I have two different model's of GLC-T SFP's. One is PN 30-1410-02 the other is PN 30-1410-03. The -02 will not work in Nexus 5020 or an ASR-1000 router that I have, but works fine in my Cisco Wireless Controller. The -03 works fine in any device. My problem is when ordering, you can not specify the -03 they get ordered as GLC-T and none of my suppliers can assure me that I would get the -03 What is the difference between these two?
I have this problem too.
