router> show version
Cisco Internetwork Operating System Software 
IOS (tm) C1700 Software (C1700-Y-MZ), Version 12.2(8)YL1, EARLY DEPLOYMENT RELEASE SOFTWARE 
(fc1)
Synched to technology version 12.2(5.4)T

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 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. Release 12.2(8)YL1 supports the same feature sets as Releases 12.2 and 12.2(8)T, but Release 12.2(8)YL1 includes 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 6 list the features and feature sets supported in Cisco IOS Release 12.2(8)YL1:

Table 2—Cisco 1710 routers

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

Table 4—Cisco 1721, 1751, and 1760 routers

Table 5—Cisco 1750, 1751, and 1760 routers

Table 6—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(8)YL" means the feature was introduced in 12.2(8)YL. 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(8)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.(8)YL.

New Software Features in Release12.2(8)YL

The following sections describe the new software features supported by the Cisco 1700 series routers for Release 12.2.(8)YL.

Software Based LZ Compression with Hardware Encryption

This feature enables the Cisco 1700 Series routers to support Layer 3 compression (through use of the Lempel-Ziv, or LZ, standard) in software with hardware-based IPSec encryption. Previously, this combination could not be supported.

Benefits

One benefit of this feature is that, through LZ compression, encrypted packets being transmitted are decreased in size, resulting in reduced WAN bandwidth demands. This allows VPNs to be supported more effectively in regions of the world that only utilize low-speed WAN links.

Additionally, by supporting LZ compression with hardware encryption, greater processing power is used for the encryption process, thereby increasing performance. By combining LZ compression with hardware encryption, customers can realize high performance VPNs with reduced bandwidth demands.

Voice Support on Digital T1/E1 Interfaces

Release 12.2(8)YL1 adds voice support to digital T1/E1 interfaces. All the voice functionality that has been supported on analog interfaces (Release 12.2(4)YB) will now be supported on digital T1/E1 interfaces.

The features that are included in this voice support are the following:

MGCP VoIP call admission control

MGCP-based fax (T.38) and DTMF relay

Interactive Voice Response (IVR), Version 2.0

MGCP 1.0

Hoot and Holler over IP

Call admission control for H.323 VoIP gateways

T.37 store and forward fax

Session Initiation Protocol (SIP) for VoIP enhancements

ISDN progress indicator support for SIP using 183 Session Progress

SIP intra-gateway hairpinning

SIP diversion header implementation for redirecting number

SIP configurable PSTN cause code mapping

SIP T.38 fax relay

SIP call transfer using refer method

SIP gateway support for bind command

SIP gateway support for third party call control

DTMF relay for SIP calls using named telephone events

SIP gateway support of RSVP

Cisco IOS Telephony Service Version 2.0, and Survivable Remote Site Telephony (SRSTelephony)

VoFR, H.323 Version 2 support

See the following Cisco IOS release notes for further information regarding these features:

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

Limitations

Data Compression

Packets of size less than 128 bytes or greater than 5000 bytes will not be compressed. Also, all cases of degenerative compression, where the packet is actually expanded rather than compressed, will be discarded, and the original packets will be forwarded.

Maximum Number of Store and Forward Fax Calls

The Cisco 1751 router supports 30 voice calls and the Cisco 1760 router supports 48 voice calls. However, these routers might not be able support more than 10 store and forward fax calls due to memory constraints.

Additional Restriction Information

See the following Cisco IOS release notes for further information regarding limitations and restrictions:

Release Notes for the Cisco 1700 Series Routers for Cisco IOS Release 12.2(8)YJ 

Release Notes for the Cisco 1700 Series Routers for Cisco IOS Release 12.2(4)YB

Release Notes for the Cisco 1700 Series Routers for Cisco IOS Release 12.2(2)XT 

Release Notes for the Cisco 1700 Series Routers for Cisco IOS Release 12.2(2)XH 

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2.(8)YL that can apply to the Cisco 1700 series routers. (Also, see the "Caveats" section.)

T1/E1 VWIC Support on Cisco 1751 and 1760 Routers

The Cisco 1751 and 1760 routers no longer need a voice image to support data applications on T1/E1 VWICs.

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:).

Using Dialer Interface with MLPPPoATM

This feature is not supported on the Cisco 1700 series platforms. Please use the Virtual Template interface instead.

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(8)YL1. 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.

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.

Open Caveats - Release 12.2(8)YL

This section describes unexpected behavior in Release 12.2.(8)YL.

Miscellaneous

CSCdx19900

Packet greater than 5000 bytes fails when SW compression with HW encryption is done.

CSCdx32291

Crypto console error generated when tunnel is initiated via EM module.

CSCdx63850

Broadcast address is being sent as MAC Address in the Cisco 1720, 1721 and 1750 routers when an Ethernet WIC is in slot 1. When there is a one-port Ethernet WIC (WIC-1E) in slot 1 and a TLV 4 EEPROM WIC, like an ADSL WIC, in slot 0, the MAC Address of the Ethernet interface is incorrectly set to the broadcast address ffff.ffff.ffff. The work-around for this problem is to place the Ethernet WIC in slot 0 only.

CSCdx64971

IPSec does not work when set pfs group# is in the configuration. For example:

crypto ap mymap1 11 ipsec-isakmp
 set peer 10.0.0.1
 set security-association level per-host
 set transform-set 1+5+8
 set pfs group2
 match address 101

The work-around for this problem is to remove set pfs group# from the configuration.

CSCdx90637

A Cisco 1700 Series router with a WIC-2AM (2-port asynchronous interface) may reload while issuing the ipx routing CLI. The work-around is to configure ipx routing without running traffic.

CSCdy03960

When configuring MLP, the Cisco 1720 router CPEs crash when an interface is entered into a multilink group. No work-around is available, but it is known that the problem will not occur when using images from Cisco IOS Release 12.2(4)XL.

CSCdy05964

The Cisco 1760 router crashes at bootup if both VIC-2FXO-EU abd VIC-2FXO-M3 interface cards are inserted. Additionally, having the VIC-2FXO-EU card inserted alone will cause a traceback at bootup. There is no work-around.

CSCdy07777

A traceback appears on the router when MGCP calls are made with RSVP, causing the call to fail. This happens when using Call Admission Control with RSVP for MGCP calls. A work-around for this problem is to create a dummy dial-peer as follows:

dial-peer voice 1000 voip
 req-qos guaranteed-delay

CSCin10786

Crash observed when T1 card is in slot 0 and rqnt is sent.

CSCin11036

IVR application is not played in MGCP when sent through CRCX.

CSCin11039

GW uses Cisco fax-relay mode if fx=gw is used in LCO.

Resolved Caveats - Release 12.2(8)YL

This section describes unexpected behavior that is fixed in Release 12.2(8)YL.

Miscellaneous

CSCin09241

The "IPV4_ADDR" identity only is supported.

CSCdw25878

When using SIP, the URL name in the terminating message is not the same as the URL name in the originating message. An IP address shows up instead.

CSCdw92918

Using "bvi/irb/network-extension mode", unable to ping server.

CSCdx47760

If an IP Address is acquired through DHCP and the interface is subsequently shut down, the IP address is not assigned to the Fast Ethernet interface after you enter the following command for the interface: ip address a.b.c.d mask. This occurs on all 1700 platforms.

CSCdy03472

Cisco 1700 Series router with ADSL WIC fails to boot due to insufficient memory.

CSCdy13841

After "service-policy output x" is configured on CE's outbound interface to PE, multi-vrf can only ping the first VRF and the pings to remaining VRFs will fail. Problem remains even after "service-policy output x" is removed.

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:
