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(11)YU1 supports the same feature sets as Releases 12.2(8)T, but Release 12.2(11)YU1 can include new features supported by the Cisco 800 and the Cisco SOHO 70 series routers.

Table 2 through Table 6 list the features and feature sets supported in Cisco IOS Release 12.2(11)YU1:

Table 2—Cisco 826, Cisco 827, and Cisco 827-4H routers

Table 3—Cisco 827-4V router

Table 4—Cisco 828 router

Table 5—Cisco SOHO 76, SOHO 77 and SOHO 77H routers

Table 6—Cisco SOHO 78 router

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(11)YU" indicates that the feature was introduced in 12.2(11)YU. If a cell in this column is empty, then the feature was included in a previous release or the initial base release.


Note These feature set tables contain only a selected list of features. These tables are not cumulative—nor do they list all the features in each image.

New and Changed Information

The following sections list the new software features supported by Cisco IOS Release 12.2(11)YU1 for the Cisco 800 series and the Cisco SOHO 70 series routers.

New Software Features in Release 12.2(11)YU

The following sections list the new software features supported by Cisco IOS Release 12.2(11)YU on the and the Cisco 800 Series Routers.

T.38 Fax Relay

The T.38 Fax Relay for Voice over IP (VoIP) feature provides standards-based fax relay protocol support on the Cisco 827-4V router. The T.38 standard defines the IP network protocol used by Internet-aware T.38 fax devices and T.38 IP fax gateways.

The only method that has been available on the 827-4v for relaying facsimile transmission over IP network is Cisco Fax Relay. Existing Cisco proprietary protocol uses Telogy DSPware and it is handled at the DSP level without any signaling taking place at the H.323 level. This is the default fax protocol if none is configured.

The Cisco proprietary Fax Relay solution is sometimes not ideal for enterprise and service provider customers who have mixed-vendor networks. Because the T.38 Fax Relay protocol is standards based, Cisco gateways and gatekeepers will now be able to interoperate with third-party T.38-enabled gateways and gatekeepers in a mixed-vendor networks that require real time Fax Relay capabilities are required.

The Cisco 827-4V router supports the H.323 Annex D standard for T.38 Fax relay in H.323 networks. A voice call is established first. When a fax tone is detected, fax switch-over takes place.

In addition to H.323 support, the T.38 fax relay feature also supports the Session Initiation Protocol (SIP).

The T.38 fax relay feature supports modem speeds of 2400 bps, 4800 bps, 7200 bps, 9600 bps, 12000 bps, and 14000 bps.

The T.38 fax gateways provide the following functions:

Demodulates incoming T.30 fax signals at the transmitting gateway


Note T.30 is the standard procedure for fax transmission in the public switched telephone network (PSTN).


Translates T.30 fax signals into T.38 Internet Fax Protocol (IFP) packets

Exchanges IFP packets between the transmitting and receiving T.38 gateways

Translates T.38 IFP packets back into T.30 signals at the receiving gateway

Modem Passthrough

The modem passthrough over VoIP feature provides the transport of modem signals through a packet network by using pulse code modulation (PCM)-encoded packets. This feature is supported upto a maximum speed of 28800 bps (28.8 kbps).

The modem passthrough over VoIP feature performs the following functions:

Represses processing functions such as compression, echo cancellation, high-pass filter, and voice activity detection (VAD)

Issues redundant packets to protect against random packet drops

Provides static jitter buffers of 200 ms to protect against clock skew

Discriminates modem signals from voice and fax signals, indicating the detection of the modem signal across the connection, and placing the connection in a state that transports the signal across the network with minimal distortion

Reliably maintains a modem connection across the packet network for a long duration under normal network conditions

Caller ID for Spain and Austria

Caller ID (sometimes called CLID or ICLID for incoming call line identification) is an analog service offered by a central office (CO), which supplies calling party information to subscribers. Typically, the calling party number, and sometimes the name, appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 Caller ID show the calling party information while the call is ringing, and Type 2 Caller ID shows calling number display while the recipient is on another call. Type 1 Caller ID is supported in this release.

The Caller ID feature supports the sending of calling party information from Foreign Exchange Station (FXS) loop-start and ground-start ports into a Caller-ID-equipped telephone device. The FXS port emulates the extension interface of a private-branch exchange (PBX) or the subscriber interface for a CO switch.

Spain and Austria both use the ETSI-FSK method for sending the caller number to the analog phone.

SIP Support for VoIP

Session Initiation Protocol (SIP) is the Internet Engineering Task Force's (IETF's) standard for multimedia conferencing over IP. SIP is an ASCII-based, application-layer control protocol (defined in RFC 2543) that can be used to establish, maintain, and terminate calls between two or more endpoints.

Like other VoIP protocols, SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.

SIP can:

Determine the location of the target endpoint—SIP supports address resolution, name mapping, and call redirection.

Determine the media capabilities of the target endpoint—Using Session Description Protocol (SDP), SIP determines the "lowest level" of common services between the endpoints. Conferences are established using only the media capabilities that can be supported by all endpoints.

Determine the availability of the target endpoint—If a call cannot be completed because the target endpoint is unavailable, SIP determines whether the called party is already on the phone or did not answer in the allotted number of rings. SIP then returns a message indicating why the target endpoint was unavailable.

Establish a session between the originating and target endpoint—If the call can be completed, SIP establishes a session between the endpoints. SIP also supports mid-call changes, such as the addition of another endpoint to the conference or the changing of a media characteristic or codec.

Handle the transfer and termination of calls—SIP supports the transfer of calls from one endpoint to another. During a call transfer, SIP simply establishes a session between the transferee and a new endpoint (specified by the transferring party) and terminates the session between the transferee and the transferring party. At the end of a call, SIP terminates all the sessions.

Conferences can consist of two or more users. Call can be established using multicast or multiple unicast sessions.

CBQoS MIB and DSCP

The Class-Based Quality of Service Management Information Base (CBQoS MIB) provides access to quality of service (QoS) configuration information and statistics. The CBQoS MIB allows service providers to monitor their QoS offerings. This MIB gives QoS configuration done in the router such as ClassMap, PolicyMap, Match Statements and Feature Actions configuration parameters. The MIB also contains counter objects which gives statistics information such as the number of packets traversed conforming to a policing feature. The MIB uses several indexes to identify QoS features and to distinguish among instances of those features. The MIB provides information about marking and policing done using IP precedence and Differentiated Services Code Point (DSCP).

ADSL LED Blinking When DSL Line Trains

ADSL LED Blinking provides information on the status of DSL line. ADSL Tx/Rx is used for this purpose. There are three distinct blinking patterns that indicate the various states of a DSL line when it is training.

1. When the firmware is being downloaded within the router, the LED remains ON for 700 ms and goes OFF for 300 ms.

2. When Modem state is MODEM_ACT_ACK (0x8), it means that the router is waiting to hear from the central office (CO) and is not yet seeing an incoming signal. During this, the LED will be ON and OFF for 50 ms each.

3. When modem state is MODEM_TRAINING (0x10), the LED will always be ON. This means that the DSL line is training.

Shortly after the DSL line has started training, if the modem state changes to SHOWTIME, then the router is successfully trained with the DSLAM.


Note The CD LED on the front panel will be OFF during the DSL line training process. This distinguishes from the normal operation when packets are being transmitted or received.

Resolved Caveats - Release 12.2(11)YU1

Cisco IOS Release 12.2(11)YU1 is a rebuild release for Cisco IOS Release 12.2(11)YU. This section describes unexpected behavior that is fixed in Release 12.2(11)YU1.

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.

This advisory is available at

http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml

Open Caveats - Release 12.2(11)YU

This section describes unexpected behavior in Release 12.2(11)YU.

CSCdy28747

Microsoft MSN Messenger clients using the SIP protocol will not be able to communicate correctly with each other when NAT is enabled on the router. There is no workaround at present.

CSCin11192

Dial-on-demand routing (DDR) is normally triggered by traffic going in the direction opposite the direction for which it is enabled. When DDR is enabled on the Cisco 806 router for inbound traffic, one does not expect DDR to activate upon detecting incoming traffic. However, dial-on-demand router does activate, and the router is assigned an IP address.

CSCin08502

tftp fails with NAT overload when the router listens for tftp traffic on a non-standard port.

CSCdz01412

A Cisco 827-4V router configured for traffic shaping with constant bit rate (CBR) and variable bit rate-non real-time (VBR-nrt) permanent virtual circuits (PVCs) will have the traffic over the CBR PVC affecting throughput on the VBR-nrt PVC. The CBR PVC will also not be shaped and will be send at line rate.

Workaround

Increase the peak cell rate (PCR) and sustained cell rate (SCR) parameters of the VBR-nrt virtual circuit.

CSCin25256

EzVPN Tunnel fails to come up after configuring XAUTH. This requires Cisco IOS running on the remote EzVPN server to be upgraded to Cisco IOS release 12.2-13.T or later.

CSCdz59316

In the Cisco 82x router, PPP over ATM using aal5mux encapsulation on the dialer interface will not fast switch packets, instead packets will get process switched.

Workaround

Enable ip cef in the router.

CSCdz61900

Cisco 827-4V router reloads when debug vtsp all is enabled for T.38 fax relay with Cisco Fallback option and when a Cisco fax-relay call is recieved.

Workaround

Disable debug vtsp all.

Resolved Caveats - Release 12.2(11)YU

This section describes problems that were fixed in Release 12.2(11)YU.

CSCin14702

The HSRP interface track command sets the decrement value for an interface. It can also be used to modify the decrement value associated with an interface. At any given time, it is possible to have only one such command active for an interface.

However, the router seems to allow multiple track commands to be applied to an interface. Thus, more than one command can be active at any time. The commands are accumulated instead of being overwritten. When the interface goes down, the decrement values specified in all these commands are added up, and the resulting value is used as the decrement value.

Workaround

Use the no version of the track command to disable the previous setting for the interface, before issuing a new track command to change the decrement value. This will prevent accumulation of track commands.

CSCin11465

Easy VPN split tunneling extended access control list issue. This occurs when split tunneling is used in client mode. If the access list at the remote end is configured with two entries that have the same source IP address, the Cisco 806 client will try to install the same address twice and will clean up all the NAT configurations. In this case, one expects NAT to fail. However, on the Cisco 806 router, NAT continues to work correctly.

CSCin11017

In lab test scenarios, the Cisco 806 router client crashes after the idle timeout expires for DDR.

CSCdx72437

On a heavily loaded ATM VC, F5 OAM cells may be dropped by the Cisco 827 router causing the PVC to flap up and down. This flapping is not observed on the CPE but is visible on the aggregation device or on the remote end of the PVC.

CSCdz55586

In the Cisco 82x router, max-reserved-bandwidth command does not work, when configured on the ATM interface. This issue has been resolved in this release.

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:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

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

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
