Anyone ever hear of the SGMII Gigabit Ethernet interfaces on these? They are every other pair.
So,
SGMII == 3,4,7,8,11,12,15,16,19,20,23,24
RGMII == The rest of the ports
What is happening is, a LOT of desktop/server NIC's have issues connecting or staying connected to Cisco's SGMII interfaces. Cisco's solution? Blame the damn NIC and tell me to only use the RGMII ports. Pretty exensive 12 port switch I must say! This is happing on Intel PRO1000 CT and MT, Via Rhine II 100Mbit, and Realtek 100Mbit NICs so far! Cisco briefly mentions this ONLY for one NIC and blames it on Intel in CSCea77032 . Why the hell are they selling a switch where half its ports are using a BARELY IMPLEMENTED new standard, without putting a big red freaking stamp on these ports? Instead, there is only an obscure mention in the release notes relating to one particular NIC. TAC tells me it's only Intel, when I have demonstrated other NIC's doing the same thing. The second I plug any of these into one of the RGMII ports, all is well. Cisco's "fix" of forcing speed/duplex has no effect! I am so freaking mad right now, I spent all day on this. Anyone else hear of this? What is the solution?
