Feature Set Tables
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 included in a release. Each feature set contains a specific set of Cisco IOS features.
Caution
The feature set tables have been removed from the Cisco IOS Release 12.4 release notes to improve the usability of the release notes documentation. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

New Software Features in Cisco IOS Release 12.4(11)XJ2
The following new software features are supported in this release.
•
USB eToken 64KB smartcard support
The Cisco universal serial bus (USB) eToken 64KB smartcard support feature enables device authentication and simplifies the deployment and secure configuration of Cisco routers. It uses smart card technology in a USB form factor to facilitate the authentication and configuration process. The token provides secure access to the route. The token and a PIN are necessary to access the configuration, keys, and credentials.
Some Cisco access router models have USB ports that can be used with Cisco USB flash memory modules or with the Aladdin USB eToken Pro key. These USB modules can be used with a supported Cisco access router for the following functions:
•
•
USB Boot Feature
The USB Boot feature supports booting from ROMMON and IOS. Platforms can boot from USB in ROM monitor with or without a compact flash device. It is not necessary to use a bootloader image from the compact flash device. Partitions, such as usbflash0:2:image_name, are not supported on USB flash drives.
New Hardware Features in Cisco IOS Release 12.4(11)XJ
The following new hardware feature is supported in this release:
•
HWIC and VLAN Feature Enhancements
The Cisco Fast Ethernet HWICs are single-wide interface cards, available as a 1-port HWIC (HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services routers with additional line-rate Layer 3 routed ports. The following enhancements have been made in Cisco IOS Release 12.4(11)XJ:
•

New Software Features in Cisco IOS Release 12.4(11)XJ
The following new software features are supported in this release:
•
ADSL2/2+ Annex M Support
The asymmetric digital subscriber line (ADSL) 2/2+ Annex M feature supports routed bridge encapsulation over VC bundles on specific platforms in Cisco IOS Release 12.4(11)XJ. (ADSL) 2/2+ Annex M supports an upstream data rate of up to 3 Mbps and a downstream data rate of up to 24 Mbps. The increase of the Annex M (upstream) data rate is achieved by using some of the tones that were previously used in the downstream data rate in Annex A. As a result, downstream data rates are decreased in Annex M.
The ADSL training log generation command, dsl-enable-training-log, has been enhanced to specify the time when to capture a log file. This enables the training log to record firmware debug messages.
HWIC-4SHDSL and HWIC-2SHDSL Support
The G.SHDSL HWICs support up to four pairs of digital subscriber lines (DSL): two inverse multiplexing over ATM (IMA) lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.
•
•
Wireless LAN Features
The following features are supported on the wireless LAN (WLAN).
Access Point Link Role Flexibility
Access Point Link Role Flexibility allows access point radios to operate in a combination of radio roles, such as access point root, bridge root (with or without clients), bridge nonroot (with or without clients). This provides a more flexible deployment scheme to support the various applications requirement. Note that the ISR AP does not support access point repeater and WGB.
Advanced Encryption Standard (AES) - CCMP
This feature supports Wi-Fi Protected Access (WPA2) which is the Wi-Fi Alliance specification for interoperable wireless LAN security that supports IEEE 802.11i authentication and AES-CCMP encryption.
Extensible Authentication Protocol
Extensible Authentication Protocol (EAP) is an authentication protocol for the 802.1X framework for mutual authentication between the client and a RADIUS server. New EAP authentication types supported in this IOS release include EAP-TTLS, EAP-MD5, and EAP-SIM.
IEEE 802.1X Local Authentication Service for EAP-FAST
This feature allows an IEEE 802.1X enabled RADIUS Server supporting EAP-FAST authentication types to run on Cisco IOS Software, thereby allowing the access point to authenticate wireless clients when the WAN link is down or the RADIUS Server at the central site is not available.
Microsoft WPS IE SSIDL
SSIDL Information Element support.
Multiple Basic Service Set ID (BSSID)
This feature permits a single AP to appear to the WLAN as multiple virtual APs. It does this by assigning an AP with multiple Basic Service Set IDs (BSSIDs) or MAC address. The AP is able to use a different BSSID to advertise each SSID and is therefore able to appear to WLAN clients as if there are multiple physical APs. Each BSSID/SSID combination advertised by the AP is able to be configured to support encrypted or unencrypted traffic.
NAC - L2 IEEE 802.1x
Network Admission Control (NAC) L2 IEEE 802.1x extends NAC support to layer 2 switches and wireless access points. Combining it with 802.1x provides a unified authentication and posture validation mechanism at the layer 2 network edge. This helps protect the network from attack by machines with insufficient antivirus posture. Performing posture validation at the edge maximizes the portion of the network which is protected and allows posture validation to be performed within a VLAN.
Universal Client Mode
This feature allows the access point radio to act as a client to another Cisco or Third-party access point. See caveats for known issues.
VLAN Assignment By Name
This feature provides the ability for the RADIUS server to assign an 802.11 client to a VLAN identified by NAME. Prior to the introduction of this feature, VLANs had to be identified by "VLAN_ID."
Wi-Fi Multimedia (WMM) Required Elements
This feature supports WMM which is the Wi-Fi Alliance specification for QOS.
Wireless Non-Root Bridge
The wireless non-root bridge allows the access point radio to operate as the remote node in a point to point or point to multi-point network. See caveats for information on antenna support.
Wireless Root Bridge
The wireless root bridge role provides support for both point-to-point or point to multi-point bridging. See caveats for information on antenna support.
New Features in Release 12.4T
For information regarding the features supported in Cisco IOS Release 12.4T, see the Cross-Platform Release Notes and New Feature Documentation links at the following location on Cisco.com:
http://www.cisco.com/en/US/products/ps6441/prod_release_notes_list.html
Caveats
Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
Caveats in Cisco IOS Release 12.4(4)T are also in Cisco IOS Release 12.4(11)XJ. For information on caveats in Cisco IOS Release 12.4T, see the Caveats for Cisco IOS Release 12.4(4)T document. This document lists severity 1 and 2 caveats; the documents are located on Cisco.com.

For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability.

Workaround
CSCsi67763 memory leak under simpleudpfuzz attack for port 500Symptom The U.S. Computer Emergency Response Team (US-CERT) has reported a network evasion technique using full-width and half-width unicode characters that affects several Cisco products. The US-CERT advisory is available at the following link: http://www.kb.cert.org/vuls/id/739224.
By encoding attacks using a full-width or half-width unicode character set, an attacker can exploit this vulnerability to evade detection by an Intrusion Prevention System (IPS) or firewall. This may allow the attacker to covertly scan and attack systems normally protected by an IPS or firewall.

CSCsi65535 codec configured under ephone is used by all monitored phone.Symptom The "codec" configuration under a "ephone" which monitors a line ("ephone-dn") with the "m" button configuration command affects the codec of calls involving that "ephone-dn" as if the line was shared in the regular manner (using the ":" button configuration command).
Conditions
under "ephone" is for SCCP phones registering over a WAN to the CME router. It directs CME to attempt to use the G.729 codec to save some bandwidth over that WAN segment, in SOME (non-VoIP) call scenarios. It doesn't restrict the codec of any call in any way. There is no well defined "negotiation" mechanism that makes use of this codec configuration as in H.323/H.245 codec negotiation for example.Workaround

For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability.

CSCsg17289 DNS-SRV issues for SIP registrationsSymptom Registrar, both the dial-peers would try to send a REGISTER request sequentially. When first Dial-peer (D1) is sending REGISTER Request, the registrar cache is empty. It first sends a DNS query (SRV). After getting the DNS Response, it updates the Registrar cache and sends the REGISTER request to Registrar R1. dns_count variable here is set to SIP_DNS_MODE.
When second dial-peer is sending REGISTER request, it finds the resolved IP address in registrar cache (R1) so it sends the REGISTER request to R1. dns_count variable here is set to SIP_NON_DNS_MODE. But both the REGISTER request fails as R1 is down.
As D1 is set to SIP_DNS_MODE, D1 would send a DNS query again with incremented dns_count to get any alternate Registrar and it gets R2. It sends REGISTER request to R2 and gets successfully registered. As D2 is set to SIP_NON_DNS_MODE, it does not retry the DNS query and simply backs off for period REG_EXPIRES/20.
