Version 4.1.1 was posted to CCO for download on April 30th.
Some of the feature "enhancements" that i found interesting and useful, but not too geeky are:
- Support for Windows Vista
This works in conjunction with a Virtual Gateway CAS using VLAN Mapping to ensure that only known VLAN ID packets are allowed to traverse the internal network. This should prevent any broadcast/loop issues that might have previously happened.
- WSUS Support
Now we are playing ball with the introduction of WSUS support. This release tightly integrates updates through WSUS, to ensure users have the proper patches.
This is only a few of the many new enhancements in 4.1(1). To review all enhancement, caveats and upgrade procedures please read the following release notes:
Cisco NAC Appliance 4.1(1) Release Notes
Please note that it is best practice to follow the upgrade procedures to the "T" when upgrading a NACA deployment.
For those of you just getting into the land of NACA, there is a very good presentation on the features that came about in Release 4.1(0) located on CCO called "What's New in Cisco NAC Appliance 4.1" that should catch you up on the latest and greatest features.
