TMS320C6678: Priority for SGMII0 and SGMII1

Hi Experts,

Is it possible to prioritize SGMII0 over SGMII1 somehow?
It seems that even though the DOS attack occurs on SGMII1, SGMII0 should work nomally without any influence.

Thank you very much for your skillful system level support.
Best regards,

Hi,

SGMII 0 and SGMII 1 are two separate ports connected to the 3-port GbE switch of C6678. There is no priority setting of one Ethernet port over the other. The host port of the switch connected packetDMA, as seen in the NETCP user guide.

Assuming one of the SGMII port is under the DOS attacked, the packerDMA maybe jammed, it also affects the other SGMII port.
