  • Four main platforms in the CCIE DC Lab Exam
    • Nexus 7K
    • Nexus 5K
    • Nexus 2K
    • Nexus 1K
  • http://www.cisco.com/go/nexus 
  • Cool App for the IPAD is the Cisco 3d Catalog IPAD app 
  • Currently 4 form factors
    • 7018,7010,7009, and 7004
  • Currently 2 types of lines cards
    • M Series Cards - Layer 3 cards
      • Feature rich cards
    • F Series Cards- Layer 2 Only (Can support Layer 3 no OTV, LISP, MPLS)
    • Have to be cognizant of the Allocation of the ports per ASIC
      • For instance the M2 line card has ports 1,3,5,and 7 associated for one ASIC if in Dedicated mode only port 1 will be able to be active)
  • M series Specific 
    • Layer 3 Routing (new F2/F2e modules do support this)
    • FEX (new F2/F2e modules do support this)
    • OTV 
    • TrustSec (link layer encryption MACSec)
  • F Series 
    • Layer 2/3 
    • FabricPath
    • vPC+
    • FCOE
  • M Series proxy routes on behalf of the older F series modules
  • Cannot wait for the F3 Modules to come out for the Nexus 7K!!!!!
  • Nexus 5K Overview
    • Nexus 5010 and 5020 1st Generation
    • Nexus 5548UP and 5596UP 2nd Generation
    • Nexus 5672UP and 56128P 3rd Generation (not on the Lab exam)
  • Mainly Layer 2 switching 
    • EOR (end of Row)
  • 5500 supports Unified Ports (UP Models)
    • Ports can run as Ethernet or Native Fibre Channel
    • Ethernet ports are from port 1 and up
    • Fibre Channel ports are from the last port counting down
      • When you change the role of the port it requires a reboot of the switch
  • Nexus 2K overview
    • Fabric Extender (FEX)
      • Remote line card of the parent switch Nexus 5K or 7K chassis
      • No Local switching (this could impact the design of your DC)
