2 VPN licences on ASA 5520?

Ive got a customer asking for 2 products to be installed on an ASA 5520

ASA 5500 SSL VPN 10 Premium User License


AnyConnect Essentials VPN License - ASA 5520 (750 Users)

Am i correct in saying only one of those licences will actually be active at any time?

2 VPN licences on ASA 5520?

Anyone got any idea on this?

Re: 2 VPN licences on ASA 5520?


Here are the main difference between each other:

Anyconnect Essentials                                                                                Anyconnect Premium

Does not support CSD                                                                                   Does support CSD

Does not support Clientless SSL                                                           Does support Clientless SSL

Only supports AnyConnect client connections          Supports all flavours of SSL VPN, including:clientless SSL VPN, AnyConnect client VPN

The OS of the ASA has a software switch in the VPN config that only allows for the ASA to be in one scheme or the other at any one time so you cannot have both and Essentials and Premium license active at the same time.

Re: 2 VPN licences on ASA 5520?

As Julio said, only one of the licenses can be active. If you only need 10 clientless sessions and many AnyConnect-sessions without hostscan or CSD, then it could be cheaper to buy another ASA just for the clientless VPNs and install the Essentials on your actual ASA.
