ALCATEL-IND1-LPS-MIB

Description: Alcatel OmniSwitch learned port security MIB for managing MAC address learning limits and violation actions.

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.

ALCATEL-IND1-LPS-MIB is Alcatel's "IND1" enterprise MIB (for the OmniSwitch "Birds of Prey" product line) that manages Learned Port Security (LPS), a switch-port feature that limits and controls which MAC addresses are permitted to communicate on a given port. It exposes a per-port configuration and status table covering the maximum number of MAC addresses allowed to be learned, an acceptable MAC address range, the action to take on a security violation, and administrative/operational status for the feature on each port. Its monitoring value is primarily software/security status at the port level: administrators can check lpsOperStatus to confirm the feature is actively enforcing on a port, and use lpsRowStatus together with violation counters/settings to detect when a port has hit its learned-MAC limit or triggered a violation action (such as shutting the port down). It depends on the standard ifIndex convention from IF-MIB to associate LPS settings with physical switch ports. This MIB is deployed on Alcatel (now Alcatel-Lucent Enterprise) OmniSwitch Ethernet switches in enterprise LAN environments needing port-level MAC address access control. Engineers can download the ALCATEL-IND1-LPS-MIB file directly to load it into their MIB browser.

An administrator would poll learnedPortSecurityTable (learnedPortSecurityEntry) to check lpsMaxMacNum against the current learned-address count and confirm lpsAdminStatus/lpsOperStatus show the feature enabled and running on a given port. Reviewing lpsViolationOption reveals what action (e.g., port shutdown, drop, trap) will occur if lpsMaxFilteredMacNum is exceeded, and lpsLoMacRange/lpsHiMacRange define which MAC ranges are permitted. A port whose lpsOperStatus unexpectedly shows down alongside a security-violation trap would indicate an unauthorized device attempted to exceed the learned-MAC limit on that port.

Manages learned port security by tracking MAC address learning and port-based access control on Alcatel-Lucent switches.
