Esxi host NIC Configuration question

Hello Experts,

 I have a ESXi with 4 NIC's on it (Test Environment). I have configured vmnic0 for our ESXi Management netwtork and I have assgied an IP address to it from ESXi console.

 Now my question is ,

Rest of the 3 Adaptors have not been assigned any IP Address (They are Enabled). Do I need to assign an IP Address to them in order to use them for my vSwitches.

Because I see , I have a physical adaptor vmnic1 which is been assigned to my vSwtich1 .

Now the VM's in vSwtich1 are not able to ping and communicate with outside world.

Thanks,

-Prashant Girennavar.

No you do not need to assign IP Addresses to the remaning NICs.

The IP Address is assigned to the Management Interface of the ESXi server.

when nics are connected to a vSwitch, the network traffic is passed through the vSwitch to the VMs, which are connected via the Portgroup, the VM has the IP Address.

What do you want todo with the remaining 3 nics!

create teaming, virtual switch for VMs, VMKernel for iSCSI and NFS traffic which does require an IP Address.

If you want to read more on networking in VMware ESX/ESXi, then I recommend the following:-

I would also recommend reading through the Networking Sections of the following guides to gain a better understanding of Networking in VMware ESX/ESXi.

Pages 13 - 73 Discuss Networking in Detail, including trunks, VLANs, switches, and load balancing

Great.

So , No IP is required for Rest of the NIC's

I have already assigend an IP address to vimnic0 for management network.

Now, When I create a vSwitch 1 and add vimnic1(which dont have IP address) to it , the VM's which are in vSwitch 1 are unable to communicate withe VM's in vSwitch0 (where vmnic0 is attached with IP address).

Is my configuration wrong./...

Where I need to see , what is going wrong?

Thanks,
