What Is APPIAN-LPORT-PPP-MIB?

APPIAN-LPORT-PPP-MIB is a vendor-specific MIB from Appian Communications covering PPP and Multilink PPP (MLPPP) services on logical ports of Appian's access/transport platforms. It exposes configuration and status data for individual PPP links, including negotiated link parameters, compression settings, and control-map values exchanged during LCP/NCP negotiation. Its primary monitoring value is software/protocol status rather than physical hardware: acPppLinkStatusLocalMRU/RemoteMRU reveal whether the negotiated maximum receive units match expectations, and the ACC-map and compression-mode objects (acPppLinkStatusLocalToRemoteProtocolCompression, acPppLinkStatusLocalToRemoteACCompression) show whether link-layer optimizations successfully negotiated between peers. It depends on the identification scheme of the underlying Appian node/slot/timeslot addressing (acPppLinkStatusNodeId, acPppLinkStatusTimeSlotIndex) used across the Appian MIB family. It is deployed on Appian OSAP access-transport platforms used by carriers for PPP-based leased-line or TDM-to-packet aggregation services. Network engineers evaluating or troubleshooting this functionality can download the APPIAN-LPORT-PPP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in APPIAN-LPORT-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.

Monitoring Examples

An administrator polling acPppLinkStatusTable would key on acPppLinkStatusNodeId and acPppLinkStatusTimeSlotIndex to locate a specific logical PPP link, then compare acPppLinkStatusLocalMRU to acPppLinkStatusRemoteMRU to confirm both ends negotiated a compatible MRU. A mismatch or unexpectedly small negotiated compression state in acPppLinkStatusLocalToRemoteProtocolCompression versus acPppLinkStatusRemoteToLocalProtocolCompression would indicate an LCP renegotiation problem degrading link efficiency. Monitoring acPppLinkStatusPeerToLocalACCMap alongside acPppLinkStatusLocalToPeerACCMap helps catch async-control-character-map mismatches that can corrupt PPP framing.

What Can Be Monitored

negotiated local/remote MRU
protocol compression negotiation state
AC compression negotiation state
ACC map values
PPP link identification (node/timeslot)
