Upgrading Cisco NAC Appliance Software
Note
This Installation Guide does not cover the Cisco NAC Network Module (NME-NAC-K9). For
information on Cisco NAC Network Module installation and configuration, see
Getting Started with
Cisco NAC Network Modules in Cisco Access Routers .
Cisco NAC Appliance CAMs/CASs are preloaded with a default version of the Cisco NAC Appliance
software, which may not match the latest release image. Cisco recommends you always run the latest
supported version of the system software to ensure you have the latest product enhancements and fixes.
You can install Cisco NAC Appliance Release 4.8(x) only on the following Cisco NAC Appliance
platforms:
•
NAC-3315, NAC-3355, and NAC-3395
• NAC-3310, NAC-3350, and NAC-3390
•
Cisco NAC Network Module (NME-NAC-K9)
In addition to the above, you can install Cisco NAC Appliance Release 4.8 on CCA-3140 (EOL).
Note
Due to limited hardware resources on the CCA-3140, some combinations of Release 4.8 features may
cause undesirable system behavior. If you are experiencing problems with Release 4.8 on the CCA-3140,
please contact the Cisco Technical Assistance Center (TAC).
Note
The support for CCA-3140 has been dropped starting from Cisco NAC Appliance release 4.8(1).
Upgrading to Release 4.8(x)
In Cisco NAC Appliance release 4.8(x), you use a .tar.gz upgrade process similar to that used for
upgrading CAM/CAS appliances in Cisco NAC Appliance Release 4.7(2) and 4.6(1). (Cisco NAC
Appliance release 4.7(0) and 4.7(1) requires users to perform “in-place” upgrades via an .ISO image on
a CD-ROM.)
To upgrade to Release 4.8(x), follow the appropriate upgrade instructions in the “Upgrading” section of
the
Release Notes for Cisco NAC Appliance corresponding to your latest Cisco NAC Appliance release
version.
Note You cannot use the Release 4.8(x) .ISO CD-ROM to perform an upgrade. You must use the .tar.gz
upgrade file method.
Note
You must upgrade the CAM first prior to upgrading the CAS. Otherwise, you will end up in a situation
in which CAS has been upgraded but not the CAM.
