Introduction
Cisco Systems extends enterprise-class and managed services Customer Premises Equipment (CPE) versatility, integration, and power to branch offices with the Cisco 2600 series modular access router family. The widely deployed Cisco 2600 series modular access routers are designed to enable customers to easily adopt future technologies and scale to accommodate network expansion. The Cisco 2600 series shares modular interfaces with the Cisco 1600, Cisco 1700, and Cisco 3600 series, providing a solution to meet today's branch office needs for applications such as the following:
•
•
•
•
•
•
The Cisco 2600 series modular architecture provides the versatility needed to adapt to changes in network technology as new services and applications become available. Driven by a powerful reduced instruction set computing (RISC) processor, the Cisco 2600 series supports the advanced Quality of Service (QoS), security, and network integration features required in today's evolving enterprise networks.
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1(3) XQ4, see the "New and Changed Information" section section and the "Related Documentation" section.

Determining the Software Version
To determine the version of Cisco IOS software running on a Cisco 2600 series router, log in to the router and enter the show version EXEC command:
router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 2600 Software (c2600-is-mz), Version 12.1(3) XQ4, RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, refer to Software Installation and Upgrade Procedures located at the following URL:
http://www.cisco.com/warp/public/130/upgrade_index.shtml
Microcode Software
Microcode software images ship on the flash along with the system software image. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface linecards.
It is possible to use a later version of microcode than the one shipped with the Cisco IOS software from the factory. The microcode in Flash memory is mapped to the linecards. Unless you fully understand how Cisco IOS software uses microcode, it is important to keep the factory configuration.
The point-to-multipoint wireless modem card requires external microcode. Information about this microcode will be available on Cisco.com in November.
Other Firmware Code
The latest version of analog modem firmware for the Cisco 2600 series supports the internal analog modems (both NM-16AM and NM-8AM) in a wide range of countries, starting with Cisco IOS Release 11.3(5)T and later releases. The latest firmware (version 1.2.0) also supports dial-out and fax-out.

New Hardware Features in Cisco IOS Release 12.1(3)XQ
The following new hardware feature is supported by the Cisco 2600 series for Cisco IOS Release 12.1(3) XQ.
Wireless Network Module
The NM-WMDA wireless network module installs in the network module slot of a Cisco 2600 series router. Installing a wireless network module enables the Cisco 2600 series router to act as a subscriber unit (SU) in a point-to-multipoint wireless network. It is configured through the router's system console or via the CiscoView network management system. The network module provides the control and data interface between the Cisco 2600 series digital motherboard and the radio frequency (RF) subsystem in the wireless transverter. It also provides the up/down conversion from baseband to intermediate frequency (IF). One network module supports one or two wireless transverters (main and diversity).
The wireless network module requires external microcode. Information about this microcode will be available on Cisco.com in November.
For further information regarding the network module, refer to the Cisco Network Modules Hardware Installation Guide (for Cisco 2600 series routers) for detailed installation instructions, and the Software Configuration Guide (for Cisco 2600 series routers) for an overview of network module configuration procedures and information on configuring specific network modules.
New Software Features in Cisco IOS Release 12.1(3) XQ4
The following new software feature is supported by the Cisco 2600 series for Cisco IOS
Release 12.1(3) XQ4.
Point to Multipoint Wireless
The Cisco broadband fixed wireless point-to-multipoint system is an integrated solution consisting of one headend and multiple subscriber units. The fixed wireless point-to-multipoint subscriber unit is designed to receive radio frequency (RF) signals from the headend. It also transmits a return signal to the headend. This return signal is a point-to-point signal, so a properly installed subscriber antenna must be correctly oriented with the headend antenna to which it is transmitting. For more information about the fixed wireless point-to-multipoint headend feature, see the Point-to-Multipoint Support for the Cisco uBR7200 Series Universal Broadband Router.
Important Notes
The following sections contain important notes about Cisco IOS Release 12.1(3) XQ4 that can apply to the Cisco 2600 series.
Product Number Change
Beginning with Cisco IOS Release 12.0(7) XK, Cisco changed the product numbers used to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
MIBs
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs—without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 5.
Note
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. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
For information on caveats in Cisco IOS Release 12.1(3) T, see Caveats for Cisco IOS Release 12.1T that accompanies these release notes. This document lists severity 1 and 2 caveats and selected severity 3 caveats for Cisco IOS Release 12.1T.
All caveats in Cisco IOS Release 12.1(3a)T1 are also in Cisco IOS Release 12.1(3) XQ4.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and is located on Cisco.com and the Documentation CD-ROM.

Open Caveats—Cisco IOS Release 12.1(3) XQ4
There are no open caveats specific to Cisco IOS Release 12.1(3) XQ4 that require documentation in the release notes.
Resolved Caveats—Cisco IOS Release 12.1(3) XQ4
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(3) XQ4. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
An error can occur with management protocol processing. Please use the following URL for further information:
http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903
Open Caveats for Release 12.1(3) XQ3
This section documents possible unexpected behavior by Cisco IOS Release 12.1(3) XQ3, and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
During brief periods of high-traffic activity on the subscriber-unit router and with the router's CPU overloaded, the radio "link-metrics" (continuous codeword error statistics) might not be collected because network-packet traffic has priority over the radio "link-metrics" on the CPU. This might cause the "link-metrics" tables to show zeros only and/or error messages to be generated. There is no workaround.
•
The system will accept a statistic parameter for a second antenna even though it is a single-antenna system.
Workaround: Disregard data for the second antenna.
Closed and Resolved Caveats for Release 12.1(3)XQ3
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(3)XQ3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
When the radio debugging function is enabled via the debug radio command, none of the radio debugging flags appear in the output of the show debug command. This makes it difficult to determine if the radio debugging function is turned on. There is no workaround.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
The Cisco vendor-specific DOCSIS TLV 129, which performs a Cisco IOS configuration file download without disabling the console, is not supported.
Workaround: Use DOCSIS TLV 128, which performs a Cisco IOS configuration file download, but does disable the console afterwards.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3: DOCSIS TLV 129 is now supported.
•
Tag-Length-Value (TLV) option 43.129, which is used to download an Cisco IOS configuration file without disabling the console, is currently not supported on the Cisco 2600 routers functioning as subscriber units.
Workaround: Use TLV option 43.128, which is used to download an Cisco IOS configuration file and requires disabling the console.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3: TLV option 43.129 is now supported.
•
Connection setup improvements.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
