What Is TIMETRA-BFD-MIB?

TIMETRA-BFD-MIB is a proprietary Alcatel-Lucent/Nokia SROS MIB (Timetra being the legacy internal name for the 7750 SR platform) used to configure and monitor Bidirectional Forwarding Detection (BFD), a protocol for rapid failure detection between routers. It exposes BFD template configuration (timers, multiplier, echo interval) and operational session-state objects reflecting the live status of BFD sessions on the router. It supports monitoring of protocol/software status rather than hardware; administrators use it to confirm that BFD templates are correctly applied and that sessions are up with the intended aggressive timers, since a misconfigured timer can materially delay failover detection. It builds on the general BFD concept standardized in IETF RFCs, though the object definitions themselves are Alcatel-Lucent/Nokia proprietary. It is typically deployed on Nokia 7750 SR and related SROS routers in service-provider networks where fast link/node failure detection is required for MPLS or routing protocol convergence. Engineers can download the TIMETRA-BFD-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-BFD-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.

Monitoring Examples

tmnxBfdAdminTemplateTable/Entry defines BFD templates with tmnxBfdAdminTemplateTxInt, tmnxBfdAdminTemplateRxInt, and tmnxBfdAdminTemplateMultiplier; an admin checks tmnxBfdAdminTemplateRowStatus to confirm a template is active and cross-references tmnxBfdOperObjects for the actual negotiated timers on a session. This reveals whether a critical link is really running with the intended aggressive BFD timers or has silently fallen back to slower defaults, which would delay failover detection.

What Can Be Monitored

tmnxBfdOperTemplateEntry	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1		not-accessible	Information about a particular BFD template. Entries are created by user via tmnxBfdAdminTemplateTable. Entries are deleted by user via tmnxBfdAdminTemplateTable.
TNA tmnxBfdOperTemplateName	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.1	TNamedItem	not-accessible	The name of this BFD template that uniquely identifies an entry in this table.
ROW tmnxBfdOperTemplateRowStatus	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.2	RowStatus	read-only	RowStatus for this row. Values read will only be active(1). To create or destroy entries in this table, use the tmnxBfdAdminTemplateEntry.
U32 tmnxBfdOperTemplateTxInt	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.3	Unsigned32	read-only	The value of tmnxBfdOperTemplateTxInt indicates the transmit timers for the BFD packets.
U32 tmnxBfdOperTemplateRxInt	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.4	Unsigned32	read-only	The value of tmnxBfdOperTemplateTxInt indicates the recieve timers for the BFD packets.
U32 tmnxBfdOperTemplateMultiplier	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.5	Unsigned32	read-only	The value of tmnxBfdOperTemplateMultiplier indicates the number of consecutive BFD messages that must be missed from the peer before the BFD session state is changed to down and the upper level protocols (OSPF, IS-IS or PIM) are notified of the fault.
U32 tmnxBfdOperTemplateEchoRxInt	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.6	Unsigned32	read-only	The value of tmnxBfdOperTemplateEchoRxInt indicates the minimum echo recieve interval for a BFD session.
INT tmnxBfdOperTemplateType	1.3.6.1.4.1.6527.3.1.2.85.1.1.1.1.7	INTEGER	read-only	The value of tmnxBfdOperTemplateType indicates the configured termination of a BFD session. The value of 'cpmNp(1)' specifies termination on the CPM card's Network Processor. The value of 'auto(2)' specifies a system-selected termination other than the CPM Network Processor.
tmnxBfdAdminObjects	1.3.6.1.4.1.6527.3.1.2.85.2
tmnxBfdAdminControlObjects	1.3.6.1.4.1.6527.3.1.2.85.2.1
STR tmnxBfdAdminOwner	1.3.6.1.4.1.6527.3.1.2.85.2.1.1	DisplayString	read-write	Who has last initialized the administrative tables, who is making all the changes, and who is expected to either commit or re-initialize (ABORT-TRANSACTION). tmnxBfdAdminOwner is advisory only. Before beginning a transaction, read tmnxBfdAdminOwner. If it is empty then proceed with the configuration. Set tmnxBfdAdminOwner after setting tmnxBfdAdminControlApply so that other users will be advised to not make changes to the Admin tables. Agent sets tmnxBfdAdminOwner to empty string after tmnxBfdAdminControlApply is set - either by user initializing or committing, or by agent timing out the uncommitted transactions (tmnxBfdAdminLastSetTimer).
INT tmnxBfdAdminControlApply	1.3.6.1.4.1.6527.3.1.2.85.2.1.2	INTEGER	read-write	This object controls the use of tmnxBfdAdminValueObjects tables. This object always reads none(1). When set to initialize(2), the objects in tmnxBfdAdminValueObjects tables are set to the current Operational values, from the corresponding tmnxBfdOperValueObjects tables. Any uncommitted changes are lost, so setting this value corresponds to both BEGIN-TRANSACTION and ABORT-TRANSACTION. When set to commit(3) (END-TRANSACTION), all of the objects from tmnxBfdAdminValueObjects tables are copied to the corresponding tmnxBfdOperValueObjects table objects.
NUM tmnxBfdAdminLastSetTimer	1.3.6.1.4.1.6527.3.1.2.85.2.1.3	TimeInterval	read-only	The time remaining until the agent re-initializes the administrative tables. If tmnxBfdAdminControlApply is not set to commit(3) within tmnxBfdAdminLastSetTimeout centiseconds, the agent will set it to initialize(2) and all uncommitted changes will be lost. This way, uncommitted changes from failed (uncompleted) change sets will eventually be removed, and another transaction can safely begin. This object is reset to tmnxBfdAdminLastSetTimeout after SNMP SET operation to any of the tmnxBfdAdminValueObjects tables.
NUM tmnxBfdAdminLastSetTimeout	1.3.6.1.4.1.6527.3.1.2.85.2.1.4	TimeInterval	read-write	Timeout for tmnxBfdAdminLastSetTimer. The value zero is not allowed.
tmnxBfdAdminValueObjects	1.3.6.1.4.1.6527.3.1.2.85.2.2
tmnxBfdAdminTemplateTable	1.3.6.1.4.1.6527.3.1.2.85.2.2.1		not-accessible	Administrative value table for BFD templates.
tmnxBfdAdminTemplateEntry	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1		not-accessible	Information about a particular BFD template. Entries are created by user. Entries are deleted by user.
TNA tmnxBfdAdminTemplateName	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.1	TNamedItem	not-accessible	The name of this BFD template that uniquely identifies an entry in this table.
ROW tmnxBfdAdminTemplateRowStatus	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.2	RowStatus	read-create	RowStatus for this row. Legal values to write are: active(1), createAndGo(4), createAndWait(5), destroy(6). To Create a row, set this object to createAndGo or createAndWait. When tmnxBfdAdminControlApply is set to commit(3), the row will actually be created in the tmnxBfdOperTemplateTable. To destroy a row, set this object to destroy(6). If there are no objects that refer to the entry, when tmnxBfdAdminControlApply is set to commit(3) the row will actually be removed from the tmnxBfdOperTemplateTable. If there are objects that refer to the entry, the destroy SET request will fail with an error.
U32 tmnxBfdAdminTemplateTxInt	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.3	Unsigned32	read-create	The value of tmnxBfdAdminTemplateTxInt specifies the transmit timers for the BFD packets.
U32 tmnxBfdAdminTemplateRxInt	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.4	Unsigned32	read-create	The value of tmnxBfdAdminTemplateRxInt specifies the receive timers for the BFD packets.
U32 tmnxBfdAdminTemplateMultiplier	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.5	Unsigned32	read-create	The value of tmnxBfdAdminTemplateMultiplier specifies the number of consecutive BFD messages that must be missed from the peer before the BFD session state is changed to down and the upper level protocols (OSPF, IS-IS or PIM) are notified of the fault.
U32 tmnxBfdAdminTemplateEchoRxInt	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.6	Unsigned32	read-create	The value of tmnxBfdAdminTemplateEchoRxInt specifies the minimum echo recieve interval for a BFD session.
INT tmnxBfdAdminTemplateType	1.3.6.1.4.1.6527.3.1.2.85.2.2.1.1.7	INTEGER	read-create	The value of tmnxBfdAdminTemplateType specifies the configured termination of a BFD session. The value of 'cpmNp(1)' specifies termination on the CPM card's Network Processor. The value of 'auto(2)' specifies a system-selected termination other than the CPM Network Processor.
