Description: Manages miscellaneous IP protocol settings on ACC/Ericsson routers including proxy-ARP, directed broadcast handling, and ICMP rate limiting.

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-IPMISC?

ACC-IPMISC is an ACC/Ericsson (ACC was acquired by Ericsson) enterprise MIB covering miscellaneous IP-layer protocol settings on ACC routers, including proxy-ARP behavior, handling of directed (subnet) broadcast packets, and ICMP rate limiting. Its data is primarily configuration-oriented, controlling how the router's IP stack behaves for these specific protocol features rather than exposing traffic-volume statistics. As a monitoring tool it would be used to confirm these IP-layer protections and behaviors are configured as intended, verifying proxy-ARP is enabled/disabled per the network design, that directed broadcast forwarding is appropriately restricted (a common security hardening measure), and that ICMP rate limiting thresholds are in place to protect the router's control plane from being overwhelmed. No dependency on other MIBs is apparent from the available data, consistent with it being a small, self-contained configuration MIB. It is typically deployed on ACC/Ericsson routers in service-provider or enterprise WAN edge deployments. Engineers can download the ACC-IPMISC file directly to load it into their MIB browser.

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

No sample objects were provided for this module; based on its stated purpose, a typical check would involve confirming the configured state of proxy-ARP, directed-broadcast forwarding, and ICMP rate-limiting thresholds, where directed broadcast being unexpectedly enabled would flag a security misconfiguration exposing the router to smurf-style amplification attacks.

What Can Be Monitored

proxy-ARP enable state
directed broadcast forwarding setting
ICMP rate-limit configuration
