Hi Guys,

I have a new topology:


    //       \\

  N2K     N2K

    |            |

Blade1   Blade2

Does anybody have a good example configuration of how to connect those devices? I´ve read the Cisco N5k and N2k configue guides but those guides didn´t show a good example configuration. I just need something simple with PortChannels and any other "special" configuration you can recommend.

Thanks in advance.

Dear Lucien,

What is the permissible distance between nexus 5000 and 2000 to act as FEX?

I am planning to have a 2k at ground floor and 5k at the first floor to provide 10th ports at both. Will this work ?

Thanks a lot,

With this topology you can't achieve HA at N5k level as you have only one. vPC will only work if you have two N5ks.
You can connect both blades to both N2ks using simple portchannel to achive HA at N2k level. The N2k only looks likes a linecard of N5k. Finally use tlb teaming at server level.
