Host OS install


I am trying to set-up and UCS -B series blade server from scratch.

The network admin has powered up the hardware with fabric interconnects and I am able to access the kvm console for the blade.

Next step was to install Ubuntu as the host os which was successful.

While installing Ubuntu, I have assigned IP address for this blade. However, this IP address is not reachable from the external world.

I am looking for a guide/document which can help me network access to this blade.

Thanks for your time.

Most likely this is a trivial problem.

Q. How did you define your virtual ethernet interfaces in the service profile: one vlan per veth ? or multiple (vlan trunk) ?

Most likely it's one; then you might try to select this vlan as the native vlan; your Ubuntu might not expect 802.1Q trunked Ethernet frames !

Thanks Wdey for your response

Thanks Wdey for your response.

Looks like it is a vlan configuration issue. I am working with the admin to get this fixed.
