Hi,
I've a number of Edgerouter Pro's and have just configured an interface on each of 3 units to be fixed at 10BaseT full duplex. I have connected these ports to 3 different ZyXEL switches, which are also set to 10BaseT FDX. The interfaces come up on all boxes and say they are happy.
However, I get errored packets at all interfaces. If I change the interfaces to 100BaseT FDX the problems go away. I'm not sending large bit rates, so I'm not over subscribing the ports, but they behave as if they have come up as half duplex.
Does anyone else have experience of the same thing?
