AnyConnect SSL VPN with CAC (SmartCard)

Start with a guide to APM Network Access:

https://support.f5.com/kb/en-us/products/big-ip_apm/manuals/product/apm-network-access-11-6-0.html

Then information about the Edge Client (analogous to Cisco's AnyConnect SSL VPN client):

https://support.f5.com/kb/en-us/products/big-ip_apm/manuals/product/apm-client-configuration-11-6-0.html

And specific information about Edge client on different client operating systems can be found at the bottom of the main documentation page.

https://support.f5.com/kb/en-us/products/big-ip_apm/versions.11-6-0.html

I'm listing documentation for 11.6, but similar docs can be found for other versions.
