Problem Description

The Sun Java Cryptography Extension (JCE) 1.2.1 used in several Cisco products is set to expire at Midnight on July 27th, 2005.

Products using this version of the Java Cryptography Extension will experience issues where key functionality will stop working.


JCE 1.2.1 is at the "End of Service Life" for Sun Microsystems, and is no longer supported.

Additional information regarding the JCE 1.2.1 End of Service Life can be found in the Sun Microsystems Bulletin.

Problem Symptoms

Products affected by this JCE 1.2.1 expiration (After July 27th, 2005) will experience product and feature functionality issues. Product symptoms will include:

Cisco WAN Manager (CWM)

CWM 11.0.10 (both Solaris 7 and Solaris 8) and 12.0 use the Sun JRE 1.3.1 and Java Cryptography Extension (JCE) version 1.2.1 for PC clients to establish a secure connection to the server and launch GUI applications. Since JCE 1.2.1 expires on July 27th, 2005 three applications of CWM (Network Configurator, Network Browser, and CiscoView) can not be launched and used by PC clients. Other applications do not rely on JCE 1.2.1 and can be launched from PC client via Network Topology.

Note: The CWM 11.0.10, 11.0.10 patches, 12.0 and 12.0 patches require the JCE 1.2.2 patch. The JCE 1.2.2 patch must be applied after every new CWM 11.0.10, 11.0.10 patch, 12.0 and 12.0 patch installation.

Later releases of CWM such as 15.0, CWM 15.0 patches and 15.1 use JRE 1.4 which does not have any expiration date. CWM 15.0 and 15.1 use the JRE 1.4.2 features.

Earlier releases of CWM such as 10.4 and 10.5 do not have a PC client option.

CiscoWorks Wireless LAN Solution Engine (CWWLSE)

When the certificate expires, key WLSE functionality such as high availability (HA), Configuration, and AP firmware update jobs will be unavailable until the patch is installed.

Host Solution Engine (HSE)

HSE Customers encountering this issue will receive Error 500 Interrupt Messages and the application will not work.
