Can someone tell me what's the difference between F2 and new F2e? All I can find is MACsec support. Is that it?
The biggest gripe (and Gotcha) when people purchased the N7K-F248XP-25 (aka standard F2) is one inability of this line card to work with M1/M2 and F1 card. The F2 has be in it's own little VDC. No one in Cisco would admit that this was due to an engineering fault (or disaster).
So the F2e was born. Whatever the standard F2 can do, the F2e can do as well. And the F2e can work with M1/M2. And when this happens (as stated on the Data Sheet) "When deploying the Cisco Nexus 7000 F2e-Series Fiber Module in a VDC together with the Cisco Nexus 7000 M-Series modules, the Cisco Nexus 7000 F2e-Series Fiber Module will run in Layer 2-only mode, delegating all Layer 3 capabilities to the Cisco Nexus 7000 M-Series modules present in the VDC. The initial software release does not support this capability."
The F2e comes in two "shapes": 48-ports of either 1/10BaseTx or SFP/SFP+
Like the F2, the F2e will still not be able to support OTV (Integrating F2 Series Modules Into a Cisco Nexus 7000 Series System).
Due to the release of the new F2e card, expect Cisco to announce (in 6 months time) the end-of-sale of the standard F2 card. (My own opinion, read below for Cisco Nexus 7000 Production Management Team rebuttal.)
II am not sure what Cisco will do to clients who mistakenly purchased the standard F2. Will Cisco quietly allow them to trade or swap to F2e? Only people (like Jerry) in Cisco will know.
