ANS-COMMON-MIB

Description: ANS CO+RE common MIB definitions and shared objects for network service management.

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.

ANS-COMMON-MIB is a shared/common MIB module from Ericsson's ANS CO+RE (mobile packet core, referencing the mlpmp/mlpmpR115 product branch) network service management suite, defining objects reused across multiple Ericsson ANS MIBs. Its notable content is an error message table that captures reported error conditions with a request identifier and error code, providing a generic mechanism for surfacing fault/error status from the underlying system. Its monitoring value is therefore centered on fault reporting: polling for new entries or specific codes in the error message table reveals software or processing errors occurring on the platform, complementing more specific ANS MIBs' operational counters. Because it is a shared building block, ANS-COMMON-MIB SNMP polling is rarely done in isolation; it accompanies queries into the more specific ANS/mlpmp MIBs it supports, and it depends on the Ericsson enterprise OID structure (ericsson, mlpmp branches) as a common building block imported by those other MIBs. It is deployed in Ericsson mobile packet core (ANS CO+RE) network elements used by mobile operators.

An operator would poll errorMessageTable/errorMessageEntry, keyed by errorMessageRequestId, to retrieve errorMessageCode for a given failed request, helping correlate a specific operation failure with an internal error code for troubleshooting. Because this is a common/shared MIB, this error table would typically be referenced from other Ericsson ANS/mlpmp MIBs when a request into those subsystems fails, giving a centralized place to check for outstanding or historical error conditions. A growing or non-empty errorMessageTable would signal a processing problem on the ANS CO+RE element that needs investigation.
