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.
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
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.

| 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. | |
| tmnxPppEntry | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1 | not-accessible | Each row entry represents a port from the tmnxPortTable that is configured for PPP. Entries cannot be created and deleted via SNMP SET operations. | |
| 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. |
| IP tmnxPppRemoteAddress | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.3 | IpAddress | read-only | The Ip address of the remote end of the PPP link. This object was made obsolete in the 4.0 release. |
| MAC tmnxPppRemoteMacAddress | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.4 | MacAddress | read-only | The Ethernet MacAddress sent by the remote end of the PPP link. |
| 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. |
| U32 tmnxPppKaPeriod | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.6 | Unsigned32 | read-write | The value tmnxPppKaPeriod is used to configure the time interval in seconds at which keepalive requests are issued. When LQM is enabled by setting tmnxPppQuality equal to some value other than zero (0), keepalives are replaced with LQR messages. |
| U32 tmnxPppKaDropCount | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.7 | Unsigned32 | read-write | The value of tmnxPppKaDropCount determines how many keepalive or LQR messages can be missed before the line is brought down. |
| TIM tmnxPppKaLastClearedTime | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.8 | TimeStamp | read-only | The last time that keepalive stats were cleared. Note that the keepalive stats are cleared when changing from LQM to keepalives or vice versa. |
| 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. |

| 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 tmnxPppLqmOperPeriod | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.14 | Unsigned32 | read-only | The value tmnxPppLqmOperPeriod is the negotiated time interval in seconds at which LQM LQR requests are issued. |
| G32 tmnxPppLqmInRate | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.15 | Gauge32 | read-only | The average of 'SaveInPackets'/'PeerOutPackets' in the last five consecutive LQRs received. |
| G32 tmnxPppLqmOutRate | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.16 | Gauge32 | read-only | The average of 'PeerInPackets'/'LastOutPackets' in the last five consecutive LQRs received. |

| C32 tmnxPppLqmInPktCount | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.19 | Counter32 | read-only | The number of LQR packets received. |
| C32 tmnxPppLqmOutPktCount | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.20 | Counter32 | read-only | The number of LQR packets sent. |
| NUM tmnxPppLqmTimeDropLink | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.21 | TimeInterval | read-only | The time remaining before the link will be declared dropped if a LQM LQR message packet is not received. |
| U32 tmnxPppLocalMagicNumber | 1.3.6.1.4.1.6527.3.1.2.2.5.1.1.22 | Unsigned32 | read-only | tmnxPppLocalMagicNumber is the local magic number to be sent to the peer. 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. |
| 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. |

| tmnxPppCpEntry | 1.3.6.1.4.1.6527.3.1.2.2.5.2.1 | not-accessible | Each row entry represents a specific Ppp Control Protocol being run on a specific port from the tmnxPortTable that is configured for PPP. Entries cannot be created and deleted via SNMP SET operations; rows are created and deleted by the agent as the tmnxPortClass and tmnxPortEncapType values are modified. For any specific link, there is one Link Control Protocol (LCP) plus one or more Network Control Protocols (NCP) depending on the type of protocols supported on the link: ipcp, mplscp, bcp or osicp. | |
