Symptom: The NAC Agent gets suck in a posture loop. The sequence of events seen for the agent is: 1) An authentication entry is seen for the host and posture is set to pending. 2) A CoA is sent for the host with the posture status matching the globally set default posture status. 3) An authentication is again seen for the host with the posture status set to pending.
Conditions: ISE 126.96.36.1999 An application is installed on the end host that sends an HTTP or HTTPS packet with an unknown user-agent. Posture is configured and in use.

Instructions for Upgrading to Cisco ISE, Release 1.2.1
You can upgrade to Cisco ISE, Release 1.2.1 directly from any of the following releases:
Cisco ISE, Release 188.8.131.525 with patch 5 or later
Cisco ISE, Release 184.108.40.2068 with patch 7 or later
Cisco ISE, Release 1.1.2 with patch 10 or later
Cisco ISE, Release 1.1.3 with patch 11 or later
Cisco ISE, Release 1.1.4 with patch 11 or later
Cisco ISE, Release 220.127.116.119 with patch 8 or later
The process for upgrading to Release 1.2.1 is the same as upgrading to Release 1.2. The system reboots twice when you upgrade from Release 1.1.x to 1.2.1 because it involves a 32-bit to 64-bit system upgrade, but only once when you upgrade from Release 1.2.x to 1.2.1 because Release 1.2 is a 64-bit system.
The application upgrade command is enhanced and includes the cleanup, prepare, and proceed options. You can use:
Cleanup—To clean a previously prepared upgrade bundle on a node locally. You can use this option if:
The application upgrade prepare command was interrupted for some reason
The application upgrade prepare command was run with an incorrect upgrade bundle
The upgrade failed for some reason
Prepare—To download and extract an upgrade bundle locally. You can use this command followed by the application upgrade proceed command.
Proceed—To upgrade Cisco ISE using the upgrade bundle you extracted with the prepare option. You can use this option after preparing an upgrade bundle instead of using the application upgradeise-upgradebundle-1.2-to-1.2.1.xxx.i386.tar.gzremote-repository command.
If upgrade is successful, this option removes the upgrade bundle.
If upgrade fails for any reason, this option retains the upgrade bundle.
