Description: MICROSENS G6 switch MIB for physical port configuration including speed, duplex, and operational state.

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-PORT-MIB?

G6-PORT-MIB is a MICROSENS private MIB for Generation 6 Ethernet switches covering the physical configuration of each switch port, including speed, duplex, MTU, flow control, auto-negotiation, and loop protection. It exposes a per-port configuration table keyed by port index with an alias, operational role, and these link-layer settings. This is chiefly a hardware/link-configuration status MIB: an operator can confirm whether a port is up, correctly negotiated, and protected against switching loops, all fundamental physical-layer health indicators for an Ethernet switch. As a vendor-private port MIB it likely parallels standard IF-MIB/EtherLike-MIB concepts but is not explicitly stated to depend on them. It is deployed on every MICROSENS G6 switch for day-to-day port-level configuration and health monitoring. Network engineers evaluating or troubleshooting this functionality can download the G6-PORT-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

An administrator would poll configSpeed, configFullDuplex, and configAutoNegotiation in configTable for a given configPortIndex to confirm a link partner negotiated the expected speed/duplex, catching classic duplex-mismatch problems. configLoopProtection would be checked after a suspected bridging loop event to confirm loop-guard was enabled on the affected port, and configFlowcontrol would be checked when troubleshooting congestion-related drops. configAlias and configRole help identify the port's intended purpose during triage.

I32 monitorDestination	1.3.6.1.4.1.3181.10.6.1.81.2.1.4	Integer32	read-write	Port on which the traffic monitored on the source port shall be copied to. Normally a network sniffer is connected to this port. Please observe that possibly the VLAN setting of the destination port must match the that of the monitored ports. CLI Syntax: 1/1 for first port.
STR portRestartPort	1.3.6.1.4.1.3181.10.6.1.81.3	DisplayString	read-write	This function may be used to briefly disabled and enable the port.
