What Is USR-PPPLINK-MIB?
USR-PPPLINK-MIB is a proprietary CommWorks/3Com (US Robotics) MIB for managing PPP (Point-to-Point Protocol) link parameters and LCP (Link Control Protocol) negotiation on their broadband/remote-access equipment. No sample objects were available from the source, but such a module would typically expose per-link PPP/LCP negotiated options (MRU, authentication type, magic number), link status, and negotiation counters or failure indications. Its monitoring focus would be software/protocol status of PPP links — whether LCP negotiation completed successfully and the link is up and stable — rather than physical hardware health, complementing the standard PPP MIB (RFC 1471) it likely parallels or extends. It would be deployed on 3Com/CommWorks dial-up or leased-line remote-access concentrators terminating PPP sessions. Engineers can download the USR-PPPLINK-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in USR-PPPLINK-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 status
- LCP negotiation state
- negotiated link parameters
- link negotiation failure indications
Supported Devices
- CommWorks/3Com (US Robotics) PPP-terminating access equipment
Monitoring Examples
No sample objects were provided for this MIB, so a concrete object-level monitoring scenario cannot be honestly described; typically an admin would expect to poll per-link LCP negotiation state and status to confirm PPP sessions are established correctly, but the exact object names cannot be confirmed here.
