What Is RADLAN-3SW2SWTABLES-MIB?
RADLAN-3SW2SWTABLES-MIB is a RADLAN/Marvell proprietary MIB (RADLAN being the switch-software OEM later acquired by Marvell) defining private tables that coordinate switching information shared between Layer-3 and Layer-2 forwarding on Marvell-based switch silicon. It belongs to the switch forwarding-plane/software category and exposes configuration for polling behavior between the L3-to-L2 switching table synchronization mechanism. Its monitoring relevance is largely software/internal-state health: the polling interval object controls how frequently the switch synchronizes L3 forwarding decisions down to L2 switching tables, and monitoring it (along with any associated status objects in the full tree) can help diagnose forwarding-table staleness or inconsistency between routing and switching layers. No dependency on other standard MIBs is stated, consistent with this being a low-level, self-contained OEM-silicon MIB. It is typically deployed on white-box or OEM switches built on Marvell/RADLAN switch chipsets that perform combined L2/L3 forwarding. Engineers can download the RADLAN-3SW2SWTABLES-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-3SW2SWTABLES-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.
What Can Be Monitored
- L3-to-L2 table synchronization polling interval
Supported Devices
- Marvell/RADLAN-based switch
Monitoring Examples
An administrator would poll rl3sw2swTablesPollingInterval to confirm how frequently the switch's internal process reconciles Layer-3 routing table entries into the Layer-2 switching hardware tables. Since this is the only sample object available, a broader monitoring scenario involving specific table entries cannot be honestly constructed; in practice an unusually long polling interval value could explain observed delays between a routing change and its reflection in actual Layer-2 forwarding behavior.
