I have downloaded vshield manager 5.5 .Ova and log in to vshield inteface. In installatin guide documentaion is mentioned that:
**********************
You must install a CIS or vCloud Networking and Security (vCNS) license before installing vShield App
and vShield Edge. The vSphere license includes a license for vShield Endpoint. You can install these licenses
after vShield Manager installation is complete by using the vSphere Client.
Procedure
1 From a vSphere Client host that is connected to a vCenter Server system, select Home > Licensing.
2 From the Management tab, select Asset.
3 Right-click a CIS or vCNS asset and select Change license key.
4 Select Assign a new license key and click Enter Key.
5 Enter the license key, enter an optional label for the key, and click OK.
6 Click OK.
7 Repeat these steps for each vShield component for which you have a license.
*******************************
But there is no any aaset in licencing section of vsphere client...
