Upgrading to Software Version 6.1(x) from a Software Version 
Prior to 5.1(4)
During the upgrade process, the Guard module changes two parameters that may affect your 
configuration. The following information describes the two parameters:
In software versions prior to 6.0(5), the Guard module supported loopback interfaces. In software 
version 6.0(5) or later, the Guard module no longer supports loopback interfaces and deletes all 
loopback interface configurations during the upgrade process.
In software version 4.x, the Guard module allowed you to configure illegal subnet masks. In 
software version 5.1(4), the Guard module checks to ensure that subnet masks are legal. When you 
upgrade from a software version prior to 5.1(4) to 6.1(x), the Guard module corrupts all zone 
configurations that contain an illegal subnet mask. To prevent the module from corrupting a zone 
configuration that contains an illegal subnet mask, configure the zone configuration with a legal 
subnet mask by performing the following steps before upgrading the software:
1.
Use the no ip address command to delete the subnet mask.
2.
Use the ip address command to configure the subnet mask with a legal subnet.
For details on configuring zone IP addresses, see the “Configuring the Zone IP address Range” 
section in the Cisco Anomaly Guard Module Configuration Guide. Software upgrade instructions 
are located in the “Upgrading the Guard Module Software” section in the Cisco Anomaly Guard 
Module Configuration Guide
