Description: MAC address table management for Ubiquoss EPON OLT PON ports, including per-ONU MAC address and administrative status

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 UBIQUOSS-EPON-PON-MAC-GROUP-MIB?

UBIQUOSS-EPON-PON-MAC-GROUP-MIB is a private MIB from Ubiquoss, a maker of EPON (Ethernet Passive Optical Network) access equipment, for managing MAC address learning and forwarding on the PON ports of an EPON OLT (Optical Line Terminal), including per-ONU MAC address entries and their administrative status. Its data is squarely about access-layer software state -- which MAC addresses have been learned on which PON port/ONU, and whether that binding is administratively enabled or disabled -- used for subscriber and security management. Its monitoring value lies in confirming subscriber-facing software status: verifying that an ONU's MAC address is correctly learned and active, or spotting a MAC learning table growing beyond expected size (a possible MAC-flooding or misconfigured bridge condition) rather than reporting on optical hardware directly. It builds on standard bridge/MAC-address-table conventions (BRIDGE-MIB style indexing) adapted per PON port. It is deployed on Ubiquoss EPON OLT chassis in FTTH access networks to manage and troubleshoot per-subscriber MAC bindings. Engineers can download the UBIQUOSS-EPON-PON-MAC-GROUP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in UBIQUOSS-EPON-PON-MAC-GROUP-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.

Supported Devices

  • Ubiquoss EPON OLT (Optical Line Terminal) access equipment

Monitoring Examples

No specific object names were provided in this excerpt (sample_objects is empty), but consistent with its description an administrator would poll a per-PON-port MAC address table to confirm a given ONU's MAC address is present and administratively enabled, and would watch for an unexpectedly large number of learned MAC entries on one PON port, which could indicate a rogue device or a MAC-flooding condition on that ONU's segment.

What Can Be Monitored

  • per-ONU learned MAC addresses
  • MAC address administrative status
  • MAC entries per PON port
  • MAC table size/growth per port
