Sorry if this is the wrong section, I was not sure if Hardware or General.
I have a Mac Mini with a 10G Ethernet port and am having issues connecting to a RB951G-2HnD and a 2011UAS-RM.
ROS : 6.48.2 ( though had this issue on previous versions)
I am using a 6 foot cat-6 cable (tried multiple different ones)
I can plug the 10G port into a 100 mbps port on the 2011uas and it will work on auto negotiate (although 100 mbps) and pass DHCP traffic.
I can plug the 10G port to a "dumb" Netgear 1 gbps switch and seems to work, as well as an old Linksys and 2 different ISP "Modems" and they work.
The problem comes when plugging into a 1gbps port on the RBs. It takes about 15 secs before the Mac OS reports the port auto negotiation as 100mbps.
No traffic seems to pass back and forth ( dhcp does not seems to work) and the os assigns a link local address.
I have tried manually setting the ports to 1gbps on both sides and no traffic seems to pass either.
Any suggestions for troubleshooting/solutions would be appreciated.
