Pay attention to the following upgrade notes and caveats when upgrading to IPS 7.1(6)E4:

The default value of the Cisco server IP address has been changed from 198.133.219.25 to 
72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on 
your sensor, you may need to update firewall rules to allow the sensor to connect to this new IP 
address.

If you are upgrading the IPS 4270-20 and you have a license for 6.0.x and earlier, you receive the 
following error message:

Currently installed License is not valid in 7.1(3). Install a license that is 

applicable for IPS versions 6.1 and above.

You must get a new license before upgrading your IPS 4270-20.

Anomaly detection has been disabled by default. If you did not configure the operation mode 
manually before the upgrade, it defaults to inactive after you upgrade to IPS 7.1(6)E4. If you 
configured the operation mode to detect, learn, or inactive, the tuned value is preserved after the 
upgrade. 

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

You must be running the following versions to upgrade the following platforms to IPS 7.1(6)E4:

For the IPS 4200 series sensors, you must be running IPS 6.0(6)E4 or later.

For the IPS 4300 series sensors and the ASA 5500-X IPS SSP series, you must be running 
IPS 7.1(3)E4 or later. 

For the IPS 4500 series sensors, you must be running IPS 7.1(4)E4 or later. 

For the ASA 5500 AIP SSM series, you must be running IPS 6.0(6)E4 or later. 

For the ASA 5585-X IPS SSP series, you must be running IPS 7.1(1)E4 or later. 

A generic upgrade package is no longer available for the IPS 4240, IPS 4255, IPS 4260, and 
ASA 5500 AIP SSM series. These platforms now have platform-specific filenames in accordance 
with the 7.1(x) format. 

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