Cisco Cisco IPS 4255 Sensor

The minimum required version for upgrading to 6.1(3)E3 is 5.0(1) or later, which is available as a 
download from Cisco.com. Use the show version command in the CLI to verify your sensor version 
or view it in IDM or IME.

Use the IPS-AIM-K9-6.1-3-E3.pkg upgrade file to upgrade the AIM IPS and the 
IPS-NME-K9-6.1-3-E3.pkg upgrade file to upgrade the NME IPS. For all other supported sensors, 
use the IPS-K9-6.1-3-E3.pkg upgrade file.

If you configured Auto Update for your sensor, copy the Cisco IPS 6.1(3)E3 update to the directory 
on the server that your sensor polls for updates. 

After installing IPS 6.1(3)E3, you must reboot the sensor.

You cannot uninstall IPS 6.1(3)E3. You must reimagine the sensor using a system image file. All 
configuration settings are lost. 

If you are using automatic update with a mixture of the AIM IPS, NME IPS, and other IPS 
appliances or modules, make sure you put both the 6.1(3)E3 upgrade file (IPS-K9-6.1-3-E3.pkg), 
the AIM IPS upgrade file (IPS-AIM-K9-6.1-3-E3.pkg), and the NME IPS upgrade file 
(IPS-NME-K9-6.1-3-E3.pkg) on the automatic update server so that the AIM IPS and NME IPS can 
correctly detect which file needs to be automatically downloaded and installed. If you only put the 
6.1(2) E3 upgrade file (IPS-K9-6.1-3-E3.pkg) on the server, the AIM IPS and NME IPS will 
download and try to install the wrong file.

When you install the system image for your sensor, all accounts are removed and the default account 
and password are reset to cisco.

You must have a valid Cisco Service for IPS Maintenance contract per sensor to receive and use 
software upgrades from Cisco.com.

When you upgrade the AIM IPS and NME IPS using automatic upgrade, you must disable heartbeat 
reset on the router before placing the upgrade file on your automatic update server. After the 
AIM IPS and NME IPS have been automatically updated, you can reenable heartbeat reset. If you 
do not disable heartbeat reset, the upgrade can fail and leave the AIM IPS and NME IPS in an 
unknown state, which can require a system reimage to recover. 

If you install an update on your sensor and the sensor is unusable after it reboots, you must reimage 
your sensor. 

After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest 
software features.
