Description: Defines the alert and trap notifications used by LANoptics network hub devices.

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 LANOPTICS-ALERTS-MIB?

LANOPTICS-ALERTS-MIB is a vendor-specific MIB from LANoptics defining alert and trap notifications for their network hub devices. Its role is narrowly focused on faults and notifications rather than broad configuration or performance data, generating SNMP traps when the hub detects abnormal conditions. In terms of hardware/software status monitoring, such alert MIBs typically cover things like port or segment failures, hub module insertion/removal, and other operational fault conditions relevant to a shared-media hub. Being a legacy vendor MIB, it likely depends on the broader LANoptics enterprise MIB tree for object identification and possibly on standard SNMPv2 trap conventions. It would have been deployed in older Ethernet/token-ring hub-based LANs from the LANoptics product line, where LANOPTICS-ALERTS-MIB SNMP monitoring provided early warning of hub-level fault conditions.

IPNetwork Monitor allows you to monitor SNMP objects defined in LANOPTICS-ALERTS-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

Only the generic IMPORTS clause was present in the source material for this MIB, so no concrete object or table names are available to describe a specific polling or trap scenario; based on its stated purpose, an NMS would register to receive the traps defined here to be alerted to hub-level fault conditions as they occur.

OIDs

OID symbolic	OID numeric	Type	Access	Description
lanOptics	1.3.6.1.4.1.224
alerts	1.3.6.1.4.1.224.9
alerts_mgmt	1.3.6.1.4.1.224.9.2
INT lanOpticsAlertsEnabled	1.3.6.1.4.1.224.9.2.1	INTEGER	read-write	A boolean variable that defines if the agent is sending alerts (traps) or alerts are disabled due to high frequency of alerts generation (see RFC-1224), regarding this manager enabled - 1 , disabled - 0.
INT lanOpticsMaxAlertsPerTime	1.3.6.1.4.1.224.9.2.2	INTEGER	read-write	Defines the maximum alerts allowed in lanOpticsWindowTime interval before an 'lanOpticsAlertsDisabled' trap is issued and 'lanOpticsAlertsEnabled' is set to 0 (see RFC-1224).
TIK lanOpticsWindowTime	1.3.6.1.4.1.224.9.2.3	TimeTicks	read-write	Defines the time interval in centiseconds, in which no more than 'lanOpticsMaxAlertsPerTime' may be sent before a 'lanOpticsAlertsDisabled' trap is issued and 'lanOpticsAlertsEnabled' is set to 0 (see RFC-1224).
INT lanOpticsMaxLogTableEntries	1.3.6.1.4.1.224.9.2.4	INTEGER	read-only	Defines the number of alerts saved in the lanOpticsAlertsTable below.
INT lanOpticsCurrentAlertId	1.3.6.1.4.1.224.9.2.5	INTEGER	read-only	Holds the last alert ID in the lanOpticsAlertsTable
lanOpticsAlertsRegisterTable	1.3.6.1.4.1.224.9.2.10		not-accessible	Each entry in this table, designated by the four digits of an IP address, defines if this address is registered to receive traps by the agent.
lanOpticsAlertsRegisterEntry	1.3.6.1.4.1.224.9.2.10.1		not-accessible
INT lanOpticsAlertsRegister	1.3.6.1.4.1.224.9.2.10.1.1	INTEGER	read-write	A boolean variable that is set (to 1) if the manager wants to be registered to receive SNMP traps, and is set to 0 if not.
INT pysmiFakeCol913	1.3.6.1.4.1.224.9.2.10.1.4294967292	INTEGER	not-accessible
INT pysmiFakeCol912	1.3.6.1.4.1.224.9.2.10.1.4294967293	INTEGER	not-accessible
INT pysmiFakeCol911	1.3.6.1.4.1.224.9.2.10.1.4294967294	INTEGER	not-accessible
INT pysmiFakeCol910	1.3.6.1.4.1.224.9.2.10.1.4294967295	INTEGER	not-accessible
lanOpticsAlertsTable	1.3.6.1.4.1.224.9.2.11		not-accessible	This table contains the last lanOpticsMaxLogTableEntries alerts that have been issued by the agent. Some of these alerts may have not been sent if lanOpticsAlertsEnabled is FALSE. The table is used to enable the manager to poll alerts. The first alertId can be retrieved by get-next on the table's object ID, and the next by get-next on the first one and so on.
lanOpticsAlertsEntry	1.3.6.1.4.1.224.9.2.11.1		not-accessible
INT lanOpticsAlertId	1.3.6.1.4.1.224.9.2.11.1.1	INTEGER	read-only	Give the manager a mean to get the first alertId by a GET-NEXT (see RFC 1224).
OCT lanOpticsAlertData	1.3.6.1.4.1.224.9.2.11.1.2	OCTET STRING	read-only	An Internal description of the alert to be polled by a StarNet Trapper.
