Description: Manages Nokia/Alcatel-Lucent 7750 SR PPP link configuration, LCP parameters, and session state.

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 TIMETRA-PPP-MIB?

TIMETRA-PPP-MIB is a Nokia/Alcatel-Lucent 7750 SR (Timetra/SROS) proprietary MIB that manages Point-to-Point Protocol link configuration, LCP (Link Control Protocol) negotiation parameters, and PPP session state on service router hardware. It exposes a mix of configuration data (link phase, local/remote addressing) and operational/performance counters such as keepalive intervals, dropped-keepalive counts, and threshold-exceeded counts for PPP sessions. Its monitoring value centers on software/link status: tmnxPppLinkPhase reveals whether a PPP link is up, negotiating, or terminating, while the keepalive counters (tmnxPppKaDropCount, tmnxPppKaThresholdExceedsCount) reveal degrading link health before a full outage occurs, making this MIB valuable for proactive PPP session fault detection. It is part of the broader TIMETRA/SROS MIB family, and the TIMETRA-PPP-MIB OID tree depends on standard IF-MIB interface indexing conventions to correlate PPP sessions with physical/logical interfaces. It is deployed on Alcatel-Lucent (Nokia) 7750 SR and related SROS-based service router platforms running PPP encapsulation over WAN or access links.

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

Nokia/Alcatel-Lucent 7750 SR and related SROS-based service router platforms, entire product line (PPP link/LCP negotiation status)

Monitoring Examples

An administrator would poll tmnxPppTable/tmnxPppEntry, keyed to an interface, to check tmnxPppLinkPhase and tmnxPppRemoteAddress for the negotiated PPP peer, and would watch tmnxPppKaDropCount and tmnxPppKaThresholdExceedsCount to catch keepalive failures. A rising tmnxPppKaDropCount alongside tmnxPppKaLastClearedTime showing no recent reset would reveal an unstable PPP link that is dropping keepalives and at risk of going down. tmnxPppLineMonitorMethod and tmnxPppKaPeriod would be checked to confirm the monitoring method and interval configured for that link.

What Can Be Monitored

PPP link phase/state
negotiated local and remote addresses
keepalive drop count
keepalive threshold exceeded count
keepalive period and last-cleared time

When LQM is enabled by setting tmnxPppQuality equal to some value other than zero (0), keepalives are replaced with LQR messages.
C32 tmnxPppKaThresholdExceedsCount	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.9	Counter32	read-only	The number of times that tmnxPppKaDropCount was reached.

NTF tmnxPppKeepaliveFailure	1.3.6.1.4.1.6527.3.1.3.2.3.0.5			Generated when the keepalive based on echo packets failed.
INT tmnxPppLineMonitorMethod	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.5	INTEGER	read-only	The type of line monitoring packets being sent and received on this PPP link. Note that this can be deduced from the values of tmnxPppKaPeriod and tmnxPppQuality. One can find out whether lqm or keepalive is enabled or not. That is, lqm is enabled (keepalive is disabled) if tmnxPppQuality is not zero; and keepalive is enabled if tmnxPppKaPeriod is not zero and tmnxPppQuality is zero. If tmnxPppQuality and tmnxPppKaPeriod are both set to zero, no line monitoring is used.
INT tmnxPppLinkPhase	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.1	INTEGER	read-only	The current link phase for this PPP connection.
IP tmnxPppLocalAddress	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.2	IpAddress	read-only	The Ip address assigned the local end of the PPP link. This object was made obsolete in the 4.0 release.

The magic number provides a method to detect loopbacks. If the value of tmnxPppLocalMagicNumber is the same as the value of tmnxPppRemoteMagicNumber, then it is possible that the link might be looped back. If the two magic numbers do not match, then the link is not looped back.

NTF tmnxPppLqmFailure	1.3.6.1.4.1.6527.3.1.3.2.3.0.6			Generated when the link has failed in meeting the specified quality percentage.

tmnxPPPObsoleteV4v0Group	1.3.6.1.4.1.6527.3.1.1.2.3.2.4			The group of objects in TIMETRA-PPP-MIB which are obsoleted.
U32 tmnxPppQuality	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.13	Unsigned32	read-write	The value of tmnxPppQuality is a percentage used by LQM to monitor the link quality. If the quality drops below this percentage, the router shuts down the link. The percentages are calculated for both the incoming and outgoing directions. When LQM is enabled by setting tmnxPppQuality to a non-zero value, Link Quality Reports (LQRs) are sent, in place of keepalives, every keepalive period. All incoming keepalives and/or LQRs are always responded to regardless of the setting of tmnxPppQuality. A value of zero (0) implies no LQM quality monitoring and is the only value supported.

U32 tmnxPppRemoteMagicNumber	1.3.6.1.4.1.6527.3.1.2.2.5.1.1.23	Unsigned32	read-only	tmnxPppRemoteMagicNumber is the magic number sent by the peer. If the value of tmnxPppRemoteMagicNumber is the same as the value of tmnxPppLocalMagicNumber, then it is possible that the link might be looped back. If the two magic numbers do not match, then the link is not looped back.
tmnxPppTable	1.3.6.1.4.1.6527.3.1.2.2.5.1		not-accessible	The tmnxPppTable has an entry for each port in the system that is configured for PPP.
