Product Bulletin No. 3514
PRODUCT OVERVIEW
This product bulletin provides content and delivery information for Cisco IOS® Software Special Release 12.4(6)XE. It should be used in conjunction with the release notes for Cisco IOS Software Release 12.4T at http://www.cisco.com/en/US/products/ps6824/index.html, because 12.4(6)T is the parent release of 12.4(6)XE.
This product bulletin lists only the features in Cisco IOS Software Release 12.4(6)XE (see Table 1) that are new to the respective routers; more information is available in the release at http://www.cisco.com/en/US/products/ps6441/prod_release_notes_list.html. Customers should be prepared to upgrade using the migration path described in the "Upgrade Paths" section.

NEW FEATURES
Cisco Cable Modem High-Speed WAN Interface Cards
• Provide quality of service (QoS) upstream flow control, integrating DOCSIS QoS with Cisco IOS Software QoS and packet cable multimedia (PCMM) architecture QoS with Cisco IOS Software QoS.
• Use Cisco IOS Software to deliver advanced network services and applications.
• Support compression and decompression algorithms (codecs).
Mobile IP Support for NAT Traversal
The Mobile IP Support for RFC3519 NAT Traversal on Cisco 3200 Series Wireless and Mobile Routers feature extends support for NAT traversal to the mobile router in the scenario in which there is no foreign agent and the mobile router needs to register to the home agent directly using a private CCOA.
NAT traversal is based on the RFC3519 specification and defines how mobile IP should operate to traverse networks that deploy NAT within their network. NAT traversal allows mobile IP to interoperate with networks that have NAT enabled by providing an alternative method for tunneling mobile IP data traffic. New extensions in the mobile IP registration request and reply messages have been added that establish User Datagram Protocol (UDP) tunneling.

Modified CLI Command
The service declassify command has been modified with this release.
To enable the declassification function to monitor the trigger signals from the declassification trigger, use the service declassify command in global configuration mode. To disable the declassification function, use the no form of this command.
service declassify [ erase-default |erase-flash | erase-nvram | erase-all] [trigger AUX | GPIO]
no service declassify [ erase-default |erase-flash | erase-nvram | erase-all] [trigger AUX | GPIO]
The following options were added to the service declassify command:
· trigger, AUX, and GPIO (General Purpose Input Output)
- The trigger option enables the declassification trigger source.
- The AUX option enables the declassification trigger on the AUX port CTS pin. This is the default trigger source.
- The GPIO option enables the declassification trigger on the actuator.
The trigger option is supported on customized Cisco 3270 router boards only. The system integrator needs to install a special cable or actuator so the GPIO trigger source can be used on the customized boards. For Cisco 3270 routers with standard enclosures, the trigger option does not need to be configured.
After declassification is enabled and the AUX port is selected as the trigger source, the Aux port on the router should not be used for any other functions, or the router might receive false trigger signals. On certain customized Cisco 3270 routers, you can enable declassification and select the special actuator connecting the GPIO port as the trigger source. In this case, the AUX port can still be used for regular data functions.
UPGRADE PATHS
CISCO IOS Software Special Release 12.4(6)XE is a short-lived release. It is based on the third release of 12.4T: Release 12.4(6)T. It will migrate into the sixth release of 12.4T. Customers should be prepared to migrate to the sixth release of 12.4T when it is available.
AVAILABILITY
Cisco IOS Software Special Release 12.4(6)XE is targeted for June 26, 2006.
