This RowStatus object controls creation and deletion of entries in a table of MAC addresses that are explicitly permitted to bypass Layer-2 isolation, using the standard active/createAndGo/destroy actions the description calls out. An administrator adds a specific device's MAC address to this table when that one device (like a shared printer or an access point management interface) needs to remain reachable by other isolated hosts despite Layer-2 isolation being enabled on the VLAN. For example, setting this to createAndGo(4) for a printer's MAC address would let hosts on an otherwise-isolated VLAN still print to that shared device.
