Chapter 1 Introduction to the Cisco ASA
ASDM Client Operating System and Browser Requirements
Table 1-1 lists the supported and recommended client operating systems and Java for ASDM.
See the following caveats:
• If you upgrade from a previous version to Java 7 update 5, you may not be able to open ASDM using
the Java Web Start from an IPv6 address; you can either download the ASDM Launcher, or follow
the instructions at: http://java.com/en/download/help/clearcache_upgrade.xml.
• ASDM requires you to make an SSL connection to the ASA in the following situations:
–
When you first connect your browser to the ASA and access the ASDM splash screen.
–
When you launch ASDM using the launcher or the Java web start application.
If the ASA only has the base encryption license (DES), and therefore has weak encryption ciphers
for the SSL connection, you may not be able to access the splash screen or launch ASDM. See the
following issues:
–
When using Java 7 when launching ASDM, you must have the strong encryption license
(3DES/AES) on the ASA. With only the base encryption license (DES), you cannot launch
ASDM. Even if you can connect with a browser to the ASDM splash screen and download the
launcher or web start application, you cannot then launch ASDM. You must uninstall Java 7,
and install Java 6.
–
When using Java 6 for accessing the splash screen in a browser, by default, Internet Explorer on
Windows Vista and later and Firefox on all operating systems do not support DES for SSL;
therefore without the strong encryption license (3DES/AES), see the following workarounds:
