In one embodiment, a system and a method may provide a command protocol and format for communication between a network interface card (NIC) and a management device such as, for example, an intelligent management device (IMD). An interface may be adapted to allow the management device to merge its traffic with that of the NIC to provide a fully integrated management solution. The fully integrated management solution may be implemented, for example, without additional network connections. ## Claims ### Claim 1 A communications system, comprising: a first host network interface card (NIC) coupled to a network; a second host NIC coupled to the network; and a manager coupled to the first NIC and the second NIC, the manager initially being in two-way communications

14 (depends on 12) The system according to claim 12, wherein the command and the corresponding response each comprise an identical sequence number. ### Claim 15 (depends on 12) The system according to claim 12, wherein the manager stores a particular command until a corresponding response has been received. ### Claim 16 (depends on 7) The system according to claim 7, wherein the manager comprises an intelligent management device. ### Claim 17 (depends on 1) The system according to claim 1, wherein the manager comprises a management processor and a MAC, the management processor being coupled to the MAC, the MAC being coupled to the first NIC. ### Claim 18 (depends on 16) The system according to claim 16, wherein the MAC of the manager is coupled to a MAC of the first NIC. ### Claim 19 (depends on 1) The system according to claim 1, wherein management traffic, commands and responses are passed between the first NIC and the manager. ### Claim 20 (depends on 1) The system according to claim 1, comprising: a plurality of additional host NICs, each additional host NIC being coupled to the manager, wherein if the first NIC and the second NIC fail, then the manager selects a host NIC
