I have a Cisco 9032 encoder. I see where to set the IP network information but I don't see where the devices auto-negotiation is set. My 7609 is set to 100/full hard set. I'm getting runt errors and I'm wondering is this due to the encoder not being able to do a 100/full. When the router is set to auto i'm getting 100/half. I would just like to know for sure if the encoder in fact only can do 100/half.
