I just moved into a new job and I had C9500-40X's and Firepower 2120's waiting for me. However when I looked into those model numbers the C9500's are fully 10GB and the FPR2120's are 1GB. Has anyone had success with using a 10GB copper SFP and have the 9500 auto negotiate down to 1GB?
Solved! Go to Solution.
I don't see any copper SFP (1Gig) for the model you are using. There is GLC-TE support if the firepower appliance come with any copper gig ports or support GLC-TE
see link and look under c9500-40X
