Description: Handles bridging configuration for LANBuilder network hub modules.

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 LBHUB-BRIDGE-MIB?

LBHUB-BRIDGE-MIB is a legacy 3Com (enterprise OID 43, LinkBuilder hub bridge module) proprietary MIB reporting bridge-port traffic and forwarding-database statistics. Its objects cover a clear-counters action, STA-protocol/learn/aging mode flags, a per-port monitor table (percent traffic forwarded, bandwidth used, errors per 10,000 packets, broadcast bandwidth), filtering-database size and percentage breakdown (non-aging/aging/permanent entries), a clear-filtering-database action, max permanent entries, percentage of permanent database used, a clear-permanent-entries action, a save-learnt-addresses action, database-modified flag, database type/level, and traffic-forwarded count. As a performance/status MIB it lets an administrator watch per-port bridge traffic and forwarding-database utilization on a legacy 3Com LinkBuilder hub. It is deployed on legacy 3Com LinkBuilder hub/bridge equipment. Engineers can download the LBHUB-BRIDGE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LBHUB-BRIDGE-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
