    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;OK, if it's in production, need to be fixed via esxcli.&lt;/P&gt;&lt;P&gt;Apparently, the Management VMKernel is removed from the Management Port group as it says "0.0.0.0" on the third screenshot.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Just to make sure, run &lt;EM&gt;&lt;STRONG&gt;esxcli network ip interface list &lt;/STRONG&gt;&lt;/EM&gt;to check if there are any VMKernels.&lt;/P&gt;&lt;P&gt;It won't generate any output if there is none.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Now, run &lt;EM&gt;&lt;STRONG&gt;esxcli network ip interface add -i=vmk0 -p="Management Network -M="MAC Address"" &lt;/STRONG&gt;&lt;/EM&gt;to create a VMKernel for management. It is very &lt;EM&gt;&lt;STRONG&gt;important &lt;/STRONG&gt;&lt;/EM&gt;to put in the right MAC Address of the Uplink (in your case, the MAC Address of vmnic1, 5c:f3......)&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;One thing to note is vmk(number) should be the number that doesn't conflict. For example, if there are 2 VMKernels, vmk0 and vmk1, vmk2 should be used.&lt;/P&gt;&lt;P&gt;Now, you will be able to configure the Management Network via DCUI.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you want to set ipv4 settings via esxcli, run &lt;EM&gt;&lt;STRONG&gt;esxcli network ip interface ipv4 set&amp;nbsp; -i=vmk0 -I=x.x.x.x -N=x.x.x.x -t=static&lt;/STRONG&gt;&lt;/EM&gt;&lt;/P&gt;&lt;UL&gt;&lt;LI&gt;-i is the VMKernel name&lt;/LI&gt;&lt;LI&gt;-I (capital i) is the Management IP Address&lt;/LI&gt;&lt;LI&gt;-N is the subnet mask&lt;/LI&gt;&lt;LI&gt;-t=static represents it will be a static IP Address, not DHCP&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Hope this helps.&lt;/P&gt;&lt;P&gt;Steven.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;hi guys&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I had some networking issues so I had to remove one vmnic from the management network made of vmnic0 - vmnic1. I had to remove vmnic0&lt;/P&gt;&lt;P&gt;In six servers removing vmnic0 worked OK, but in this server gave me some errors I think since I don't remember pretty well related with IPv6...&lt;/P&gt;&lt;P&gt;the problem with this server is after the error Network Settings are disabled and I am not able to reconfigure vmnics in fact now server has no IP&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;any idea how to fix this, directly in the cli console I see the vSwitch0 which has the Management Network, which I fact I tried leaving only vmnic1 is not working yet&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="vSw.png"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/46478iF2D05C19359EADEB/image-size/large?v=v2&amp;amp;px=999" role="button" title="vSw.png" alt="vSw.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="vmnic.png"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/46472i379AE29D4064B5BB/image-size/large?v=v2&amp;amp;px=999" role="button" title="vmnic.png" alt="vmnic.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="Disabled.png"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/46473i0DDBD2E21DE0679F/image-size/large?v=v2&amp;amp;px=999" role="button" title="Disabled.png" alt="Disabled.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="ip.png"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/46474i2EBA75A570571296/image-size/large?v=v2&amp;amp;px=999" role="button" title="ip.png" alt="ip.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;thanks a lot&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi, If this ESXi isn't in a production yet, I would recommend you to restore the network settings. It takes time to fix using esxcli! Network Restore Options -&amp;gt; Restore Standard Switch Regards, Steven.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;If your network is down, then I am wondering how your Server is still under production. It might be that the virtual machines portgroups are managed by a different vswitch with another uplink.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;However, coming to your topic, the "greyed out" options might arise if you have enabled DHCP and the removal of the vmnic0 lead to reclaiming of the IP based on the new mac address from vmnic1 which for many reasons could fail. [dhclient timing out on vmnic1, no ips, still queries with vmnic0 mac address]&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I also find that the VMkernel port is treated as a virtual machine portgroup instead of management.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Check this page, since it almost similar to your case. &lt;A href="http://vmtoday.com/2012/02/vsphere-5-networking-bug-2-affects-management-network-connectivity/" title="http://vmtoday.com/2012/02/vsphere-5-networking-bug-2-affects-management-network-connectivity/"&gt;vSphere 5 Networking Bug #2 Affects Management Network Connectivity - VMtoday&lt;/A&gt;&lt;/P&gt;&lt;P&gt;Also, I would suggest, to unlink the vmnic1 from the vswitch0 and delete the portgroup Management_network and create a new one as suggested by skan with &lt;/P&gt;&lt;P&gt;esxcfg-vmknic -a - i DHCP -p VMKernel&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
