FDDI Applications

Non-Op-Dup	The ring is not operational; the address of the MAC
	under control of the SMT entity has been found to
	duplicate that of another MAC on the ring. The duplicate
	address condition prevented ring recovery and
	initialization after a claim and beacon process. This state
	will not occur unless you are using locally- administered
	addresses, as factory-set MAC addresses are guaranteed
	to be unique.
Ring-Op-Dup	The ring is operational; however, the address of the MAC
	under control of the SMT entity has been found to
	duplicate that of another MAC on the ring. Corrective
	actions will be attempted before the duplicate address
	condition causes ring initialization to fail after the claim
	and beacon recovery process. Like Non-Op-Dup, this
	state will not occur unless you are using
	locally-administered addresses.
Directed	The beacon process did not complete within seven
	seconds. The selected SMT has directed the controlled
	MAC to send beacon frames to notify the other stations
	that a serious problem exists on the ring, and a Trace
	state is soon to follow.
Trace	A problem exists on the ring which could not be
	corrected during the beaconing process, and a Trace has
	been initiated. During a Trace (or Path Test), the SMT
	sends a signal that forces its nearest upstream neighbor
	to remove from the ring and conduct a self-test. If the
	ring does not recover, each subsequent upstream station
	will be forced to remove from the ring and conduct
	self-tests until the problem has been corrected. While the
	test is being conducted, ring management re-enters the
	isolated state.

Displays the HSIM-F6’s operational Station Management (SMT) version. SMT provides the system management services for the FDDI protocols, including connection management, node configuration, error recovery, and management frame encoding. SMT frames have a version ID field that identifies the structure of the SMT frame Info field. The version number is included in the SMT frame so that a receiving station can determine whether or not its SMT version is able to communicate with the SMT version of another station. Knowing the version number allows the stations to handle version mismatches. Each FDDI station supports a range of SMT versions. The supported version range is identified within the ietf-fddiMIB by two smtTable attributes: snmpFddiSMTLoVersionId and snmpFddiSMTHiVersionId. If a received frame is not within the supported version range, the frame is discarded.
