A media selection system includes a plurality of media ports. Each of the plurality of media ports is coupled to a corresponding physical medium, and each of the plurality of media ports is configured to generate an activity signal and a link status signal. A priority storage module is configured to contain priority information, which sets forth a priority for establishing a link through each of the plurality of media ports. A media selector module is configured to select a first media port through which a link will be maintained based on the link status signal generated by each of the plurality of media ports and the priority information. The media selector module is further configured to block all other links through media ports of the plurality of media ports other than the first media port.

1. A media selection system comprising: a plurality of media ports, each of the plurality of media ports being coupled to a corresponding physical medium, each of the plurality of media ports being configured to generate an activity signal indicting whether activity is sensed on the corresponding physical medium associated with the media port, andgenerate a link status signal indicating a network link status through the corresponding physical medium associated with the media port;a priority storage module configured to contain priority information, the priority information setting forth a priority for establishing a link through each of the plurality of media ports; anda media selector module configured to select a first media port of the plurality of media port through which a link will be maintained based on (i) the link status signal generated by each of the plurality of media ports and (ii) the priority information, andblock all other links through media ports of the plurality of media ports other than the first media port,wherein, in response to an activity signal being generated by a second media port having a higher priority than the first media port, the media selector is configured to block all other media ports other than the second media port responsive to a link being established through the second media port. 2. The media selection system of claim 1, wherein the priority information associates each of the plurality of media ports with a unique priority level. 3. The media selection system of claim 1, wherein the priority storage module comprises one or more of an application specific integrated circuit (ASIC), an electronic circuit, a processor, a combination logic circuit, or a memory. 4. The media selection system of claim 1, wherein the first media port has a highest priority among other media ports of the plurality of media ports having an established link. 5. The media selection system of claim 1, wherein the plurality of media ports comprise one or more of a fiber 1000BASE-X port, a parallel 10GBASE-X port, a serial 10GBASE-R/10GBASE-W port, or a copper 10GBASE-T/1000BASE-T/100BASE-TX/10BASE-T port. 6. The media selection system of claim 1, further comprising a media independent interface configured to connect to the first media port. 7. The media selection system of claim 6, wherein the media independent interface comprises a XAUI interface. 8. The media selection system of claim 6, wherein the media independent interface comprises an extended XGMII interface. 9. A method for selecting a media port from among a plurality of media ports through which a link will be maintained, each of the plurality of media ports being coupled to a corresponding physical medium, the method comprising: for each of the plurality of media ports, generating a link status signal indicating a network link status through the corresponding physical medium associated with the media port;selecting a first media port of the plurality of media port through which a link will be maintained based on (i) the link status signal generated by each of the plurality of media ports and (ii) priority information, wherein the priority information sets forth a priority for establishing a link through each of the plurality of media ports; andblocking all other links through media ports of the plurality of media ports other than the first media port,wherein, in response to activity being sensed on a corresponding physical medium associated with a second media port having a higher priority than the first media port, blocking all other media ports other than the second media port responsive to a link being established through the second media port. 10. The method of claim 9, wherein the priority information associates each of the plurality of media ports with a unique priority level. 11. The method of claim 9, wherein the first media port has a highest priority among other media ports of the plurality of media ports having an established link. 12. The method of claim 9, wherein the plurality of media ports comprise one or more of a fiber 1000BASE-X port, a parallel 10GBASE-X port, a serial 10GBASE-R/10GBASE-W port, or a copper 10GBASE-T/1000BASE-T/100BASE-TX/10BASE-T port.
