Upgrading to a New Software Release

For general information about upgrading to a new software release, see Software Installation and Upgrade Procedures located at: http://www.cisco.com/warp/public/130/upgrade_index.shtml.

Feature Sets

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. Release 12.2(4)YA7 supports the same feature sets as Releases 12.2 and 12.2 T, but Release 12.2(4)YA7 include new features supported by the Cisco 1700 series routers.


Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders can be denied or subject to delay due to United States government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 through Table 5 list the features and feature sets supported in Cisco IOS Release 12.2(4)YA7:

Table 2—Cisco 1710 routers

Table 3—Cisco 1720, 1721, 1750, 1751, and 1760 routers

Table 4—Cisco 1750, 1751, and 1760 routers

Table 5—Cisco 1751 and 1760 routers

The tables use the following conventions:

Yes—The feature is supported in the software image.

No—The feature is not supported in the software image.

In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, "12.2(4)YA" means the feature was introduced in 12.2(4)YA. If a cell in this column is empty, the feature was included in a previous release or the initial base release.


Note These feature set tables only contain a selected list of features, which are cumulative for Release 12.2(4)nn early deployment releases only (nn identifies each early deployment release). The tables do not list all features in each image—additional features are listed in the Cross-Platform Release Notes for Cisco IOS  Release 12.2 T  and Release 12.2 T Cisco IOS documentation.

New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 1700 series routers for Release 12.2(4)YA7.

New Hardware Features in Release 12.2(4)YA

The following sections describe the new hardware features supported by the Cisco 1700 series routers for Release 12.2(4)YA.

Cisco 1721 Router

The Cisco 1721 data-only modular access router is an enhanced Cisco 1720 router that provides higher performance, additional functionality, and increased memory capacity. The router supports WAN access, VPN, and firewall technology for secure Internet, intranet, and extranet access. Cisco 1721 routers also support standards-based Institute of Electrical and Electronic Engineers (IEEE) 802.1Q VLAN routing, which enables enterprises to set up and route between multiple VLANs for additional security in an internal corporate network.

The Cisco 1721 router includes the following key hardware features:

Support for virtual private networking.

One internal expansion slot—Supports hardware-assisted services such as encryption (up to T1/E1 speeds)

Modular architecture.

Network device integration.

The Cisco 1721 router has the following hardware components:

One integrated, autosensing 10/100 Fast Ethernet port, which operates in full- or half-duplex mode (with manual override available), and supports IEEE 802.1Q VLAN features.

Two WAN interface card (WIC) slots.

One auxiliary (AUX) port (up to 115.2 kbps asynchronous serial).

One console port.

Flash memory: 16 MB default.

DRAM: 32 MB default, expandable to 96 MB.

RISC Processor—Motorola MPC860P PowerQUICC at 50 MHz.

Desktop form factor.

Locking power connectors.

One security slot that supports Kensington or similar lockdown equipment.

Cisco 1721 routers support any combination of one or two of the following WICs:

WIC-1T—One-port high speed serial (sync/async)(T1/E1).

WIC-2T—Two-port high speed serial (sync/async) (T1/E1).

WIC-2A/S—Two-port low speed serial (sync/async) (up to 128 kbps).

WIC-1B-S/T—One-port ISDN BRI S/T.

WIC-1B-U—One-port ISDN BRI U with integrated NT1.

WIC-1DSU-56K4—One-port integrated 56/64 kbps 4-wire DSU/CSU.

WIC-1DSU-T1—One-port integrated T1 / Fractional T1 DSU/CSU.

WIC-1ADSL—One-port asymmetric digital subscriber line.

WIC-1ENET—One-port 10Base-T Ethernet interface.

WIC-1G.SHDSL—One-port G-Standard High bit-rate Digital Subscriber Loop.

New Software Features in Release 12.2(4)YA

The following sections describe the new software features supported by the Cisco 1700 series routers for Release 12.2(4)YA.

Cisco Easy VPN Client

Applications for routers (and other forms of broadband access devices) that provide high-performance connections to the Internet often require the security of virtual private network (VPN) connections with a high level of access authentication and the capability to encrypt data between two endpoints. However, establishing a VPN connection between two routers can be complex, and typically requires detailed coordination between network administrators to configure the router VPN parameters.

The Cisco Easy VPN client feature eliminates much of this work by implementing the Cisco Unity Client protocol, which allows most VPN parameters to be defined at a VPN 3000 concentrator, acting as an IPSec server. After network administrators configure the IPSec server, they can create a VPN connection with minimal configuration on an IPSec client (such as a Cisco 1700 series router). When the IPSec client initiates the VPN tunnel connection, the IPSec server transmits the IPSec policies to the IPSec client and creates the corresponding VPN tunnel connection.

New Software Features in Release 12.2(4)T

For information regarding the features supported in Cisco IOS Release 12.2 T, refer to the Cross-Platform Release Notes and New Feature Documentation links at the following location on CCO:

Service & Support: Technical Documents: Cisco IOS Software: Release 12.2: Release Notes:  Cross-Platform Release Notes (Cisco IOS Release 12.2T) 

Limitations

Release 12.2(4)YA7 does not support Global system for mobile communication over frame relay (GSM-FR) on Cisco 1700 series routers on the Cisco 1700 series routers. (Also, see the "Caveats" section.)

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(4)YA7 that can apply to the Cisco 1700 series routers. (Also, see the "Caveats" section.)

NT Firmware Upgrade to ASW3_8_129 for the ADSL Physical-Layer System

Cisco IOS Release 12.2(4)YA and above requires an upgrade to Alcatel Microelectronics ASW3_8_129 firmware, which is an upgraded release of the NT firmware for the ADSL physical-layer system. The firmware implements a multi-mode modem that operates according to the ANSI T1.413, ITU G.992.1 and ITU G.992.2 ADSL standards. The firmware upgrade is a maintenance release of the ADSL-ASW_R3_x_x family, to incorporate support for single-line Utopia platforms.

The operation of the ASW3_8_129 runtime software is described in detail in the CTRLE Interface Specification 3.10 available on Cisco.com and the Documentation CD at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122relnt/1700/1700ya/alcatlfw.pdf 

This URL is subject to change without notice. If it changes, point your web browser to CCO, and click the following path:

Service and Support: Technical Documents: Cisco IOS Software: Release 12.2: Release  Notes: Cisco 1700 Series RoutersCisco 1700 Series - Release 12.2(4)YA: Alcatel Modem  Firmware ASW_3_8_129 Release Notes 

Fan Operation in Cisco 1700 Series Routers

Cisco 1760 and 1760-V router fans are always on and Cisco 1710 routers do not contain a fan. However, the fans in Cisco 1720, 1721, 1750, and 1751 routers stay off until thermally activated.

Flash defaults to Flash:1 on Multipartition Flash

When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.

Peak Cell Rate and Sustainable Cell Rate Values

On Cisco 1700 routers, specify the Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR) as multiples of 32 Kbps. Other rates are treated as the next lower value of a multiple of 32. For example, an entered PCR value of 150 is considered 128.

Using the boot flash Command

Booting a Cisco 1700 series router with the commands boot flash or boot system flash results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:.)

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 12.2(4)YA7. 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 and the Documentation CD.


Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity.

Cisco IOS Release 12.2(4)YA6 is a rebuild release for Cisco IOS Release 12.2(4)YA. This section describes unexpected behavior that is fixed in Release 12.2(4)YA6.

Miscellaneous

CSCdz71127

Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available.

Cisco has made software available, free of charge, to correct the problem.
