A couple of days ago I had a strange problem on newly deployed VMware ESX hosts which were added to Cisco 1000V Distributed Virtual Switch. Both, the Management Network and vMotion interfaces were OK but VMs on any other port groups did not have network connection. The UCS server profiles were configured correctly and all necessary VLANs were presented on the vNICs. As a test, I created a new Standard Switch, configured a Port Group and put a test VM on it. It worked just fine. It was time to troubleshoot Cisco 1000V DVS… As there were already a few hosts configured on Cisco 1000V switch, I was confident that the basic configuration was correct. It turned out to be the licensing issue. Unfortunately, there are times when we built new ESXi hosts at a faster rate than we add licenses… :)

Please refer to “Cisco Nexus 1000V Switch for VMware vSphere Licensing Information“.- You will be sent a PAK (Product Authorization Key) which you need to register with Cisco;
- Login to www.Cisco.com, Support, Manage Software, Register and Manager Licenses, click on “Continue to Product License Registration”;
- Enter PAK or click ‘Load More PAKs…’ to register multiple PAKs, click Fulfill Selecte PAKs;

License hostid: VDH=9623761541319554XXX - Click Assign, click Next;
- Select End User, confirm that the email address is correct, click on Get Licenses. The licenses will be emailed to you in a .ZIP file or you can download them straight away;
- If you registered multiple PAKs or split up license, you will get multiple license files (.lic). If you don’t remember which one is for which 1000V switch – no problem: a) you will not be able to add license that is assigned to another switch (different host ID) and b) license file contains the switch host id:
