Description: Manages Frame Relay interface configuration on ACC/Ericsson routers, including DLCI management, LMI protocol settings, and traffic statistics.

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 ACC-FR?

ACC-FR is a vendor-specific MIB for managing Frame Relay interfaces on ACC/Ericsson access routers, covering DLCI (Data Link Connection Identifier) configuration, LMI (Local Management Interface) protocol settings, and per-DLCI traffic statistics. It provides configuration data such as DLCI numbers and LMI type/polling settings, alongside performance/fault statistics such as frames and bytes sent/received and DLCI status changes. Its monitoring value is squarely on WAN link/software health, since LMI status reveals whether the router's Frame Relay software has an active management link with the carrier switch, and per-DLCI status/statistics reveal whether an individual virtual circuit is up, congested, or experiencing errors. It follows general Frame Relay standards (ANSI T1.617/ITU Q.933 LMI) implemented as a proprietary counters module. It is deployed on ACC/Ericsson WAN access routers connecting to a carrier's Frame Relay network for branch-office connectivity, monitored via the ACC-FR MIB objects described above.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACC-FR. 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.

ACC/Ericsson WAN access router (Frame Relay)

Monitoring Examples

An admin polls per-DLCI status to confirm all provisioned Frame Relay circuits are active, and reviews LMI status/type to verify the router still has a healthy management link to the carrier's Frame Relay switch. A DLCI reporting inactive while LMI is up would point to a carrier-side provisioning issue rather than a local router or cabling fault, while accumulating frame errors on a specific DLCI would suggest a congested or degraded circuit.

What Can Be Monitored

DLCI status (active/inactive)
LMI protocol status/type
per-DLCI frame/byte traffic statistics
Frame Relay circuit errors
