Introduction

The Cisco AS5100 and Cisco AS5200 universal access servers are supported in Cisco IOS Release 11.3(11)T. With their optimization for high-speed modem access, the Cisco AS5100 and Cisco AS5200 universal access servers are ideally suited for all traditional dial-up applications, such as host access, electronic mail, file transfer, and dial-in access to a local area network (LAN).

Cisco AS5100 Universal Access Server

The Cisco AS5100 universal access server is a versatile data communications platform that combines all the functions of an access server, a router, and analog and digital modems into one chassis. Organizations requiring centralized processing capabilities for mobile users and telecommuters will benefit the most from using the Cisco AS5100 universal access server.

Cisco AS5200 Universal Access Server

The Cisco AS5200 universal access server is a multifaceted data communications platform that provides all of the functions of an access server, a router, modems, and terminal adapters (TAs) in a modular chassis. Mid-sized organizations or service providers requiring centralized processing capabilities for mobile users and telecommuters will benefit the most from using the Cisco AS5200 universal access server.

Updating 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: Technical Documents: 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.

Modem Code

Cisco IOS Release 11.2(1) and later includes bundled modem code for the Cisco AS5200, which is the firmware or portware that runs on the Microcom 12-port and MICA 6-port modem cards. Bundling eliminates the need to store separate microcode images. When the access server starts, the Cisco IOS software unpacks the modem code and loads the proper code on the modem cards.

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.

The modem code release notes are on CCO and the Documentation CD-ROM:

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 may be denied or subject to delay due to United States government regulations. When applicable, 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.

New and Changed Information

The following sections list the new features supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3 T. For more information about these features, see the "Related Documentation" section.

No New Features in Release 11.3(7)T through Release 11.3(11)T

There are no new hardware or software enhancements supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(7)T through Release 11.3(11)T.

New Software Features in Release 11.3(6)T

The following new software enhancements are supported by the Cisco AS5100 and Cisco AS5200 access servers in Cisco IOS Release 11.3(6)T and later releases.

New cas-custom Commands---Cisco AS5200 Only

The following three new cas-custom commands are available for the Cisco AS5200 in Cisco IOS Release 11.3(6)T:

Additional E1 R2 Signaling Support

The following additional countries now support E1 R2 signaling:

See the "E1 R2 Signaling" section for more information about this feature.

No New Features in Release 11.3(5)T

There are no new hardware nor software enhancements supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(5)T.

New Software Feature in Release 11.3(4)T

The following new software enhancement is supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(4)T and later releases.

IP Type of Service and Precedence for GRE Tunnels

Before the IP Type of Service and Precendence for GRE Tunnels  feature, at generic route encapsulation-based tunnel endpoints, the Type of Service (TOS) bits (including precedence bits) were not copied to the tunnel or GRE IP header that encapsulates the inner packet. Instead, those bits were set to zero. This was not a problem unless the intermediate routers between two tunnel endpoints honored TOS or precedence bits, in which case those settings were ignored.

With the advent of virtual private network (VPN) and Quality of Service (QoS) applications, it is desirable to use GRE to copy the TOS bits when the router encapsulates the packets. Thus, intermediate routers between tunnel endpoints can take advantage of the QoS features, such as weighted fair queuing (WFQ) and weighted random early detection (WRED).

New Software Features in Release 11.3(3)T

The following new software enhancements are supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(3)T and later releases.

Named Method Lists for AAA Authorization and Accounting

In earlier Cisco IOS releases, only named authentication method lists were supported under Cisco's Authentication, Authorization, and Accounting (AAA) network security services. With Cisco IOS Release 11.3(3)T, AAA was extended to support both authorization and accounting named method lists.

Named method lists for authorization and accounting  function the same way as those for authentication: They allow you to define different methods for authorization and accounting and apply those methods on a per-interface or per-line basis.

Additional Vendor-Proprietary RADIUS Attributes

Remote Authentication Dial-In User Server (RADIUS) is an access server authentication, authorization, and accounting protocol originally developed by Lucent Technologies Remote Access Business Unit (formerly Livingston, Inc.). Although an Internet Engineering Task Force (IETF) draft standard for RADIUS specifies a method for communicating vendor-proprietary information between the network access server and the RADIUS server, some vendors have extended the RADIUS attribute set in a unique way. In this release, Cisco IOS software introduces support for additional vendor-proprietary RADIUS attributes.  Users who have implemented security solutions using a vendor-proprietary implementation of RADIUS can now integrate Cisco access routers into their networks more easily.

For a complete list of supported IETF and vendor-proprietary RADIUS attributes, see the "RADIUS Attributes"  appendix in the Cisco IOS Release 11.3 Security Configuration Guide.

Automated Double Authentication

The Automated Double Authentication  feature enhances the existing double authentication feature.

Previously, with the existing double authentication feature, a second level of user authentication is achieved when the user Telnets to the network access server or router and enters a username and password. Now, with automated double authentication, the user does not have to Telnet anywhere but instead responds to a dialog box that requests a username and password or PIN.

For information about the existing double authentication feature, see the "Configuring Authentication"  chapter of the Cisco IOS Release 11.3 Security Configuration Guide.

Microsoft Point-to-Point Compression (MPPC)

Microsoft Point-to-Point Compression (MPPC)  is a scheme used to compress Point-to-Point Protocol (PPP) packets between Cisco and Microsoft client devices. The MPPC algorithm is designed to optimize processor and bandwidth utilization in order to support multiple simultaneous connections. The MPPC algorithm uses a Lempel-Ziv (LZ)-based algorithm with a continuous history buffer, called a dictionary.

MS-CHAP Support

Microsoft Challenge Handshake Authentication Protocol (MS-CHAP)  is the Microsoft version of CHAP. Like the standard version of CHAP, MS-CHAP is used for PPP authentication; in this case, authentication occurs between a PC using Microsoft Windows NT or Microsoft Windows 95 and a Cisco router or access server acting as a network access server (NAS).

MS-CHAP differs from the standard CHAP as follows:

Depending on the security protocols you have implemented, PPP authentication using MS-CHAP can be used with or without Authentication, Authorization and Accounting (AAA) security services. If you have enabled AAA, PPP authentication using MS-CHAP can be used in conjunction with both TACACS+ and RADIUS.

For a complete list of supported IETF and vendor-proprietary RADIUS attributes, see the "RADIUS Attributes" appendix in the Cisco IOS Release 11.3 Security Configuration Guide.

Multiple ISDN Switch Types

The Multiple ISDN Switch Types  feature allows you to configure more than one ISDN switch type per router. You can apply an ISDN switch type on a per interface basis, thus extending the existing global isdn switch-type command to the interface level. This allows Basic Rate Interfaces (BRI) and Primary Rate Interfaces (PRI) to run simultaneously on platforms that support both interface types.

The isdn tei command is also extended to the interface level. Terminal endpoint negotiation (TEI) determines when Layer 2 is activated (powerup or first-call).

National ISDN Switch Types for Basic Rate and Primary Rate Interfaces (NI2)

National ISDN Switch Types for Basic Rate and Primary Rate Interfaces  introduces changes to ISDN switch types for Primary Rate Interfaces (PRI) and Basic Rate Interfaces (BRI) as follows:

Note The command parser will still accept the following switch types: basic-nwnet3, vn2, and basic-net3: However, when viewing the NVRAM configuration using either the show running configuration or write terminal command, the basic-net3 or vn3 switch types are displayed respectively.

VPDN MIB and Syslog Facility

The Virtual Private Dialup Network (VPDN) Management Information Base (MIB)  feature is intended to support all the tables and objects defined in "Cisco VPDN Management MIB" for the user sessions of the VPDN features. There are a number of commands which provide information and statistics through the Command Line Interface (CLI) but not Simple Network Management Protocol (SNMP); the Cisco VPDN MIB and Syslog Facility has been created to satisfy the need to provide information and statistics through SNMP.

Always On/Dynamic ISDN (AO/DI)---Cisco AS5200 only

Always On/Dynamic ISDN (AO/DI)  is an on demand service that optimizes the use of an existing Integrated Services Digital Network (ISDN) signaling channel (D channel) to transport X.25 traffic. The X.25 D channel call is placed from the subscriber to the packet data service provider. Multilink and TCP/IP protocols are encapsulated within the X.25 logical circuit carried by the D channel. The bearer channels (B channels) use the Multilink protocol without the standard Q.922 and X.25 encapsulations, and invoke additional bandwidth as needed. AODI takes full advantage of existing packet handlers at the central office by using an existing D channel to transport the X.25 traffic. The link associated with the X.25 D channel packet connection is used as the primary link of the Multilink protocol. The D channel is a connectionless, packet oriented link between the Customer Premise Equipment (CPE) and the central office. Because the D channel is always available, it is possible to in turn offer "always available" services. On-demand functionality is achieved by using the B channels to temporarily boost data throughput and are disconnected after use.

RIF Passthru in DLSw+---Cisco AS5200 only

By default, DLSw+ terminates the RIF for Token Ring, terminates the LLC for all media types and forwards only data across a WAN with DLSw+ and TCP/IP headers. The RIF is a field in source-route bridged frames that indicates the SRB path the frame should take when traversing a Token Ring network. In the case of an explorer packet, the RIF is a field of the source-route bridged frame that indicates the SRB path that the SRB explorer has traversed so far. The RIF is limited to seven hop counts by the IBM standards. Because DLSw+ terminates the RIF at the virtual ring, the network's scalability increases because the hop count of the packet starts over, and the packet can traverse seven additional hops. Also, RIF termination simplifies network design because ring numbers no longer have to be unique throughout an entire enterprise.

However, some environments do not function properly if the RIF is terminated. For that reason, DLSw+ now supports the RIF Passthru  feature, in which the entire source-route bridged path appears in the RIF.

New Software Features in Release 11.3(2)T

The following new software enhancements are supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(2)T and later releases.

Dialer Watch

Dialer Watch  is a backup feature that integrates dial backup with routing capabilities. Previous dial backup implementations used the following conditions to trigger backup:

Previous backup implementations might not have supplied optimum performance on some networks, such as those using Frame Relay multipoint subinterfaces or Frame Relay connections that do not support end-to-end LMI.

Dialer Watch provides reliable connectivity without relying solely on defining interesting traffic to trigger outgoing calls at the central router. Dialer Watch uses the convergence times and characteristics of dynamic routing protocols. Integrating backup and routing features enables Dialer Watch to monitor every deleted route. By configuring a set of watched routes that define the primary interface, you are able to monitor and track the status of the primary interface as watched routes are added and deleted. Watched routes are monitored in the following sequence:

    1. Whenever a watched route is deleted, Dialer Watch checks to see if there is at least one valid route for any of the watched IP addresses defined.

    2. If there is no valid route, the primary line is considered down and unusable.

    3. If there is a valid route for at least one of the defined watched IP addresses, and if the route is pointing to an interface other than the backup interface configured for Dialer Watch, the primary link is considered up.

    4. In the event that the primary link goes down, Dialer Watch is immediately notified by the routing protocol and the secondary link is brought up.

    5. Once the secondary link is up, the primary link is rechecked at the expiration of each idle timeout.

    6. If the primary link remains down, the idle timer is reset indefinitely.

    7. If the primary link is up, the secondary backup link is disconnected. Additionally, a disable timer can be set to create a delay for the secondary link to disconnect after the primary link is reestablished.

DRP Server Agent Enhancements

The Direct Response Protocol (DRP) Server Agent enhancements are as follows:

E1 R2 Signaling

R2 signaling is an international signaling standard that is common to channelized E1 networks. However, there is no single signaling standard for R2. The ITU-T Q.400-Q.490 recommendation defines R2, but a number of countries and geographic regions implement R2 in entirely different ways. Cisco Systems addresses this challenge by supporting many localized implementations of R2 signaling in its Cisco IOS software.

Cisco Systems E1 R2 signaling  default is ITU, which is supported in the following countries: Denmark, Finland, Germany, Hong Kong (ITU variant), Russia (ITU variant), and South Africa (ITU variant). The expression "ITU variant" means there are multiple R2 signaling types in the specified country, but Cisco supports the ITU variant.

Cisco Systems also supports specific local variants of E1 R2 signaling in the following regions, countries, and corporations:

Argentina, Australia, Brazil, China, Columbia, Costa Rica, East Europe (includes Croatia, Russia, and Slovak Republic), Ecuador ITU, Ecuador LME, Greece, Guatemala, Hong Kong (uses the China variant), Indonesia, Israel, Korea, Malaysia, New Zealand, Paraguay, Peru, Philippines, Saudi Arabia, Singapore, South Africa (Panaftel variant), Telmex corporation (Mexico), Telnor corporation (Mexico), Thailand, Uruguay, Venezuela, and Vietnam.

MS Callback

The MS Callback  feature provides client/server callback services for Microsoft Windows 95 and Microsoft Windows NT clients. MS Callback supports the Microsoft Callback Control Protocol (MSCB). MSCB is a Microsoft proprietary protocol used by Windows 95 and Windows NT clients. MS Callback supports negotiated PPP Link Control Protocol (LCP) extensions initiated and agreed to by the Microsoft client. MS Callback is added to existing PPP Callback functionality. Therefore, if you configure your Cisco AS5100 to perform PPP Callback using Cisco IOS Release 11.3(2)T or later, MS Callback is automatically available.

MS Callback supports AAA security models using a local database or AAA server.

MSCB uses LCP callback options with suboption type 6. The Cisco MS Callback feature supports clients with a user-specified callback number and server-specified (preconfigured) callback number.

MS Callback does not affect non-Microsoft machines that implement standard PPP LCP extensions as described in RFC 1570. In this scenario, MS Callback is transparent.

PIM Version 2

Protocol-Independent Multicast (PIM) Version 2 includes the following improvements over PIM Version 1:

PIM Version 1, together with the Auto-RP feature, can perform the same tasks as the PIM Version 2 BSR. However, Auto-RP is a standalone protocol, separate from PIM Version 1, and is Cisco proprietary. PIM Version 2 is a standards track protocol in the Internet Engineering Task Force (IETF).

Cisco's PIM Version 2 implementation allows good interoperability and transition between Version 1 and Version 2. You can upgrade to PIM Version 2 incrementally. PIM Versions 1 and 2 can be configured on different routers within one network. Internally, all routers on a shared media network must run the same PIM version. Therefore, if a PIM Version 2 router detects a PIM Version 1 router, the Version 2 router downgrades itself to Version 1 until all Version 1 routers have been shut down or upgraded.

PIM uses the BSR to discover and announce RP-set information for each group prefix to all the routers in a PIM domain. This is the same function accomplished by Auto-RP, but the BSR is part of the PIM Version 2 specification. The BSR mechanism interoperates with Auto-RP.

To avoid a single point of failure, you can configure several candidate BSRs in a PIM domain. A BSR is elected among the candidate BSRs automatically; they use bootstrap messages to discover which BSR has the highest priority. This router then announces to all PIM routers in the PIM domain that it is the BSR.

Routers that are configured as candidate RPs then unicast to the BSR the group range for which they are responsible. The BSR includes this information in its bootstrap messages and disseminates it to all PIM routers in the domain. Based on this information, all routers will be able to map multicast groups to specific RPs. As long as a router is receiving the bootstrap message, it has a current RP map.

New Software Feature in Release 11.3(1)T

The following new software enhancement is supported by the Cisco AS5100 and Cisco AS5200 universal access servers in Cisco IOS Release 11.3(1)T and later releases.

SNMP Inform Requests

The SNMP Inform Requests  feature allows routers to send inform requests to SNMP managers.

Access Servers can send notifications to SNMP managers when particular events occur. For example, an agent router might send a message to a manager when the agent router experiences an error condition. SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send any acknowledgment when it receives a trap. The sender cannot determine if the trap was received. However, an SNMP manager that receives an inform request acknowledges the message with an SNMP response PDU. If the manager does not receive an inform request, it does not send a response. If the sender never receives a response, the inform request can be sent again. Thus, informs are more likely to reach their intended destination.

Because they are more reliable, informs consume more resources in the access server and in the network. Unlike a trap, which is discarded as soon as it is sent, an inform request must be held in memory until a response is received or the request times out. Also, traps are sent only once, while an inform may be retried several times.

The retries increase traffic and contribute to a higher overhead on the network. Thus, traps and inform requests provide a trade-off between reliability and resources. If it is important that the SNMP manager receives every notification, use inform requests. However, if you are concerned about traffic on your network or memory in the access server and you do not need to receive every notification, use traps.

Important Notes

The following sections contain important notes about Cisco IOS Release 11.3 T that might apply to the Cisco AS5100 and Cisco AS5200 universal access servers.

Cisco IOS Release 11.3, 11.3 NA, and 11.3 T End of Sales and End of Engineering

end of Engineering (EOE) means that there are no more regularly scheduled maintenance releases. The last maintenance release scheduled on the EOE date is only available through CCO and Field Service Operations---not through manufacturing.

EOS and EOE releases are subject to change. For the most up-to-date information on the status of EOS or EOE, see the End of Sales and End of Engineering for Cisco  IOS Software Releases product bulletins located on CCO.

For documentation of all source-route bridging commands, see the Bridging and IBM Networking Command Reference (78-4743-XX). You can also obtain the most current documentation on CCO  or on the Documentation CD-ROM.

40-bit Encryption Images Are Unavailable in Release 11.3(1)

Cisco is conducting an internal review of the build and distribution processes associated with its 40-bit Cisco IOS cryptographic products. To provide seamless access to Cisco IOS 40-bit encryption capability, Cisco will provide access to the most current 40-bit encryption images, beginning with Cisco IOS Release 11.2 (12), 11.2(12)P, and 11.3(2).

The following 40-bit encryption images are unavailable indefinitely:

This review is not related to any new or previously unreported caveats. The information gathered in the review will be used to implement new automated development and order-processing applications.

New TACACS+ Attribute-Value (AV) Pair

A new authorization feature that allows you to separately configure and authorize Multilink PPP was added in Cisco IOS Release 11.3(1). This feature can cause MLP authorization to fail in Terminal Access Controller Access Control System (TACACS+) servers that do not include authorization permissions in the configuration.

For TACACS+, add the following attribute-value (AV) pair for all users who are allowed to negotiate Multilink PPP:

service = ppp protocol = multilink {
