Contents

These release notes describe the following topics:

Introduction

The Cisco AS5300 universal access server is a versatile data communications platform that provides the functions of an access server, router, and digital modems in a single modular chassis. The access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, as well as medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog to digital dial access services.

For information on new features and Cisco IOS commands supported by Release 11.3 NA, refer to the "New and Changed Information" section and the "Related Documentation" section.

Upgrading to a New Software Release

For information about upgrading to a new software release, see the Cisco IOS Software Release 11.3 Upgrade Paths and Packaging Simplification  product bulletin located on CCO at:

Service & Support: Product Bulletins: Software

Under Cisco IOS 11.3, click Cisco IOS Software Release 11.3 Upgrade Paths (#703: 12/97)

This product bulletin does not contain information specific to Cisco IOS Release 11.3, but provides generic upgrade information that may apply to Cisco IOS Release 11.3.

Microcode and Modem Code Software

Microcode is the firmware or portware that runs on the Microcom 12-port or MICA 6-port modem cards. Microcode software images are bundled with the system software image---with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the access server starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards.

Note You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.

You can reach the release notes on CCO at:

Service & Support: Technical Documents: Cisco Product Documentation: Access Servers and Access Routers: Firmware and Portware Information

You can reach the release notes on the Documentation CD-ROM at:

The show modemcap command lists all versions of modem code running on the modem modules, residing in system Flash, and bundled with Cisco IOS software. Enter the show modemcap command to help you decide if you need to update your modem code files.

The Cisco IOS Software Upgrade Planner on CCO contains information about downloading software. To access this document from CCO, click Login on the CCO home page to access all information. From the CCO home page, go to the Software Support area, click Software Center, then Cisco IOS Software or IOS Upgrade Planner.

Feature Set Table

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 11.3(11)NA supports the same feature sets as Release 11.3 T, but Release 11.3(11)NA can include new features supported by Cisco AS5300 universal access servers.

Note Encryption feature sets are not provided in this release. The names of the images are listed in the "Memory Requirements" section .

New and Changed Information

This section lists new features available for the AS5300 for Release 11.3(11)NA.

No New Features in Release 11.3(8)NA through 11.3(10)NA

No new features were introduced in Release 11.3(8)NA through 11.3(11)NA for the Cisco AS5300 universal access server.

New Features in Release 11.3(7)NA

This section describes the new features for the Cisco AS5300 universal access server in Cisco IOS Release 11.3(7)NA.

E1 R2 Support

R2 signaling support has been added to existing ISDN PRI over a channelized E1 interface. This feature is available in countries supporting R2 signaling.

Interactive Voice Response

The following two new Interactive Voice Response (IVR) scripts have been added to this release:

This script is similar to clid_authen_col_npw, but it allows two retries (3 tries total) for entering the account and password. For each of the two retries, it plays a special retry message.
This is similar to clid_col_npw_3, but it does not collect a personal identification number (PIN). Instead, it uses the collected account number with a NULL password for authentication.

New Features in Release 11.3(6)NA2

This section describes the new features for the Cisco AS5300 universal access server in Cisco IOS Release 11.3(6)NA2, which introduced features supported by IP Telephony. For detailed information about these features, refer to Configuring the Cisco AS5300 for Voice Service Provider Features , which is an addendum to the Cisco AS5300 Software Configuration Guide .

The IP Telephony features include enhancements made to the functionality and configuration of both the gateway and the VoIP gatekeeper. The architecture of these features provides the quality of service (QoS), stability, and functionality necessary for carrier class real-time IP communications services. The Cisco gateway functionality and gatekeeper functionality work in concert to provide the ITU-T H.323 infrastructure.

To provide understanding of which features affect which portions of the internetworking environment, the various IP Telephony features are described in the following two categories:

Gatekeeper

The gatekeeper can manage a zone and provide bandwidth management and address resolution services to gateways when present in the network.

Gateway RAS Implementation

This refers to the Cisco AS5300 universal access server with voice cards and the Voice over IP (VoIP) image. Gateways are also referred to as VoIP gateways.

The gateway can terminate a call from the public switched telephone network (PSTN), provide user admission control using interactive voice response (IVR), direct the call to the destination, terminate the call from another gateway and send the call to the PSTN, and finally provide accounting records for the calls.

Registration, Admission, and Status (RAS) is a signaling function that performs registration, admissions, status, and disengage procedures between the VoIP gateway and the gatekeeper.

The gateway relies on Cisco IOS command-line interface commands outside the gateway configuration mode to configure the AAA servers. The two following RAS command fields have been added to the dial-peer entry to enable the RAS implementation:

AAA Enhancements

AAA represents authentication, authorization, and accounting features that are required in the VoIP gateway. The standard Cisco AAA functionality is enhanced to allow calls to:

The AAA authentication feature permits RADIUS to authenticate users on the gateway. It is normally used with IVR to check the legitimacy of a prospective gateway user based on an account number (collected by IVR) or based on answer number identification (ANI).

Interactive Voice Response

This application provides basic IVR capabilities necessary to collect caller PINs, passwords, and destination phone numbers. IVR consists of simple voice prompting and digit collection to collect information from the caller for the purpose of authenticating the caller and identifying the destination.

"Simple" IVR allows the use of one of several interactive voice response scripts embedded in Cisco IOS software. The ability to modify the embedded scripts is not yet provided. However, you can modify the audio files (for the prompts).

The IVR application:

An IP/PSTN gateway can have several different IVR applications to accommodate many different gateway services.

ISDN Redirect Number Support

This feature supports the redirecting call feature of the VoIP gateway. The redirecting number is an optional field of the Q.931 setup message.

When a local exchange carrier (LEC) switch detects an incoming call that is destined for a busy or nonanswering party, the switch formulates a Q.931 setup message with the redirecting number field set to the originally called number, and sends it to the gateway. The called party number of the setup message will be set to one of the DNIS access numbers belonging to the gateway.

If a redirect number is present in an incoming call, then it is used in place of the called number (DNIS).

Rotary Call Pattern

This feature provides the ability, under certain circumstances, to route an incoming call arriving by one telephony interface back out by another telephony interface. This is primarily used to provide reliable service during network failures. Call establishment via Rotary Call Pattern will be supported via rotary group support of dial peers where multiple dial peers may match a given destination telephone number and will be selected in sequence.

In prior releases of VoIP, if you wanted the system to search through a number of destinations when a given number was dialed, you needed to configure those dial peers with the same destination pattern. Now with the Rotary Call Pattern feature, if you want the destinations to be tried in a certain order, you can assign preference (using the preference command) to the dial peers to reflect the desired order.

T1 CAS

Channel Associated Signaling (CAS) is the transmission of signaling information within the voice channel. In addition to receiving and placing calls, T1 CAS:

The development of this feature enhances and integrates T1 CAS capabilities on the DSP Module (DSPM) in order to support central office (CO) and PBX configurations for voice calls.

No New Features in Release 11.3(4)NA through 11.3(6)NA

No new features were introduced in these releases for the Cisco AS5300 universal access server.

No Release 11.3(3)NA

Cisco IOS Release 11.3(3)NA was not released.

New Features in Release 11.3(2)NA

This section describes the new features for the Cisco AS5300 universal access server in Cisco IOS Release 11.3(2)NA.

Voice over IP

The Voice over IP (VoIP) software enhancement was added to the Cisco AS5300 platform for Cisco IOS Release 11.3(2)NA. VoIP enables a Cisco AS5300 to carry live voice traffic (for example, telephone calls and faxes) over an IP network.

When used as a PTSN gateway, VoIP leverages the standardized use of H.323-based Internet telephone client applications.

VoIP on the Cisco AS5300 supports two primary applications:

Major customer applications for VoIP include:

To use VoIP, which is primarily a software feature on the Cisco AS5300, you must install the VoIP feature card (VFC) that contains multiple digital signal processor (DSP) modules. The VFC uses the Cisco AS5300 quad T1/E1 PSTN interface and LAN or WAN routing capabilities to provide up to a 48- or 60-channel gateway for VoIP packetized voice traffic to and from T1/E1 time-division multiplexing (TDM) traffic.

Features in the Parent Release 11.3 T

Features for the Cisco AS5300 in Release 11.3 T are also supported in the current Cisco IOS Release 11.3 NA. For information about these features, see the current Release Notes for Cisco AS5300 for Cisco IOS Release 11.3 T.

Features added to the Cisco AS5300 for Cisco IOS Release 11.3 T between Cisco IOS Releases 11.3(2)T and Cisco IOS Release 11.3.(8)T, are not supported in Cisco IOS Release 11.3(10)NA unless they have also been added separately to Cisco IOS Release 11.3 NA and support is explicitly stated to coincide in the release notes for Cisco IOS Release 11.3(10)NA. Currently, no such features have been added. Check the feature set in the Release Notes for Cisco AS5300 for Cisco IOS Release 11.3 T to determine at which maintenance release a given feature was added.

Limitations and Restrictions

Release 11.3 NA is an Early Deployment (ED) release of software to support the Cisco AS5300 universal access servers. Release 11.3 NA is the same as Release 11.3 T, except that the following caveats have been resolved in Release 11.3 NA:

AAA Accounting

If you are using CiscoSecure ACS for Windows NT and H.323 accounting (AAA accounting), use version 2.1.8.4 or higher of CiscoSecure.

MICA and Microcom Modems

You can use a voice card in the Cisco AS5300 with MICA modems installed in the other feature card slot, but the equivalent configuration with Microcom modems is not supported.

Note You cannot use VoIP and Microcom modems at the same time.

Open Caveats---Release 11.3(11)NA

This section describes possibly unexpected behavior by Release 11.3(11)NA and describes only severity 1 and 2 caveats.

Miscellaneous

BPI MIB will now be available in released code.
When running 11.3.10NA image, ingress gw may display wrong cause code.
This fixes CM status display in CMTS when the modem goes offline with BPI turned on and key expiration.

Resolved Caveats---Release 11.3(11)NA

All the caveats listed in this section are resolved in Release 11.3(11)NA. This section only describes severity 1 and 2 caveats.

Basic System Services

Certain Internetwork Status Monitor (ISM) NetView users can issue non-enable mode commands without router authentication. Users accessing the router through NetView must be authenticated through NetView's security methods, which may include RACF and SAF. Mainframe users can be restricted from issuing any router commands through the restriction of the RUNCMD within NetView. Users issuing enable mode commands must be authorized to issue this level of command through ISM, and must possess the ENABLE mode password. If the router is controlled by TACACS+, the ISM user must have a TACACS+ User ID and Password to issue enable level commands.

IBM Connectivity

There is a problem whereby DLSw Lite peers leak CLS connect request buffers. If possible, the customer can try using a different peer type. This patch will free an outstanding connect request if additional requests are received while the first is still pending.

Interfaces and Bridging

Symptom: Crash in frf9_preComp()
Condition: Mostly frequently will occur during times when router traffic is heavy which causes memory usage to increase and a possible low memory condition to occur.
Workaround: Disable compression or use a different type.
Miscellaneous: Since this problem is aggravated by a low memory condition tuning the memory tuning can help prevent it from occurring but will not guarantee it can not happen.
This is caused by an over-write issue in BSS area with FDDI modules equipped which has potential to cause serious problem such as crash in 12.0T.
A PA-4R-DTR port may reset under the following circumstances:
When this problem occurs, the PA-4R-DTR port will reset, and the ring will experience a beacon.
Workaround: Make sure the DTR port is not the active monitor on the ring. This can be done by ensuring that the MAC-address of the DTR card is not the highest MAC-address on the physical ring.

IP Routing Protocols

IP access lists fail to block pings on interfaces configured for policy routing with IP route-cache policy.
Some IP fragments may be incorrectly filtered out by access lists.
DNS replies passing from "inside" to "outside" via NAT are not NAT translated correctly in many cases. There is no work around.

Miscellaneous

AS5300 will get bus error when under heavy load caused by outgoing Modem calls. Have tested with IOS 11.3(9)T and 11.3(8.5)T with same results.
Problem is reproducible within minutes.
Problem description: When "cable ip-broadcast-echo" is enabled, under certain timing conditions may cause a buffer leak.
Workaround: Do not enable "cable ip-broadcast-echo" and "cable ip-multicast-echo".
Symptom : The NM-1FE-TX fails to autonegotiate properly when connected through an SMF connector.
Analysis : Setting the speed to 100 manually solves the problem. An interface speed command with the following syntax is being added to overcome this. The default behaviour would be to autonegotiate.
[no] speed {10 | 100 | auto}
When port info is passed from LAC and 'vpdn aaa attribute nas-port vpdn-nas' is configured, it should be mapped to correct NAS-Port-Type value.
Configuring PPP encaplusation on an interface and the making that interface a member of a bridge group gives tracebacks and fair-queue not properly initialized messages. Remove brdging from the interface or turning off fair queue the massages dissappear.

Under conditions of stress (if the ESA is bringing up a large number of crypto sessions simultaneously), it may either enter a race condition or get the crypto initiation messages wedged in the input-q of the interface doing encryption.

Wide-Area Networking

DDR with dialer dtr does not reset DTR to a down state after an unsuccessful call attempt. Unsuccessful in this case means that DDR is triggered, DTR is raised, but the modem/TA attached to the serial port never connects so that DCD does not come up.
This can be verified by viewing show dialer to ensure that the dialer state is idle, and then show interface serial x to check the state of DTR.
Customer is deterministically getting a crash (segV) when dialer rotor best is configured and 'deb dialer' is started once traffic trigger a call.
Reliable PPP can cause an intermittent crash when used with WFQ. Workaround is to disable Reliable PPP or WFQ.
