can someone please tell me the config commands to set up ether channeling between 2 multimode fiber connection on a cisco switch. when i initial configured and plugged in my fiber there was traffic then it stopped and the ports shut down. no link lights at all. when i remove ether channel groups traffic resumes. i've editing the config so much i'm not sure what i changed and should keep at this point. thanks for any help.
switchport trunk encapsulation dot1q
switchport mode trunk
switchport non negotiate
spanning tree port fast trunk
i'm getting this when i do a show ether channel "port state down - not in bndl" what bundle?
