We have two stacked cisco catalyst3750s and each switch has a port which connects to our providers switches and all traffic is routed out through these ports. Would I be correct in thinking that if one of these ports were to go down, as the switches are stacked the traffic would be routed though the other port?
The reason I ask this first question is because currently the switch ports are set to auto negotiate and I want hard set the speed and the duplex to match the providers ports. So my second question would be if I hard set the port on switch1 would I be able to test this to see it worked before changing the port on switch2? Initially I thought about using the ping x.x.x.x source fastEthernet command but it gave an error that an IP needed to be enabled on that port. Is there any way of testing this connection is working?
