Nexus 1000v management interface

Hi,

not sure if this is the place to ask or not, if not if you can direct me to the correct place that would be great.

I  have a Nexus 1000v on a esxi server. The server has two NICs that go to  two different switches that are completely isolated from each other. I  have a vSwitch set up that can access the vCenter, and a port from the  1000v is attached to that vSwitch - that uses NIC1.

NIC2  is attached to the 1000v in the UPLINK port-profile, and I can reach a  bunch of hosts and the Vmk0 that I added to the Control Port-profile  (maybe not the right place to add it - but it works)

here is the config of the 1000v

version 4.2(1)SV1(5.1)

Now  comes my problem, I have a NMS attached to a c3750 on NIC2 that would  really like to manage the 1000v itself however I can't figure out how to  get the two to talk.

I've  put the same network on basically all the Vethernet port-profile vlans,  but can't get to the mgmt0 interface, and can't put ip address on  anyother interface. It seems like it only wants to talk on interface two  in the vmware host definition ... What am i missing

Any help would be great

Hello Ken,

The mgmt0 IP address (NIC 2 on the VM as you say) must be accessible from the NMS. From your description, it looks like the connection is:

    Switch 1          Switch 2 -- NMS

       |                           |

       |                           |

       |                           |

      NIC 1                  NIC 2

    -----------------------------------------

     vSwitch          Nexus 1000v

       |

       |

    VSM VM NIC 2

If this is correct, then you need to either connect switch 1 and switch 2 or move the VSM VM's NIC 2 nehind the Nexus 1000v.

Thanks,

Shankar
