rapid spanning tree

Hi there,

I have a 4510R Device. Also some WS-C3750 Edge Switches connected to them. So if I connect a C3750 Switch to the 4510R Switch an another C3750R Switch to the 4510R Switch and connect both C3750 Switches together I have a loop. I have configures the rapid spanning tree protocol and all works weel and fast. On all Interfaces-Links I have a green LED. Is this right, ore shoud one link-LED be red (the one which his on standby)? thanx alot for your help!

Re: rapid spanning tree

You will not have an amber light unless the ports are in access mode and blocking. If they are trunking all lights will be green if the ports are operational. Use the "show span" command to find out which ports have a blocked state. You will only see it being blocked on one side.
