Category: IETF Standards

Description: Implements FDDI MIB objects for ring monitoring, SMT frames, and station management per RFC 1285.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is RFC1285-MIB?

RFC1285-MIB is an IETF standards-track FDDI Station Management (SMT 7.3) MIB, an earlier version of FDDI management objects later superseded by RFC 1512. It defines objects for FDDI ring status, SMT (Station Management) frames, and station-level configuration and state across the MAC, PHY (PORT), and SMT layers of an FDDI station. It is used to monitor the operational health of FDDI ring hardware and firmware: ring state and station status objects reveal whether a station is properly inserted and passing traffic on the dual ring, while SMT frame counters can expose neighbor notification or ring-management protocol problems that precede a ring wrap or isolation. It is a self-contained IETF standard that was later effectively replaced in most deployments by the newer FDDI MIB in RFC 1512, though both describe the same underlying SMT/MAC/PORT FDDI architecture. It would be deployed on FDDI ring stations, concentrators, and router FDDI interfaces in legacy fiber-ring campus/backbone networks. Engineers can download the RFC1285-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RFC1285-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
FDDI ring stations, concentrators, and router FDDI interfaces

Monitoring Examples

No sample_objects were supplied for this module in the available source, so specific object names cannot be cited directly; based on the RFC 1285 SMT structure, an administrator would be expected to poll station and ring-state objects to detect a station transitioning out of the ring-operational state, and SMT frame counters to spot abnormal neighbor notification activity, though exact object identifiers used are not confirmed from available data.

What Can Be Monitored

FDDI ring/station operational state
SMT frame counters
port connection state

The MAC identified by a particular value of this index is that identified by the same value of an ifIndex object instance. That is, if a MAC is associated with the interface whose value of ifIndex in the Internet-Standard MIB is equal to 5, then the value of snmpFddiMACIndex shall also equal 5. The value for each MAC must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.

INT snmpFddiMACFrameErrorThreshold	1.3.6.1.2.1.10.15.2.2.1.23	INTEGER	read-only	A threshold for determining when a MAC Condition report should be generated. The condition is true when the ratio, ((delta snmpFddiMACLostCt + delta snmpFddiMACErrorCt) / (delta snmpFddiMACFrameCt + delta snmpFddiMACLostCt)) x 2**16. exceeds the threshold. It is used to determine when a station has an unacceptable frame error threshold. The sampling algorithm is implementation dependent. Any attempt to set this variable to a value of less than one shall result in a badValue error. Those who are familiar with the SNMP management framework will recognize that thresholds are not in keeping with the SNMP philosophy. However, this variable is supported by underlying SMT implementations already and maintaining this threshold should not pose an undue additional burden on SNMP agent implementors.
INT snmpFddiMACFrameErrorRatio	1.3.6.1.2.1.10.15.2.2.1.24	INTEGER	read-only	This attribute is the actual ratio, ((delta snmpFddiMACLostCt + delta snmpFddiMACErrorCt) / (delta snmpFddiMACFrameCt + delta snmpFddiMACLostCt)) x 2**16.

OID snmpFddiMACChipSet	1.3.6.1.2.1.10.15.2.2.1.29	OBJECT IDENTIFIER	read-only	This object identifies the hardware chip(s) which is (are) principally responsible for the implementation of the MAC function. A few OBJECT IDENTIFIERS are identified elsewhere in this memo. For those The assignment of additional OBJECT IDENTIFIERs to various types of hardware chip sets is managed by the IANA. For example, vendors whose chip sets are not defined in this memo may request a number from the Internet Assigned Numbers Authority (IANA) which indicates the assignment of a enterprise specific subtree which, among other things, may be used to allocate OBJECT IDENTIFIER assignments for that enterprise's chip sets. Similarly, in the absence of an appropriately assigned OBJECT IDENTIFIER in this memo or in an enterprise specific subtree of a chip vendor, a board or system vendor can request a number for a subtree from the IANA and make an appropriate assignment. It is desired that, whenever possible, the same OBJECT IDENTIFIER be used for all chips of a given type. Consequently, the assignment made in this memo for a chip, if any, should be used in preference to any other assignment and the assignment made by the chip manufacturer, if any, should be used in preference to assignments made by users of those chips. If the hardware chip set is unknown, the object identifier unknownChipSet OBJECT IDENTIFIER ::= { 0 0 } is returned. Note that unknownChipSet is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.
INT snmpFddiMACAction	1.3.6.1.2.1.10.15.2.2.1.30	INTEGER	read-write	This object, when read, always returns a value of other(1). The behavior of setting this variable to each of the acceptable values is as follows: Other: Results in a badValue error. enableLLCService: enables MAC service to higher layers. disableLLCService: disables MAC service to higher layers. connectMAC: connect this MAC in station. disconnectMAC: disconnect this MAC in station. Attempts to set this object to all other values results in a badValue error.

INT snmpFddiPORTPathsRequested	1.3.6.1.2.1.10.15.4.2.1.8	INTEGER	read-write	A value that indicates the desired association(s) of the port with a station PATH. The 'Primary' Path is the default. The value of 'Secondary' is only meaningful for S (slave) or M (master) PORT PC-Types. This value effects the setting of the CF_Insert_S, and CF_Insert_L flags (refer to ANSI Section 9.4.3). If the 'Primary' PATH is present, then the Primary PATH (the default PATH) is selected. If the 'Secondary' PATH is present and the 'Primary' PATH is not present, then the CF_Insert_S flag is set. If the 'Local' PATH is sent and neither the 'Primary' or 'Secondary' PATHs are sent, then the CF_Insert_L flag is set. The value is a sum. This value initially takes the value zero, then for each type of PATH desired, 2 raised to a power is added to the sum. The powers are according to the following table: Path Power Primary 0 Secondary 1 Local 2 Isolated 3

CTR snmpFddiPORTLemCts	1.3.6.1.2.1.10.15.4.2.1.17	Counter	read-only	The aggregate link error monitor error count, set to zero only on station power_up.
INT snmpFddiPORTLerCutoff	1.3.6.1.2.1.10.15.4.2.1.18	INTEGER	read-write	The link error rate estimate at which a link connection will be broken. It ranges from 10-4 to 10-15 and is reported as the absolute value of the exponent.
INT snmpFddiPORTLerAlarm	1.3.6.1.2.1.10.15.4.2.1.19	INTEGER	read-write	The link error rate estimate at which a link connection will generate an alarm. It ranges from 10-4 to 10-15 and is reported as the absolute value of the exponent of the estimate.
INT snmpFddiPORTConnectState	1.3.6.1.2.1.10.15.4.2.1.20	INTEGER	read-only	An indication of the connect state of this PORT. Basically, this gives a higher level view of the state of the connection by grouping PCM states and the PC-Withhold flag state. The supported values and their corresponding PCM states and PC-Withhold condition, when relevant, are: disabled: (PC0:Off, PC9:Maint) connecting: (PC1(Break) \|\| PC3 (Connect) \|\| PC4 (Next) \|\| PC5 (Signal) \|\| PC6 (Join) \|\| PC7 (Verify)) && (PC_Withhold = None) standby: (NOT PC_Withhold == None) active: (PC2:Trace \|\| PC8:Active)
INT snmpFddiPORTPCMState	1.3.6.1.2.1.10.15.4.2.1.21	INTEGER	read-only	(refer to SMT 9.6.2).
INT snmpFddiPORTPCWithhold	1.3.6.1.2.1.10.15.4.2.1.22	INTEGER	read-only	PC_Withhold, (refer to ANSI SMT 9.4.1).
INT snmpFddiPORTLerCondition	1.3.6.1.2.1.10.15.4.2.1.23	INTEGER	read-only	This variable is set to true whenever LerEstimate is less than or equal to LerAlarm.
OID snmpFddiPORTChipSet	1.3.6.1.2.1.10.15.4.2.1.24	OBJECT IDENTIFIER	read-only	This object identifies the hardware chip(s) which is (are) principally responsible for the implementation of the PORT (PHY) function. A few OBJECT IDENTIFIERS are identified elsewhere in this memo. For those The assignment of additional OBJECT IDENTIFIERs to various types of hardware chip sets is managed by the IANA. For example, vendors whose chip sets are not defined in this memo may request a number from the Internet Assigned Numbers Authority (IANA) which indicates the assignment of a enterprise specific subtree which, among other things, may be used to allocate OBJECT IDENTIFIER assignments for that enterprise's chip sets. Similarly, in the absence of an appropriately assigned OBJECT IDENTIFIER in this memo or in an enterprise specific subtree of a chip vendor, a board or system vendor can request a number for a subtree from the IANA and make an appropriate assignment. It is desired that, whenever possible, the same OBJECT IDENTIFIER be used for all chips of a given type. Consequently, the assignment made in this memo for a chip, if any, should be used in preference to any other assignment and the assignment made by the chip manufacturer, if any, should be used in preference to assignments made by users of those chips. If the hardware chip set is unknown, the object identifier unknownChipSet OBJECT IDENTIFIER ::= { 0 0 } is returned. Note that unknownChipSet is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.
INT snmpFddiPORTAction	1.3.6.1.2.1.10.15.4.2.1.25	INTEGER	read-write	This object, when read, always returns a value of other(1). The behavior of setting this variable to each of the acceptable values is as follows: Other: Results in a badValue error. maintPORT: Signal PC_Maint enablePORT: Signal PC_Enable disablePORT: Signal PC_Disable startPORT: Signal PC_Start stopPORT: Signal PC_Stop Signals cause an SM_CM_CONTROL.request service to be generated with a control_action of `Signal' and the `variable' parameter set with the appropriate value (i.e., PC_Maint, PC_Enable, PC_Disable, PC_Start, PC_Stop). Ref. ANSI SMT Section 9.3.2. Attempts to set this object to all other values results in a badValue error.
snmpFddiATTACHMENT	1.3.6.1.2.1.10.15.5
INT snmpFddiATTACHMENTNumber	1.3.6.1.2.1.10.15.5.1	INTEGER	read-only	The total number of attachments (across all SMTs) on this network management application entity. The value for this variable must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.
snmpFddiATTACHMENTTable	1.3.6.1.2.1.10.15.5.2		not-accessible	A list of ATTACHMENT entries. The number of entries is given by the value of snmpFddiATTACHMENTNumber.
snmpFddiATTACHMENTEntry	1.3.6.1.2.1.10.15.5.2.1		not-accessible	An ATTACHMENT entry containing information common to a given set of ATTACHMENTs. The ATTACHMENT Resource represents a PORT or a pair of PORTs plus the optional associated optical bypass that are managed as a functional unit. Because of its relationship to the PORT Objects, there is a natural association of ATTACHMENT Resource Indices to the PORT Indices. The resource index for the ATTACHMENT is equal to the associated PORT index for 'single-attachment' and 'concentrator' type snmpFddiATTACHMENTClasses. For 'dual-attachment' Classes, the ATTACHMENT Index is the PORT Index of the A PORT of the A/B PORT Pair that represents the ATTACHMENT.
INT snmpFddiATTACHMENTSMTIndex	1.3.6.1.2.1.10.15.5.2.1.1	INTEGER	read-only	The value of the SMT index associated with this ATTACHMENT.
INT snmpFddiATTACHMENTIndex	1.3.6.1.2.1.10.15.5.2.1.2	INTEGER	read-only	A unique value for each ATTACHMENT on a given SMT. Its value ranges between 1 and the sum of the values of snmpFddiSMTNonMasterCt { snmpFddiSMTEntry 6 } and snmpFddiSMTMasterCt { snmpFddiSMTEntry 7 } on the given SMT. The value for each ATTACHMENT must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.
INT snmpFddiATTACHMENTClass	1.3.6.1.2.1.10.15.5.2.1.3	INTEGER	read-only	The Attachment class. This represents a PORT or a pair of PORTs plus the associated optional optical bypass that are managed as a functional unit. The PORT associations are the following: single-attachment - S PORTs dual-attachment - A/B PORT Pairs concentrator - M PORTs
INT snmpFddiATTACHMENTOpticalBypassPresent	1.3.6.1.2.1.10.15.5.2.1.4	INTEGER	read-only	The value of this value is false for 'single- attachment' and { snmpFddiATTACHMENT 11 }. Correct operation of CMT for single-attachment and concentrator attachments requires that a bypass function must not loopback the network side of the MIC, but only the node side.
FDD snmpFddiATTACHMENTIMaxExpiration	1.3.6.1.2.1.10.15.5.2.1.5	FddiTime	read-only	I_Max (refer to ANSI SMT 9.4.4.2.1). It is recognized that some currently deployed systems do not implement an optical bypass. Systems which do not implement optical bypass should return a value of 0.
INT snmpFddiATTACHMENTInsertedStatus	1.3.6.1.2.1.10.15.5.2.1.6	INTEGER	read-only	Indicates whether the attachment is currently inserted in the node.
INT snmpFddiATTACHMENTInsertPolicy	1.3.6.1.2.1.10.15.5.2.1.7	INTEGER	read-write	Indicates the Insert Policy for this Attachment. Insert: True (1), Don't Insert: False (2), Unimplemented (3)
snmpFddiChipSets	1.3.6.1.2.1.10.15.6
snmpFddiPHYChipSets	1.3.6.1.2.1.10.15.6.1
snmpFddiMACChipSets	1.3.6.1.2.1.10.15.6.2
snmpFddiPHYMACChipSets	1.3.6.1.2.1.10.15.6.3
