Abstract
Example embodiments disclosed herein relate to passing or forwarding a frame. A frame is received from a first device. The frame includes a first header including a destination Media Access Control (MAC) address followed by a second header including a source MAC address followed by a third header including an Ethertype. The frame is passed or forwarded to a second device based on the Ethertype.
Claims15
A network device comprising:
- a communication module to receive a frame from a first device, wherein the frame includes a first header portion associated with a destination media access control address followed by a second header portion associated with a source media access control address that is followed by a third header portion associated with an Ethertype;
- and
- a pass through module to determine whether to pass the frame to a second device, without modification of the frame, based on the Ethertype.
A non-transitory machine-readable storage medium storing instructions that, if executed by at least one processor of a device, cause the device to:
- receive a frame from a first device, wherein the frame includes a first header field including a destination media access control address followed by a second header field including a source media access control address followed by a third header field including an Ethertype;
- parse the frame to determine the Ethertype;
- and
- determine whether to pass the frame to a second device based on the Ethertype.
A method comprising:
- receiving a frame from a client device wherein the frame includes a first header field including, a destination media access control address followed by a second header field including a source media access control address followed by a third header field including an Ethertype;
- parsing the frame to determine the Ethertype;
- and
- forwarding the frame to a second secure device based on the Ethertype.
