Release Notes for Cisco Intrusion Prevention System 5.1(7)E1

OL-8492-01

After Upgrading to Cisco IPS 5.1(7)E1

Note If you are converting from IPS 4.x, the 4.x configuration has to be converted to the 5.1(7)E1 commands,

because IPS 5.1(7)E1 has some new configuration parameters.

Caution If the configuration is not properly converted, see Caveats, page 33, or check Cisco.com for any upgrade

issues that have been found. Contact the TAC if no DDTS refers to your situation.

SSL Certificate

If necessary import the new SSL certificate for the upgraded sensor in to each tool being used to monitor

the sensor.

For More Information

For the CLI procedure, refer to Configuring TLS, or for the IDM procedure, refer to Configuring

Certificates.

Increasing the Memory Size of the Java Plug-In

To correctly run IDM, your browser must have Java Plug-in 1.4.2 or 1.5 installed. By default the Java

Plug-in allocates 64 MB of memory to IDM. IDM can run out of memory while in use, which can cause

IDM to freeze or display blank screens. Running out of memory can also occur when you click Refresh.

OutofMemoryError message appears in the Java console whenever this occurs. You must change the

memory settings of Java Plug-in before using IDM. The mandatory minimum memory size is 256 MB.

Note We recommend that you use Sun Microsystems Java. Using any other version of Java could cause

problems with IDM.
