Description: Hirschmann HiOS (HM2) port security MIB for MAC address-based port access control 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 HM2-PLATFORM-PORTSECURITY-MIB?
HM2-PLATFORM-PORTSECURITY-MIB is a Hirschmann (Belden) HiOS platform MIB (HM2 private platform subtree) for configuring port security, a feature that restricts network access on a switch port based on learned or configured MAC addresses. It exposes a global port security mode switch and a per-port security configuration table controlling the feature's behavior on individual switch ports. This MIB's monitoring value is centered on software/access-control status: hm2AgentGlobalPortSecurityMode shows whether port security is enabled fleet-wide, and hm2AgentPortSecurityTable entries let an administrator confirm per-port enforcement state, useful for detecting a port that should be locked down but isn't, or one that has triggered a security violation. It is a Hirschmann-proprietary module within the broader HM2 private-platform MIB family, relying on that platform's general port/interface indexing conventions. It is typically deployed on Hirschmann industrial managed Ethernet switches in factory automation and critical-infrastructure networks where physical port access must be tightly controlled. Engineers can download the HM2-PLATFORM-PORTSECURITY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HM2-PLATFORM-PORTSECURITY-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
- Hirschmann HiOS-based industrial managed Ethernet switches
Monitoring Examples
A security administrator would poll hm2AgentGlobalPortSecurityMode to confirm the feature is enabled network-wide, then walk hm2AgentPortSecurityTable (via hm2AgentPortSecurityEntry) to verify each port's individual security configuration matches policy, catching a port that was left in learning/open mode when it should be locked to specific MAC addresses. An unexpected change in a port's entry could indicate an unauthorized device attempted to connect and triggered a security action.
What Can Be Monitored
- global port security mode
- per-port security configuration
- port security enforcement state
