A few other thoughts on the Nexus difference from a 6500 based on my experience since I am still learning the 7K platform:
1) MPLS the 7K is VRF Light syle 2) Application of an access-list by doing a tftp->run (with out removing the acl which is applied to the interface) is extremely taxing in the system and very slow. The Nexus seems to recompile the ACL after each line there are work arounds vs have the acl upload completely and recompile once. 3) Nexus STP is RSTP not pvst+ 4) The TACACS implimentation of this platform seems incomplete. TACACS is useable, but local-admin accounts must be configured and used for configuration. 5) The layout of the configuration is different (as someone mentioned) Features must be enabled (ie., ospf,tacacs must be enabled by using 'feature ???') if ospf feature is not enabled, it can't be used until it's enabled (not configured). OSPF is configured mostly under the interface (passive-interface, process # vs globally) HSRP is configured like an interface where you enable the hsrp #, then you are in a config-hsrp# mode where you then finish the hsrp config. HSRP is not just configured under "router(conf-if)#" 6) QoS you specify the queueing structure (ie., 1P2q4T) and not the queueing or scheduling or thresholds. Obviously there is the ability to tweak the QoS, but the base config viewing is much simpler 7) Obviously there are many hardware differences (Resilient Sups which are better than the dual-sup on the 6500), transfering the configuration from a 6500 to a 7K (ie., replacing a 6500 with a 7K) is pretty challenging. Think of it from going from CatOS to CATIOS and having to create a script to migrate your config (trunk, vrf) to the 7K. Just some thoughts...

So if you have slower speed kit like console servers or tiny boxes or whatever, you will need to cope with these separately.
