Well most importantly Nexus does 10Gig with the promise of Fibre Channel over Ethernet (FCoE) in the future. You can also add Fibre Channel modules to the Nexus line and not the catalyst line. It runs NX-OS instead of IOS which I believe came out of the Storage OS side of Cisco. The Nexus is also much higher performance overall in terms of switching capacity and for the most part isn't oversubscribed. The Catalyst line has the ability to do Layer 3 that you can't do on the Nexus. It also has Power of Ethernet which you need for VoIP, security cams, etc...The Designs I typically see out of Cisco right now are using Nexus for the Core with a 4900M to handle the Layer 3 stuff. Then they use Catalyst for the Access Level to workstations and such. They both have their place and it depends largely on what you are trying to accomplish. |

NX-OS also supports virtual port channel. https://cisco.com/en/US/prod/collateral/switches/ps9441/ps9402/white_paper_c11-516396.html |

What L3 stuff does the Nexus not do? You must be talking about the Nexus 5000 surely, because the Nexus 7000 has a whole bunch of L3 features. |

pressureman is correct. The nexus 5000 is only L2. Nexus 7000 series allows you do do a pile of stuff. I also like that you don't have to run the "do" command all the time. |
