Hi Guys,

I have a Cisco 1000 Border router here for one of our frame-relay connections.

I am getting many collisions on the 10MB Ethernet0 interface. The other end is connected to our Pix and that interface is set to autonegotiate as thats the only way I can get it to come up. The only IOS command I can see under the Ethernet0 interface seems to be the bandwidth command much like that of a frame-relay serial interface, so I set that to 10000.

Does the interface simply not support full duplex operation? Is an IOS upgrade needed, would this help?

I wonder if someone could tell me how to either hardset the unit to full duplex or if it doesn't support full duplex operation

Or are there such things as a 10/100 Ethernet Card Interface for what appears to be an expander slot next to the frame serial interface connector on the router.
