECT-TYPE

         MAX-ACCESS   read-only
         STATUS   current
         DESCRIPTION
            "The value of sysUpTime at which the error was
            detected."
         ::= { frErrEntry 4 }


     frErrFaults OBJECT-TYPE
         SYNTAX   Counter32
         MAX-ACCESS   read-only
         STATUS   current
         DESCRIPTION

            it was initialized."
         ::= { frErrEntry 5 }


     frErrFaultTime OBJECT-TYPE
         SYNTAX   TimeStamp
         MAX-ACCESS   read-only
         STATUS   current
         DESCRIPTION
            "The value of sysUpTime at the time when the interface
            was taken down due to excessive errors.  Excessive
            errors is defined as the time when a DLCMI exceeds the
            frDlcmiErrorThreshold number of errors within
            frDlcmiMonitoredEvents. See FrDlcmiEntry for further
            details."

     frameRelayTrapControl OBJECT IDENTIFIER ::= { frameRelayDTE 4 }

     -- the following highly unusual OID is as it is for compatibility
     -- with RFC 1315, the SNMP V1 predecessor of this document.
     frameRelayTraps OBJECT IDENTIFIER ::= { frameRelayDTE 0 }

     frTrapState OBJECT-TYPE

         MAX-ACCESS   read-write
         STATUS   current

         MAX-ACCESS   read-write
         STATUS   current
         DESCRIPTION
            "This variable indicates the number of milliseconds
            that must elapse between trap emissions.  If events
            occur more rapidly, the impementation may simply fail
            to trap, or may queue traps until an appropriate time."

         DESCRIPTION
            "This trap indicates that the indicated Virtual Circuit
            has changed state.  It has either been created or
            invalidated, or has toggled between the active and
            inactive states.  If, however, the reason for the state
            change is due to the DLCMI going down, per-DLCI traps
            should not be generated."

   Security issues for this MIB are entirely covered by the SNMP
   Security Architecture, and have not been expanded within the contents
   of this MIB.
