Toronto IETF, July 1994

Presentation presented by Timon Sloane and Karl Auerbach on possible
changes for RMON, in particular a Packet Generation capability.




Packet Generation Group

	PktGenEntry ::= SEQUENCE {
		pktGenIndex		INTEGER,
		pktGenFrameData		OCTET STRING (SIZE (1..1518)),
		pktGenCount		INTEGER (1..10000),
		pktGenInterval		INTEGER (0..5000),	-- units: ms
		pktGenCalcCRC		INTEGER,
		pktGenInterface		INTEGER,		-- ifIndex
		pktGenFire		INTEGER,
		pktGenOwner		OwnerString,
		pktGenStatus		rowStatus
	}

	pktGenCalcCRC OBJECT-TYPE
		SYNTAX INTEGER {	probe-calculates-crc (1),
					crc-bytes-transmitted-as-is (2)
				}
		ACCESS read-write
		STATUS mandatory
		DESCRIPTION
			"If this object has the value 'probe-calculates-crc'
			then the probe will calculate the MAC layer CRC
			and overwrite the bytes contained in 'pktGenFrameData'
			that are in the same position as the CRC bytes.

			If this object has the value
			'crc-bytes-transmitted-as-is', then the probe will
			not calculate and overwrite the CRC bytes in the
			'pktGenFrameData'.

			For probes than cannot transmit packets without
			calculating and generating a CRC, a set of this
			object to 'crc-bytes-transmitted-as-is' will
			result in a badValue error."
		::= { pktGenEntry x }

	pktGenFire OBJECT-TYPE
		SYNTAX INTEGER {	idle (1),
					fire (2),
					busy (3)
				}
		ACCESS read-write
		STATUS mandatory
		DESCRIPTION
			"This object, when read, will always return the
			value 'idle' or 'busy'.  If this object is set to the
			value 'fire', the agent will transmit the appropriate
			number of data link frames....

			If this object has the value 'busy', then the
			probe is currently transmitting frames and will
			return a badValue if the manager attempts to set
			this object to 'fire'.
