Release Notes for Cisco IOS Release 12.3(4)XG on the Cisco ICS 7750
April, 2004
These release notes describe features and functionality of Cisco IOS Release 12.3(4)XG on the Cisco Integrated Communications System (ICS) 7750.
CautionSoftware upgrades for the Cisco ICS 7750 are delivered in packaged system software bundles that are distributed on Cisco.com and/or on CD-ROM. Each Cisco ICS 7750 system software bundle is certified with a specific Cisco IOS release. Appropriate consideration must be given to the other software in the bundle when installing Cisco IOS software in the Cisco ICS 7750. Contact your sales representative for ordering instructions.
These release notes are updated as needed to describe new memory requirements, new features, new hardware support, software platform deferrals, microcode changes, related document changes, and any other important changes. Use these release notes with the Cross-Platform Release Notes for Cisco IOS Release 12.3 located on Cisco.com and the Documentation CD-ROM.

2 Flash memory is not used for the Cisco IOS image on ASIs and MRP200s. Since onboard flash is not available on ASIs and MRP200s, a Cisco IOS compressed image resides on the system processing engine (SPE) and is downloaded to the RAM of each ASI or MRP200 before image decompression.
3 You can upgrade ASI or MRP card memory to 80 MB, 96 MB, or 128MB by installing a dual in-line memory module (DIMM) in the card DIMM slot. For memory upgrade instructions, refer to Installing Memory, PVDM, and VPN Modules in ASI Cards, MRP Cards, and SPE Cards in the Cisco ICS 7750.
4 This image comprises one of the voice-only packages, and does not include data networking support.
Hardware Supported
Cisco IOS Release 12.3(4)XG supports ASIs and MRPs in a Cisco ICS 7750. See Table 2 for a description of the processor cards which are supported in the Cisco ICS 7750.
Processor Cards

Determining Your Software Release
Complete the following steps to determine the Cisco IOS software version running on Cisco ICS 7750 ASI, MRP, or SSP cards:
Step 1
Step 2
telnet IP addressStep 3
Step 4
card> show versionThe following is some of the output that is displayed after entering the command show version on an ASI or MRP card:
router> show versionCisco Internetwork Operating System SoftwareIOS (tm) ICS7700 Software (ICS7700-SV3Y-M), Version 12.3(2)XE, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)Additional output lines from the show version command include information such as the processor revision numbers, amount of available memory, hardware IDs, and partition information.
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features. Cisco IOS Release 12.3(4)XG supports the same feature sets as Releases 12.2 and 12.2T, but Release 12.3(4)XG can include new features supported by the Cisco ICS 7750 platform. Table 7 lists the feature sets supported by the Cisco ICS 7750.

Note
New and Changed Information
There are no new hardware or software features for the Cisco ICS 7750 on Cisco IOS Release 12.3(4)XG.
Important Notes
The following sections contain important notes about Cisco IOS-related issues that can apply to the Cisco ICS 7750.
Software Images on MRP and ASI Cards
All of the MRPs and ASIs in a Cisco ICS 7750 must run the same Cisco IOS image.
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 Release 12.2 T are also in Release 12.3(4)XG. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are located on CCO.

Open Caveats - Release 12.3(4)XG
This section describes unexpected behavior in Release 12.3(4)XG.
CSCec88384
Symptom
MGCP BRI has one-way voice only. This problem does not occur with BRI under H.323.
Workaround
Use BRI under H.323.
CSCed27956
Symptom
TCP checks should verify ACK sequence number.
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.
Workaround
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.

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
