Description: MICROSENS G6 switch MIB for MAC address table management, aging, and static entry 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 G6-MAC-MIB?

G6-MAC-MIB is a MICROSENS private MIB for the company's Generation 6 (G6) Ethernet switch line, covering Layer 2 MAC address table management including filtering, aging, and static/multicast entry configuration. It exposes objects for per-port and per-VLAN MAC filtering, multicast MAC-to-VLAN/port mapping, MAC table clearing actions, and global aging timer and entry-count settings. While primarily a configuration MIB, macNumberOfEntries and the table-clear actions give administrators visibility into MAC table utilization, letting them react to table-full conditions or stale/incorrect entries, effectively a software-state monitoring role for the switch's forwarding database. It is a standalone vendor-private MIB without notable dependency on standard bridge MIBs beyond general SNMP conventions. It is deployed on MICROSENS G6-series managed Ethernet switches in industrial or building network environments, typically managed via a G6-MAC-MIB MIB Browser for direct inspection of these objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in G6-MAC-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 managed Ethernet switch

Monitoring Examples

An admin can poll macNumberOfEntries to track how full the MAC address table is, alerting if it approaches switch capacity limits. Reviewing macFilterPort/macFilterMac entries alongside macGlobalAgingTime helps diagnose why a device's traffic is being blocked or why stale MAC entries are lingering, and macClearLearnedMacTable/macClearMacTableForVlan can be invoked to force a MAC table flush during troubleshooting.

What Can Be Monitored

MAC address table entry count
MAC filter rules per port/VLAN
MAC aging time
multicast MAC-to-VLAN mapping

OID symbolic	OID numeric	Type	Access	Description
device	1.3.6.1.4.1.3181.10.6.1			Microsens private MIB for Generation 6 Ethernet Switches
mac	1.3.6.1.4.1.3181.10.6.1.86
STR macFilterPort	1.3.6.1.4.1.3181.10.6.1.86.1	DisplayString	read-write	Filter MAC table to show only MACs associated with a given port range. The shorthand port format like 1 for 1/1 may be used. Syntax examples: mac.filter_port = 1/2,1/5 or mac.filter_port = 1-3,5.
STR macFilterUserPorts	1.3.6.1.4.1.3181.10.6.1.86.2	DisplayString	read-write	Filter MAC table to show only MACs associated with user ports. This excluded the links. This view eliminates MACs which are not of local interest. No parameter is required.
STR macFilterVlan	1.3.6.1.4.1.3181.10.6.1.86.3	DisplayString	read-write	Filter MAC table to show only MACs associated with a given VLAN range. Supply VLAN ID as parameter. Syntax example: mac.filter_vlan = 1-4,1000-2000.
STR macFilterMac	1.3.6.1.4.1.3181.10.6.1.86.4	DisplayString	read-write	Filter MAC table to find a specific MAC address and return the associated port and VLAN. Supply MAC address as parameter. Enter only the first 3 value pairs of the MAC to search for vendor MACs. Syntax example: mac.filter_mac = 01:22:3A.
STR macFilterCustom	1.3.6.1.4.1.3181.10.6.1.86.5	DisplayString	read-write	Filter MAC table according to supplied rules: [ -m MAC ] [ -s SEPARATOR ] [ -p PORTS ] [ -v VLANS ] or do not enter any parameter and see all MACs.
STR macFilterMulticastVlan	1.3.6.1.4.1.3181.10.6.1.86.6	DisplayString	read-write	Filter MAC table to show only multicast MACs associated with a given VLAN range. Supply VLAN ID as parameter. Syntax example: mac.filter_multicast_vlan = 1-4,1000-2000.
STR macFilterMulticastPort	1.3.6.1.4.1.3181.10.6.1.86.7	DisplayString	read-write	Filter MAC table to show only multicast MACs associated with a given port range. Supply port as parameter. The shorthand port format like 1 for 1/1 may be used. Syntax examples: mac.filter_multicast_port = 1/2,1/5 or mac.filter_multicast_port = 1-3,5.
STR macClearLearnedMacTable	1.3.6.1.4.1.3181.10.6.1.86.8	DisplayString	read-write	Wipe out all learned MAC addresses. Static entries are kept intact. No parameter required.
