What is snFdbTableCurEntry?
This OID stores a count of how many MAC addresses (unique device identifiers on a network) are currently configured in the switch's forwarding database. This number tells you how many devices the switch has learned about and is actively tracking on the network. A network operator would monitor this value to detect unusual changes in device activity, such as a sudden drop indicating network disconnections or a spike indicating a scan attack.
