Description: Manages RPM (Route Processor Module) connection configuration on Cisco MGX 8200 WAN switching platforms.

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 CISCO-MGX82XX-RPM-CONN-MIB?

CISCO-MGX82XX-RPM-CONN-MIB is a Cisco-specific module for the MGX 8230/8250 WAN switching platforms, managing connections (channels) associated with the Route Processor Module (RPM) service blade. It exposes configuration data describing ATM-style connection endpoints — slot, interface, channel number, VPI/VCI, sub-interface, and local VPI/VCI mappings — along with row-status controls for provisioning. Its role is primarily configuration/provisioning oriented rather than deep hardware health monitoring, though row status and connection presence can be used to confirm that expected RPM channels are correctly established and operational. It builds on general Cisco WAN switching connection-management conventions used across the MGX product family. It is typically deployed by carriers and enterprises using MGX 8230/8250 chassis with RPM route processor blades for multiservice ATM/Frame Relay/IP WAN aggregation. Engineers can download the CISCO-MGX82XX-RPM-CONN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MGX82XX-RPM-CONN-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 would walk rpmChanGrpTable/rpmChanGrpEntry to enumerate configured channels by rpmChanSlotNum, rpmChanInterface, and rpmChanNum, and inspect rpmChanVpi/rpmChanVci alongside rpmChanLocalVpi/rpmChanLocalVci to verify that a connection's local and remote virtual path/channel identifiers match the provisioned service. Checking rpmChanRowStatus reveals whether a channel entry is active, not-in-service, or in an error state, which helps diagnose a connection that fails to pass traffic. rpmChanSubInterface further narrows monitoring to a specific sub-interface segment of a channel.

What Can Be Monitored

RPM channel configuration by slot/interface/channel number
VPI/VCI and local VPI/VCI mapping
sub-interface assignment
channel row/connection status
