Fiber connection question to Cisco 3560 switch
Posted on 2011-02-14
Hello, we are connecting a Cisco 3750 switch to a Cisco 3560 with Fiber. We have two SFP connectors in each switch. On the Cisco 3750, both connections are green. On the 3560, one is amber and one is green. We are able to send traffic from one switch to another but we aren't sure why one is amber. We want to combine the connectors so that we can send 2GB over the link. When we unplug either fiber connection on the Cisco 3560, the other connection turns green. My first question is why is one connection amber and secondly how do we combine the connections so that we can utilize 2GB. Thank you.
