Cisco Cisco IPS 4255 Sensor

Pay attention to the following upgrade notes and caveats when upgrading to IPS 7.1(2)E4:

Anomaly detection has been disabled by default. If you had not configured the operation mode 
manually before the upgrade, it defaults to inactive after you upgrade to IPS 7.1(2)E4. If you 
configured the operation mode to detect, learn, or inactive, the tuned value is preserved after the 
upgrade. 

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

You must have a valid maintenance contract per sensor to download software upgrades from 
Cisco.com.

You must be running IPS 7.1(1)E4 to upgrade to IPS 7.1(2)E4.

This service pack automatically reboots the sensor to apply the changes. During reboot, inline 
network traffic is disrupted. 

If you are running S500-S553 or S555-S559, change signature 23899.0 to the default setting before 
applying the 7.1(2)E4 service pack. 

You cannot uninstall 7.1(2)E4. To revert to a previous version, you must reimage the sensor using 
the system image file.
