Hello,
I try to dual attach a 2960 to my 2 nexus on which peer link and keepalive are OK.
The ports are down (notconnect) on the 2 nexus, and I don't see any config error !
Another detail, when the SFP is plugged into the port, led is orange, whereas when I connect the fiber, led turns off
I join few config about the portchannel, and shows relative to this :

Please help if you find any configuration errors or tips to bring up the portchannel.
