I have a WAAS device placed between two routers and two switches. One switch and router group autonegotiates perfectly fine 100mbps full duplex. The other router and switch group however does not. The switch port is gigabit and the router port is fastethernet. Here are the problems:
1. If I set all ports statically to 100mbps fullduplex the router port does not come up and my WAN 0 port which is connected to the router is up. My LAN 0 port that is connected to the switch is down and my switch port is up.
Now the obvious assumption is that I have the router connected to the LAN 0 port and the switch connected to the WAN 0 port. This is not the case however as if all ports are set to auto negotiate the LAN 0 negotiates at 1gbps full and the WAN port is 100 mbps full.
2. If I shutdown the port on the router manually my LAN 0 port goes down and not the WAN 0 port.
