New Features
New Features in Version 8.2(5)/6.4(3)
/ASDM Version 6.4(3)
New Features in Version 8.4(1)/6.4(1)
Released: January 31, 2011
Table 1 -6 lists the new features for ASA Version 8.4(1)/ASDM Version 6.4(1).
ASA-Tandberg
Interoperability with H.323
Inspection
H.323 Inspection now supports uni-directional signaling for two-way video sessions. This
enhancement allows H.323 Inspection of one-way video conferences supported by Tandberg
video phones. Supporting uni-directional signaling allows Tandberg phones to switch video
modes (close their side of an H.263 video session and reopen the session using H.264, the
compression standard for high-definition video).
Also available in Version 8.2(5).
Routing Features
Timeout for connections
using a backup static route
When multiple static routes exist to a network with different metrics, the ASA uses the one with
the best metric at the time of connection creation. If a better route becomes available, then this
timeout lets connections be closed so a connection can be reestablished to use the better route.
The default is 0 (the connection never times out). To take advantage of this feature, change the
timeout to a new value.
Also available in Version 8.2(5).

Feature Description
Table1-6 New Features for ASA Version 8.4(1)/ASDM Version 6.4(1)
Feature Description
Hardware Features
Support for the ASA5585-X We introduced support for the ASA 5585-X with Security Services Processor (SSP)-10, -20,
-40, and -60.
Note Support was previously added in 8.2(3) and 8.2(4); the ASA 5585-X is not supported
in 8.3(x).
No Payload Encryption
hardware for export
You can purchase the ASA 5585-X with No Payload Encryption. For export to some countries,
payload encryption cannot be enabled on the Cisco ASA 5500 series. The ASA software senses
a No Payload Encryption model, and disables the following features:
•Unified Communications
•VPN
You can still install the Strong Encryption (3DES/AES) license for use with management
connections. For example, you can use ASDM HTTPS/SSL, SSHv2, Telnet and SNMPv3. You
can also download the dynamic database for the Botnet Traffic Filer (which uses SSL).
