Category: IP and Core Protocols, Vendor: ACC/Ericsson
Description: Manages ARP (Address Resolution Protocol) configuration and proxy ARP settings on ACC/Ericsson routers, including ARP table management and timeout values.
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-ARP?
ACC-ARP is a vendor-specific MIB from ACC (later acquired by Ericsson) for managing Address Resolution Protocol behavior on ACC access/dial routers, including ARP table entries, proxy ARP enablement, and ARP entry timeout values. It is a configuration and small-state MIB rather than a large counters MIB, exposing per-interface ARP settings and the resulting resolved address mappings. Its monitoring value is in confirming correct Layer 2/3 address resolution behavior on the router, since checking whether proxy ARP is enabled where expected and whether ARP entries are aging out and being refreshed correctly helps diagnose connectivity problems caused by stale or missing ARP mappings. It relies on the base IETF concepts of the standard ARP mechanism, similar in spirit to the ipNetToMedia table, though implemented as a proprietary ACC module. It is typically deployed on ACC/Ericsson dial-up and ISDN access routers used by service providers for remote-access network termination, making ACC-ARP SNMP monitoring a standard part of address-resolution troubleshooting on these platforms.
IPNetwork Monitor allows you to monitor SNMP objects defined in ACC-ARP. 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.
Supported Devices
- ACC/Ericsson dial-up or ISDN access router
Monitoring Examples
An admin would poll the router's ARP table entries and the proxy-ARP enable flag for a given interface to confirm a remote dial-in client's address is resolving correctly. A missing or stale ARP entry combined with an unexpectedly short configured timeout value would explain intermittent connectivity reports from that client's subnet.
What Can Be Monitored
- ARP table entries/mappings
- proxy ARP enable state
- ARP entry timeout configuration
