C H A P T E R 2Feature Support

Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms.The feature sets available for a specific platform depend on which Cisco IOS software images are includedin a release. Each feature set contains specific Cisco IOS features.

Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data encryptionfeature sets) are subject to U.S. government export controls and have limited distribution. Strong encryptionimages to be installed outside the United States are likely to require an export license. Customer ordersmay be denied or subject to delay because of U.S. government regulations. When applicable, thepurchaser/user must obtain local import and use authorizations for all encryption strengths. Please contactyour sales representative or distributor for more information, or send an e-mail to [email protected].

Cisco Feature Navigator is a web-basedtool that enables you to determine which Cisco IOS software images support a specific set of features andwhich features are supported in a specific Cisco IOS image. You can search by feature or by feature set(software image). You can compare Cisco IOS software releases side-by-side to display both the featuresunique to each software release and the features that the releases have in common.

Determining the Software Images (Feature Sets) That Supporta Specific Feature

To determine which software images (feature sets) in a Cisco IOS release support a specific feature, go to theCisco Feature Navigator home page and perform the following steps.

SUMMARY STEPS

1. From the Cisco Feature Navigator home page, click Research Features.2. Select your software type or leave the field as “All”.3. To find a feature, you can search by either Feature or Technology (select the appropriate button). If you

select Search by Feature, you can further filter your search by using the Filter By text box.4. Choose a feature from the Available Features text box, and click the Add button to add the feature to the

Selected Features text box.5. Click Continue when you are finished choosing features.6. In the Release/Platform Tree area, select either your release (from the Train-Release list) or your platform

(from the Platform list).7. The “Search Result” table will list all the software images (feature sets) that support the features that you

chose.

ISM Restartability

When the ISM-VPNmodule is disabled because of a crash, the router’s encryption and decryption performancedegrade due to the usage of an onboard crypto-engine. The ISM Restartability feature allows you to rebootthe module so that the ISM-VPNmodule can register again as a new crypto engine and download the relevantpolicies required to handle the crypto load of the router.

The ISM Module can be rebooted 3 times in an hour. However, if there are more than three crashes in lessthan an hour, the ISM-VPN module is not rebooted. You must reset the timers and enable the ISM-VPNmodule using the crypto engine slot and crypto engine accelerator command.

Important NotesThe following sections contain important notes about Cisco IOS Release 15.4M&T:

Field Notices and Bulletins• Field Notices—Cisco recommends that you view the field notices for this release to see if your softwareor hardware platforms are affected. You can find field notices at http://www.cisco.com/en/US/support/tsd_products_field_notice_summary.html

• Bulletins—You can find bulletins at http://www.cisco.com/c/en/us/products/ios-nx-os-software/ios-software-releases-listing.html

Change in the Default Value for the transport input CommandPrevious to Cisco IOSRelease 15.4(3)M4, the default was the transport input all command. If you are upgradingto a release later than Cisco IOS Release 15.4(3)M4, you must configure the transport input none command,or you will be locked out of your device.

Session Initiation Protocol (SIP) or Application-Layer Gateway (ALG) Feature SetIf you are using Cisco IOS Software 15.4(3)M6a with a default configuration, the Session Initiation Protocol(SIP) or Application-Layer Gateway (ALG) feature set in Cisco Software could allow an unauthenticatedremote attacker to initiate unwanted SIP connections to an affected appliance. The SIP connections are initiateddue to improper input verification mechanisms in the system. An attacker could connect via unused portsduring Port-Address Translation (PAT) operations, thereby conducting unwanted reconnaissance or gainingaccess to sensitive information.

Logging into the Embedded AP and Etherswitch ModulesStarting from Cisco IOS Release 15.4(03)M08, you have to configure 'transport input all' under the 'line config'to log in to the embedded AP and Etherswitch modules.

Open Plug-N-Play Agent

The Open Plug-N-Play Agent is a software module running on an IOS device. This feature enables theacquisition and loading of pertinent image, configuration, and other required files to the device along withnotifications for various events.

In the absence of a startup configuration file, the Open Plug-n-Play agent attempts to discover the address ofthe Open Plug-n-Play server. For this the Open Plug-n-Play agent uses DHCP, Domain Name System (DNS)server and other methods to acquire the desired IP address of the PnP server.

Retain DSCP Setting of RTP Packet

This feature introduces the preserving and forwarding of Differentiated services code point (DSCP) markingsreceived from endpoints by Cisco Unified Communications Manager (CUCM) when the programmed valuefrom CUCM is NULL.

Media Termination Point (MTP) does not store the DSCP for a session, but picks the value from an incomingpacket and inserts it into an outgoing packet. Thus DSCP value from an endpoint can change in the middleof a session.
