Cisco IOS Release 12.3(2)XF supports the Cisco 3200 Series Mobile Access Router.
For descriptions of existing hardware features and supported modules, see the configuration guides and additional documents specific to the Cisco 3200 Series Mobile Access Router, which are available on Cisco.com at the following location:
http://www.cisco.com/univercd/cc/td/doc/product/access/mar_3200/index.htm
Determining the Software Version
To determine the version of Cisco IOS software running on your Cisco router, log in to the router and enter the show version EXEC command. The following sample displays command output from a Cisco 3200 series router running Cisco IOS Release 12.3(2)XF:
Cisco Internetwork Operating System Software
IOS (tm) 3200 Software (C3250-ENTBASE-M), Release 12.3(2)XF
Configuration register is 0x0
Upgrading to a New Software Release
You can download either a software image or a configuration file via TFTP or via the console port. After downloading, the file is saved to the Flash memory.
Use console download when you do not have access to a TFTP server.
If you are using a PC to download a Cisco IOS image over the router console port at 115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver (UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 or less when downloading a Cisco IOS image over the console port.
Configure the PC communications port to match the router console port as follows:
•9600 baud
•8 data bits
•no parity
•1 stop bit
Follow the steps below to run Xmodem:
Step 1 Move the image file to the local drive on your PC connected to the router.
Step 2 Enter the xmodem command at the rommon > prompt.
Following is the syntax and descriptions for the xmodem console download command:
xmodem [-ucyrx] destination_file_name
u
|
(Optional) Performs an upgrade of the ROMMON. System reboots after the file is upgraded.
|
c
|
(Optional) Performs the download using 16-bit cyclic redundancy check (CRC-16) error checking to validate packets. Default is 8-bit CRC.
|
y
|
(Optional) Sets the router to perform the download using Ymodem protocol. Default is Xmodem protocol. The protocols differ as follows:
|
•Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block transfer size.
|
•Ymodem uses (CRC)-16 error checking to validate each packet. Depending on the device that the software is being downloaded from, this function might not be supported by Xmodem.
|
r
|
(Optional) Image is loaded into DRAM for execution. Default is to load the image into Flash memory.
|
x
|
(Optional) Image is loaded into DRAM without being executed.
|
destination_file_name
|
The name of the system image file or the system configuration file. In order for the router to recognize it, the name of the configuration file must be in the form of router_confg.
|
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(2)XF supports the same feature sets as Cisco IOS Release 12.3(2)T, but Cisco IOS Release 12.3(2)XF can include new features supported by the Cisco 3200 series router.
Table 2 lists the features and feature sets supported in Cisco IOS Release 12.3(2)XF.
The table uses the following conventions:
•"In" column—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, "12.3(2)XF" indicates that a feature was introduced in 12.3(2)XF. If a cell in this column is empty, the feature was included in a previous release or the initial base release.
•"Platform and Feature Sets" column
–Yes—The feature is supported in the software image.
–No—The feature is not supported in the software image.
Note These feature set tables contain only a list of selected features. These tables are not cumulative—nor do they comprehensively list all the features in each image.

New and Changed Information
The following sections list the new software features supported by the Cisco 3200 Series Mobile Access Router for Cisco IOS Release 12.3(2)XF.
Mobile IP - Mobile Networks Deployment MIB
The Mobile Networks Deployment MIB feature provides MIB support for customers who are deploying Cisco Mobile Networks. Mobile IP management using Simple Network Management Protocol (SNMP) is defined in two MIBs: the RFC2006-MIB and the CISCO-MOBILE-IP-MIB.
This feature is useful for customers deploying mobile networks functionality that need to monitor and debug mobile router information via SNMP.
For more details, refer to the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123t/123t_4/gtmdebug.htm
NetFlow
The NetFlow technology efficiently provides the metering base for a key set of applications including network traffic accounting, usage-based network billing, network planning, as well as denial services monitoring capabilities, network monitoring, outbound marketing, and data mining capabilities for both service provider and enterprise customers. Cisco provides a set of NetFlow applications to collect NetFlow export data, perform data volume reduction, post-processing, and provide easy access to NetFlow data to end user applications. Cisco is currently working with a number of partners to provide customers with comprehensive solutions for NetFlow-based billing, planning and monitoring.

Caveats
Caveats describe unexpected behavior 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 Releases 12.3(2) T are also in Cisco IOS Release 12.3(2)XF. For information on caveats in Cisco IOS Release 12.3T, see Caveats for Cisco IOS Release 12.3(2)T. This document lists severity 1 and 2 caveats and are located on Cisco.com and the Documentation CD-ROM.
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 into 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.
Open Caveats - Cisco IOS Release 12.3(2)XF
This section lists open caveats for Cisco IOS Release 12.3(2)XF. Only severity level 1 through 3 are listed.
CSCin62655
Router crashes on unconfiguring and shutting down the interface.
If a virtual tunnel interface is configured with a serial interface, the MAR might crash and dump buffer content in very rare occasions upon unconfiguring and shutting down the serial interface.

CSCin62122
bufferBgFree object shows 49 instead of 50 initially.
The bufferBgFree object of OLD-CISCO-MEMORY-MIB shows the value as 49 initially instead of 50.
The command-line interface (CLI) shows 50.
CSCec50561
Can not disable the hardware flow control on AUX port.
CSCed27956
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.

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.
Cisco TAC inquiries are categorized according to the urgency of the issue:
•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:
http://www.cisco.com/tac
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 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:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
