New Hardware Features in Release 12.4(11)SW

There are no new hardware features on the Cisco 2600XM series routers or the Cisco 2800 integrated service routers in Cisco IOS Release 12.4(11)SW.

New Software Features in Release 12.4(11)SW

The following new software features are supported by the Cisco Cisco 2600XM series routers and the Cisco 2800 integrated service routers in Cisco IOS Release 12.4(11)SW:

C-Link Backup Routing of M3UA/SUA Traffic

Cisco IOS Release 12.4(11)SW supports a C-link Backup Routing feature that provides backup routing to MTP3 User Adaptation Layer (M3UA) and SCCP User Adaptation (SUA) application servers (ASs). It uses a Message Transfer Part Level 3 (MTP3)/M2PA linkset to a remote signaling gateway (SG) serving the same ASs over Stream Control Transmission Protocol (SCTP)/IP. This configurable software feature is available to any IP Transfer Point (ITP) running a sigtran protocol (M3UA and/or SUA) and offloaded MTP3. The remote SG that is reachable through the C-link may be another ITP, or any SG serving the same ASs.

GWS SCCP Error Return

Cisco IOS Release 12.4(11)SW allows you to configure Gateway Screening (GWS) to return a unitdata service (UDTS) to the source of the Signaling Connection Control Part (SCCP) packet when the SCCP packet is dropped. You configure a return UDTS when you define the gateway screening action set in enhanced GWS.

MLR SCCP Error Return

Cisco IOS Release 12.4(11)SW allows you to configure Multi Layer Routing (MLR) to return a unitdata service (UDTS) to the source of the Signaling Connection Control Part (SCCP) packet when the SCCP packet is blocked. You configure this by specifying an optional sccp-error parameter on block results in MLR rules and MLR address tables.

Multiple HSL PVCs per Physical ATM interface

Cisco IOS Release 12.4(11)SW allows multiple High Speed Link (HSL) permanent virtual circuits (PVCs) per physical Asynchronous Transfer Mode (ATM) interface. This is done through the support of subinterface configuration on the ATM link. Prior to Cisco IOS Release 12.4(11)SW, you could only configure the ATM interface, not any subinterfaces. The ability to create additional subinterfaces allows for more qssals, since only one qssal is allowed per interface or subinterface.

SCCP/MAP Address Modification for SRI-SM Messages

C-Link Backup Routing of M3UA/SUA Traffic	Yes	See Table 2 for image names.
GWS SCCP Error Return
MLR SCCP Error Return
Multiple HSL PVCs per Physical ATM interface
SCCP/MAP Address Modification for SRI-SM Messages

Cisco IOS Release 12.4(11)SW permits Signaling Connection Control Part (SCCP) and MAP address modification using a Multi-Layer Routing (MLR) modify-profile. MLR currently supports modifying only the service center address (orig-smsc) and the calling party address (CgPA) for SRI-SM messages.

With Cisco IOS Release 12.4(11)SW, the user can also now optionally configure the desired action for failed modifications using the modify-failure command within the MLR options submode. A user can also configure the preserve-opc function within the global MLR options submode. The preserve-opc function retains the original Originating Point Code (OPC). The user may configure MLR to return a unitdata service (UDTS) to the source of the SCCP packet when the SCCP packet is blocked by specifying an optional sccp-error parameter on block results.

Limitations and 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(11)T are also in Cisco IOS Release 12.4(11)SW. For information on caveats in Cisco IOS Release 12.4(11)T, refer to the Caveats for Cisco IOS Release 12.4(11)T document. This document lists severity 1 and 2 caveats; the documents are located on Cisco.com.

Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity. To reach the Bug Toolkit, log in to Cisco.com and click Service & Support: Technical Assistance Center: Tool Index: Bug Toolkit. Another option is to go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl.

Because Cisco IOS Release 12.4(11)SW is the initial base release, there are no resolved caveats. For a list of the resolved caveats, refer to the next set of release notes for this release version.

Open Caveats—Cisco IOS Release 12.4(11)SW

Symptoms: Cisco IP Transfer Point (ITP) running Cisco IOS Release 12.4(11)SW reports the Message Transfer Part Level 3 (MTP3) route as Avail, but the destination is reported as INACC.

Conditions: This issue occurs during a system boot while processing a large route table because the MTP3 restart may not complete before the mtp3 timers expire. As a result, the system may be in an intermediate state where routes are available but the destination is inaccessible.

Resolved Caveats—Cisco IOS Release 12.4(11)SW

A vulnerability has been discovered in a third party cryptographic library which is used by a number of Cisco products. This vulnerability may be triggered when a malformed Abstract Syntax Notation One (ASN.1) object is parsed. Due to the nature of the vulnerability it may be possible, in some cases, to trigger this vulnerability without a valid certificate or valid application-layer credentials (such as a valid username or password).

Successful repeated exploitation of any of these vulnerabilities may lead to a sustained Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow an attacker will not be able to decrypt any previously encrypted information.

Cisco has made free software available to address this vulnerability for affected customers. There are no workarounds available to mitigate the effects of the vulnerability.

Cisco Product Security Overview

A current list of security advisories and notices for Cisco products is available at this URL:

If you prefer to see advisories and notices as they are updated in real time, you can access a Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

Tip

We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you want to obtain customized information and service, you can self-register on Cisco.com. To access Cisco.com, go to this URL:

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

•

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
