What is acdSmapL2FilterTableLastChangeTid?
This OID stores a transaction ID counter that increments each time the Layer 2 (MAC-level) filter table is modified. Network engineers monitor this to detect changes to the filter configuration without having to read every single filter rule. For example, if the value changes from 42 to 43 since your last check, one modification was made to the L2 filter settings.
