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.

SMT Version

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.
