Hi,
If so, what ports does support 802.3bz standard? In config mode there is possibility to check box for 2.5g.
I plan to buy PCI express card witch 2.5g supported. Please confirm. Do I need to buy SPF module too?
Only the SFP+ ports support 2.5G, and only when you use a multi-rate SFP+ in them, like the S+RJ10.
