Description: MICROSENS G6 switch MIB for Spanning Tree Protocol configuration and port/bridge state management.

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 G6-STP-MIB?

G6-STP-MIB is a MICROSENS private MIB for the Generation 6 switch family that configures Spanning Tree Protocol variants (STP/RSTP/MSTP) at the bridge level to prevent Layer 2 loops. It exposes bridge-wide configuration objects including STP mode, bridge priority, hello time, max age, forward delay, transmit hold count, the IEEE path cost model, and MSTP-specific region name and revision level. Its monitoring value is centered on network topology/configuration correctness, letting an admin confirm bridge parameters are consistent across a network to avoid topology instability, though it is configuration-state focused rather than reporting real-time port state changes or root bridge election results. No explicit dependency on other MIBs is indicated, though it parallels concepts from the standard BRIDGE-MIB and its RSTP/MSTP extensions. It is deployed on MICROSENS G6-series switches in Layer 2 networks using redundant links protected by spanning tree, where G6-STP-MIB SNMP monitoring helps confirm bridge parameters remain consistent across the topology.

IPNetwork Monitor allows you to monitor SNMP objects defined in G6-STP-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

MICROSENS G6-series Ethernet switch

Monitoring Examples

An admin diagnosing inconsistent spanning tree behavior across switches would compare bridgeConfigTable/bridgeConfigEntry values for bridgeConfigMode, bridgeConfigPriority, bridgeConfigHelloTime, and bridgeConfigMaxAge across devices to find a mismatched timer or priority causing unexpected root bridge changes. For an MSTP deployment, bridgeConfigMstpRegionName and bridgeConfigMstpRevisionLevel would be checked to confirm all switches agree on the same MST region, since a mismatch would incorrectly segment the network into separate regions.

What Can Be Monitored

STP/RSTP/MSTP mode
