Cisco Cisco IPS 4255 Sensor

The following restrictions and limitations apply to Cisco IME 7.1.1:

You can use IME to monitor sensors running Cisco IPS 5.0 and later; however, some of the new 
features and functionality in IME are only supported on sensors running IPS 6.1 or later.

IME 7.1.1 does not support Cisco IPS 4.x or 3.x sensors.

You can install IME 7.1.1 over all versions of IME but not over IEV. All alert database and user 
settings are preserved.

IME 7.1.1 detects previous versions of IEV and prompts you to manually remove the older version 
before installing IME 7.1.1 or to install IME on another system. The installation program then stops.

Make sure you close any open instances of IME before upgrading to IME 7.1.1. 

If you are using Windows 7 or Windows Server 2008, uninstall any earlier version of IME 
before upgrading to IME 7.1.1. Otherwise, just upgrade from your current IME version to 
IME 7.1.1.

Disable any anti-virus or host-based intrusion detection software before beginning the installation, 
and close any open applications. The installer spawns a command shell application that may trigger 
your host-based detection software, which causes the installation to fail. 

You must be administrator to install IME.

IME 7.1.1 coexists with other instances of the MySQL database. If you have a MySQL database 
installed on your system, you do NOT have to uninstall it before installing IME 7.1.1.

For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no 
password cisco command, but you cannot remove it. To use the no password cisco command, there 
must be another administrator account on the sensor. Removing the cisco account through the 
service account is not supported. If you remove the cisco account through the service account, the 
sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system 
image.

IME launches MySDN from the last browser window you opened, which is the default setting for 
Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet Options, 
and then click the Advanced tab. Scroll down and uncheck the Reuse windows for launching 
shortcuts check box.
