New Hardware Features in Release 12.4(2)XA and 12.4(2)XA1
Single Port G.SHDSL WAN Interface Card (WIC-1SHDSL-V3)
A single port multi line G.SHDSL WAN interface card (WIC), or WIC-1SHDSL-V3, provides Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature support for Two-Wire Mode and Four-Wire Mode for SHDSL on the Cisco 1700 series, Cisco 1800 series, Cisco 26xxXM, Cisco 2691, Cisco 2800, Cisco 3700 series, and Cisco 3800 series modular access routers. The WIC-1SHDSL-V3 incorporates the latest firmware and the latest circuitry. For more information about this feature, see the following document:

New Software Features in Release 12.4(2)XA and 12.4(2)XA1
The following sections describe the new software features supported by the Cisco 2600XM series routers for Release 12.4(2)XA.
ATM Oversubscription for DSL
The ATM Oversubscription for DSL feature lets you configure bandwidth oversubscription on Cisco xDSL interfaces up to a defined bandwidth. You can configure variable bit rate (VBR) and unspecified bit rate plus (UBR+) service classes for permanent virtual circuit (PVC) connections with a sum of sustainable cell rates (SCRs) greater than the line rate, which means you can configure an infinite oversubscription amount of bandwidth. Each PVC receives up to its configured SCR value of traffic, and PVCs with higher SCR values receive more bandwidth.
To enable ATM oversubscription for DSL, use the ATM oversubscribe factor command in ATM configuration mode. To disable ATM oversubscription for DSL, use the no form of this command.
atm oversubscribe factor factor
no atm oversubscribe factor factorTo configure unspecified bit rate (UBR) quality of service (QoS) and specify the output peak cell rate and output minimum guaranteed cell rate for an ATM PVC, PVC range, switched virtual circuit (SVC), virtual circuit (VC) class, or VC bundle member, use the ubr+ command in the appropriate command mode. To remove the UBR+ parameters, use the no form of this command.
ubr+ output-pcr output-mcr [input-pcr] [input-mcr]
no ubr+ output-pcr output-mcr [input-pcr] [input-mcr]Multiqueue Command
The multiqueue command enables a priority and a regular (nonpriority) queue for traffic streams. When the command is enabled and there are multiple classes of packet streams over the same PVC, packets coming from the streams that have priority values configured in a policy map are sent to the high priority queue. Packets from all other streams will be sent over the low priority queue. Multiqueue is intended for configuring DSL lines and permits configuring one data flow in a priority queue. If you have configured more than one flow in a priority queue, the latency for delay-sensitive traffic flow may not be guaranteed.
The multiqueue approach does not work well with applications such as MLPPP with interleave and Crypto. This is because MLPPP uses the same sequence numbering scheme for interleaved packets as the multiqueue approach. For example, if there are a voice and two data packets interleaved, the MLPPP sequence numbers for these packets could be 1 for the first data packet, 2 for the voice packet, and 3 for a second data packet. In the multiqueue approach, the voice packet with MLPPP sequence number 2 would go out before the data packet with MLPPP sequence number 1. This would result in out-of-order sequencing of packets as far as MLPPP is concerned, and result in unexpected behavior. The same problems apply to the Crypto application. The multiqueue approach is disabled by default so that when MLPPP and the Crypto applications are used with DSL the network will not be disrupted by upgrading to an image with multiqueue support.
To enable two queues to prioritize multiple classes of packet streams over the same PVC, use the multiqueue command in either the PVC- or VC-class configuration modes. To return to a single queue, use the no form of this command.

Limitations and Restrictions
There are no known limitations or restrictions.
Caveats
Caveats describe unexpected behavior or defects in the 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(2)T are also in Cisco IOS Release 12.4(2)XA. For information on caveats in Cisco IOS Release 12.4(2)T, refer to the Caveats for Cisco IOS Release 12.4(2)T document. This document lists severity 1 and 2 caveats; the documents are located on Cisco.com and the Documentation CD.

Symptoms: The default route is removed if the one of multiple PPPoE session down.
Conditions: This problem occurs when you configure multiple PPPoE which connect to the same BRAS or same LNS if using L2TP and ppp ipcp route default is configured using Cisco IOS Software Release 12.4(2)T1.
Workaround: There is no workaround. However, you can still turn routing on. For example, configure the multiple default routes pointing to the dialer interface(s) as the next hop.

Symptoms: This caveat fix enhances the x25 idle and x25 map interface configuration mode commands to support seconds granularity for X.25 idle VC timeout for X.25 encapsulation VCs.

Workaround: There is no workaround.
•
Symptoms: A PPPoE client router does not honor the ip mtu command settings whey they are configured on the PPPoE dialer interface when the IP MTU is different from the interface MTU.
Fragmentation of IP packets larger than the configured IP MTU will not happen, which can create problems in a PPPoE environment.
Conditions: This symptom occurs whenever a v-access is cloned from the dialer interface and could be PPPoE, multilink or PPPoA.
Workaround: Configure the interface mtu command to the required value.

There are no open caveats in this release.
Resolved Caveats - Release 12.4(2)XA
This section documents possible unexpected behavior by Cisco IOS Release 12.4(2)XA and describes only severity 1 and 2 caveats and selected severity 3 caveats.
•
A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been discovered by an external researcher. The successful exploitation enables an adversary to reset any established TCP connection in a much shorter time than was previously discussed publicly. Depending on the application, the connection may get automatically re-established. In other cases, a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated connection which must be considered. This attack vector is only applicable to the sessions which are terminating on a device (such as a router, switch, or computer) and not to the sessions that are only passing through the device (for example, transit traffic that is being routed by a router). In addition, this attack vector does not directly compromise data integrity or confidentiality.
All Cisco products which contain TCP stack are susceptible to this vulnerability.
This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-ios.shtml, and it describes this vulnerability as it applies to Cisco products that run Cisco IOS® software.
A companion advisory that describes this vulnerability for products that do not run Cisco IOS software is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-nonios.shtml.
Open Caveats - Release 12.4(2)XA
•
Symptoms: The topology change trap is not generated while state from listening to learning & learning to forwarding is getting change on an interface. The new root trap is not generated while bridging is enabled & disabled on interfaces and while changing the mac address to make a new root.
Workaround: There is no workaround.
