Description: IEEE 802.1 bridge management for Ubiquoss Ethernet switches, covering VLAN membership, STP/RSTP/MSTP state, and bridge port configuration

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 UBQS-DOT1BRIDGE-MIB?

UBQS-DOT1BRIDGE-MIB is a vendor-specific MIB from Ubiquoss implementing IEEE 802.1 bridge management for its Ethernet switch product line, covering VLAN membership, MAC address table management, and spanning-tree (STP/RSTP/MSTP) protocol state. It exposes object groups for VLAN configuration (ubiVlanMIBObjects), bridge configuration (ubiBridgeMIBObjects), and the switch's learned MAC address table (ubiMacAddressTableMIBObjects), along with notification support for VLAN-related events. This MIB is primarily a Layer-2 configuration and status MIB, letting an operator monitor the software-level state of bridging, VLAN membership, spanning-tree port states, and MAC table contents, to detect misconfigured VLANs, spanning-tree topology changes, or MAC table anomalies such as flapping or exhaustion. As its name indicates, it is explicitly built as a private-enterprise implementation of the IEEE 802.1 standard, layering vendor-specific object groups over the concepts of the standard BRIDGE-MIB/Q-BRIDGE-MIB. It is typically deployed on Ubiquoss access/aggregation Ethernet switches in carrier or enterprise networks. Engineers can download the UBQS-DOT1BRIDGE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in UBQS-DOT1BRIDGE-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.

Ubiquoss Ethernet switch

Monitoring Examples

An operator would poll objects under ubiVlanMIBObjects to confirm VLAN membership assignments match the intended configuration, and use ubiVlanNotifications traps to detect unauthorized or unexpected VLAN changes. ubiMacAddressTableMIBObjects would be polled to check the switch's learned MAC address table for size or for a specific MAC's port binding, revealing a loop or MAC-flapping condition if entries change rapidly. ubiBridgeMIBObjects exposes general bridge/STP configuration state useful for confirming spanning-tree is active on the expected ports.
