I have cisco 7220's, would like to utilize the 10 gig interfaces to connect to 1 gig uplinks on the otherside. Being told this will work. unable to get it to work though. Being told that I need to use the SFP+ 10gig on the Aruba side and then can connect into a Cisco Single-Mode-LX on the otherside. The Aruba side will negotiate down to 1gig, so far I am not even getting a link.
