Prerequisites for GET VPN Support of IPsec Inline Tagging for Cisco TrustSec
All key servers (KSs) and group members (GMs) on which you want to enable this feature must be running GET VPN software version 1.0.5 or higher. You should use this feature only after all devices in the GET VPN network are upgraded to GET VPN software versions that support it.
This feature provides a command that you use on the KS (or primary KS) to check whether all devices in the network are running versions that support IPsec inline tagging for Cisco TrustSec. For more information, see the "Ensuring That GMs Are Running Software Versions That Support IPsec Inline Tagging for Cisco TrustSec" section.
