Cisco Cisco NAC Appliance 4.8.3 Release Notes

In Cisco NAC Appliance release 4.8(3), you can use a .tar.gz upgrade process similar to that used for 
upgrading CAM/CAS appliances in earlier releases of Cisco NAC Appliance (like the process used in 
Release 4.6(1), 4.7(2), and 4.8) instead of having to perform “in-place” upgrades via an .ISO image on 
a CD-ROM, as is required to upgrade to Cisco NAC Appliance release 4.7(0) and 4.7(1). For more 
information, see 

You cannot use the Release 4.8(3) .ISO CD-ROM to perform an upgrade. You must use the .tar.gz 
upgrade file method.

In Cisco NAC Appliance Release 4.8(3), support for Mac OS X 10.4 has been removed. 

If you are using a client machine with Mac OS X 10.4, you need to upgrade it to Mac OS X 10.5 or later 
to work with Cisco Mac OS X Agent 4.8.3.594.

See 

 for the latest AV/AS product charts.

The Cisco NAC Appliance Supported AV/AS Product List is a versioned XML file distributed from a 
centralized update server and downloaded to the Clean Access Manager via Device Management > 
Clean Access > Updates > Update. It provides the most current matrix of supported antivirus (AV) and 
anti-spyware (AS) vendors and products per version of the Agent, and is used to populate AV/AS Rules 
and AV/AS Definition Update requirements for Agents that support posture assessment/remediation.

You can access AV and AS product support information from the CAM web console under Device 
Management > Clean Access > Clean Access Agent > Rules > AV/AS Support Info. For convenience, 
this section also provides the following summary and product charts. The charts list which product 
versions support virus or spyware definition checks and automatic update of client virus/spyware 
definition files via the user clicking the Update button on the Agent.

In some cases, the specific AV/AS vendor software requires the user to have administrator privileges on 
the client machine to enable updates.

For Windows 7/Vista/XP AV/AS support information on the Cisco NAC Agent (version 4.8.3.9) and 
Cisco NAC Web Agent (version 4.8.3.1), see the
