Its playtime. I am fortunate enough to have the following unboxed and at my disposal for some time.


It is two Cisco Nexus 7010 chassis, meant for a another new 10Gb DC coming online soon.
Each comprise of the following configuration:

  • 2x SUP-1’s: First generation Supervisor.
  • 3x FAB-1: Cross connect Fabric card module.
  • 2x N7K-M132XP: M1-Series 32-Port 1/10Gb Ethernet Module, 80Gb Fabric.
  • 1x N7K-M148GS: M1-Series 48-Port 1Gb Ethernet Modules, 46Gb Fabric.

The the other switches are:

  • 2x Nexus 5010’s
  • 2x Nexus 2224TP (Fabric Extender)
  • 3x Catalyst 3750G
  • 1x Lost Catalyst 2960.

Unfortunately I do not have a F1 series linecard, it would be interesting testing Cisco FabricPath, but I can test OTV (Overlay Transport Virtualization). The messy cable configuration was done for that exact purpose, to test OTV. ;D

So in the next couple days I will cover the theory, configuration, pro’s and con’s of using OTV as a DCI (Data Center Interconnect).

    How could you get 1 Gb port on this card?

    1. Hello
      That is a 10Gbe linecard only.
      The ‘show int cap’ illustrates that the port can only connect at 10Gbe:
      “Speed: 10000”

      For 1Gbe ports you would need the 48-port 1Gbe linecard.
      hth :)
