What Is LB3GH-1-0-7?

LB3GH-1-0-7 is a legacy 3Com enterprise MIB (RFC1155-SMI/RFC-1212 macro style, under the a3Com enterprise OID) for the LinkBuilder 3GH modular hub chassis. Despite the batch's hint describing it as a load-balancer, the module's actual object tree — chassis, slot, smm, fbcm/fcm card groups, FDDI concentrator MAC/port groups, Ethernet port groups, and a bridging group — shows it manages a multi-slot Ethernet/FDDI hub with integral transparent bridging, not load-balancing. It exposes chassis/slot board inventory and status (slotBoardType, slotBoardStatus), FDDI MAC and Ethernet port statistics, a redundant power-supply group (lbPowerSupply), and a bridging group (lbBridgeTable/lbBridgePortTable) tracking per-bridge-port forwarded-frame counts, discards, and address-table thresholds, alongside numerous legacy TRAP-TYPE notifications for board, power-supply, and bridge-address-threshold events. It's useful for tracking the health of the hub's slot cards, power supplies, and bridging address table on an aging 3Com LinkBuilder 3GH chassis, and administrators can download the LB3GH-1-0-7 file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LB3GH-1-0-7. 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

  • 3Com LinkBuilder 3GH modular hub/FDDI concentrator chassis

Monitoring Examples

An operator polls slotBoardStatus for each slotIndex in slotTable to confirm all installed cards report normal, and watches lbBridgePortTotalDiscards alongside lbBridgeAddressThreshold in lbBridgeTable/lbBridgePortTable; discards climbing as the address table nears its threshold would indicate the bridge's MAC table is full and dropping frames.

What Can Be Monitored

  • chassis/slot board type & status
  • power supply status
  • FDDI MAC & port statistics
  • Ethernet port statistics
  • bridge port forwarded-frame & discard counters
  • bridge address-table threshold events
