| Some vendors provide a way to virtually stack multiple standalone devices by connecting them by their regular ethernet ports. Typically, one device in such a stack is assigned the role of //commander//, while the other devices take the role of //members//. The commander will have an IP address and provide management facilities for the stack as a whole. **BUT**, the commander will not present the stack as a single physical unit to the management station. Each device in this stack operates independently of one another; the commander will allow the management station to communicate with each stack member by addressing them with a modified SNMP community string - in essence relaying SNMP communication between the members and the management station. | Some vendors provide a way to virtually stack multiple standalone devices by connecting them by their regular ethernet ports.
