Description: Manages BATM Advanced Communication ring-based Ethernet Protection Switching combining ring topology with EPS linear protection.

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 PRVT-RING-EPS-MIB?

PRVT-RING-EPS-MIB is a BATM Advanced Communication proprietary MIB (built on PRVT-SWITCH-MIB) implementing ITU-T G.8032 Ring Ethernet Protection Switching. Its instance table, keyed by index, records mode, node role, ring state, a local manual command, control VLAN, port-0/port-1 ifIndex, RPL (Ring Protection Link) port, manual-switch port, CFM maintenance-domain level, port-0/port-1 MEP, revertive flag, no-virtual-channel flag, hold-off/wait-to-restore/guard/wait-to-block timers, defect-FOP (Failure of Protocol) flag, port-0/port-1 status, and peer node ID. As a configuration/status MIB it lets an administrator confirm ring topology, RPL assignment, and protection-switching state on a BATM G.8032 ring device. It is deployed on BATM Advanced Communication equipment (G.8032 Ring Ethernet Protection Switching). Engineers can download the PRVT-RING-EPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PRVT-RING-EPS-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.

NTF prvtRingEpsDefectAlarm	1.3.6.1.4.1.738.1.5.134.0.1			This trap will be sent by any instance when it notices a defect. So far only the situation when two or more RPL-owners are defined in the ring is identified as a defect.
