Please help me on these.
I have 2 no?s of 6506, connection as shown below. The connectivity is Ethernet from MUX to the switch. The link to the switch A is up and I am able to ping to the Switch A by connecting the laptop instead of the switch B, the connected interface is in Half Duplex and 100Mbps. But at the switch B I have connected the 1000Base-T (GLC-T) to the slot WS-X6724 SFP the interface shows Full Duplex 1000Mbps and the status is down. I am not able to change the speed and Duplex at the switch B. if I change the speed at the switch A the interface goes down.
6506 A---MUX A-------------MUX B---6506 B
Please let me know what I need to do at the switch B for the link to work.
