Release Notes for Cisco AS5300 for Cisco  IOS Release  12.0(2)XD

Release Notes for Cisco AS5300 for Cisco  IOS Release  12.0(2)XD

December 7, 1998

These release notes describe new features for the Cisco  AS5300 universal access server that support Cisco  IOS Release 12.0(2)XD. Cisco IOS Release 12.0(2)XD is based on Cisco IOS Release 12.0(2)T.

Use these release notes in conjunction with the cross-platform Release Notes for Cisco IOS Release 12.0 T located on Cisco Connection Online (CCO) and the Documentation CD-ROM.

For a list of software caveats that apply to Release 12.0(2)XD, refer to the "Caveats" section.

Contents

These release notes discuss 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 today's analog dial access services to tomorrow's digital dial access services.

System Requirements

This section describes system requirements for Release 12.0(2)XD and includes the following sections:

Memory Requirements

Table 1 describes the memory requirements of the Cisco IOS feature sets for the Cisco  AS5300 access servers for Release 12.0(2)XD. Flash memory is optional for the Cisco  AS5300 images.

Determining Your Cisco IOS Software Release

To determine the version of Cisco IOS software currently running on your access server, log in to the Cisco AS5300 and enter the show version EXEC command:

router> show version

An output begins similar to the following. The Cisco IOS version appears in the second line.

Cisco Internetwork Operating System Software 
IOS (tm) 5300 Software (C5300-JS-M), Version 12.0(2)XD.......

Additional command output includes more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

Upgrading to a New Release

At the time of this printing, no product bulletins are available for upgrading to Cisco IOS Release 12.0 T. For generic information on upgrading to a new software release, refer to the Cisco IOS Software Release Upgrade Paths and Packaging Simplification  product bulletin located on CCO.

Products & Ordering: More Information: Product Bulletins. Scroll to Software. Under Cisco IOS 11.3, click the Upgrade Paths bulletin. The Cisco IOS Software Release Upgrade Paths and Packaging Simplification bulletin does not contain information specific to Cisco IOS Release 12.0  T, but provides generic upgrade information that might apply to Cisco IOS Release 12.0  T.

Modem Code

Cisco IOS Release 12.0 and later includes bundled modem code, which is the firmware or portware that runs on the MICA 12-port, Microcom 12-port, or MICA 6-port modem cards. Modem code is bundled with the Cisco IOS software image to eliminate the need to store separate modem code. When the access server starts, the Cisco IOS software unpacks the modem code and loads the proper code on the modem cards. Table 3 lists bundled modem code versions.

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


Note The Cisco factory could have installed a later version of modem code than the one bundled with the Cisco IOS software. The factory installs modem code in Flash memory and maps that code to the modems.

To understand how Cisco IOS software uses Microcom modem code, see the section "Modem Code" in the Installing 56K 12-Port Modem Modules in Cisco  AS5300 Universal Access Servers publication. To understand how Cisco IOS software uses Mica modem code, see the section "Modem Code" in the Installing 6-Port Modules and Carrier Cards in  Cisco AS5300 Universal Access Servers publication.

New and Changed Information

This section lists new features available for the Cisco AS5300 in Cisco IOS Release 12.0(2)XD and the Cisco IOS Release 12.0(1)T software. To locate the online documentation about these features, refer to the "Feature Modules" section.

New Features in Cisco IOS Release 12.0(2)XD

The following new features are available for the Cisco AS5300 in Cisco IOS Release 12.0(2)XD.

8 E1/T1 and 240 Modem Upgrade

This doubles the density of the AS5300 from 4 to 8 E1/T1s plus 4 T serial interfaces and 240 modems. There is a new Octal PRI card and a new Amazon II modem card with DMM modems. The software contains new drivers for the serial interfaces, E1/T1, firmware for the new Framer chips, and general upscaling for the interfaces.

New Feature Boards Supported

The following feature boards are supported in the Cisco IOS Release 12.0(2)XD:

New Features in Cisco IOS Release 12.0(1)T

The following new features are available for the Cisco AS5300 in Cisco IOS Release 12.0(1)T. To locate the online documentation about these features, refer to the "Feature Modules" section.

CLI String Search

The Command Line Interface (CLI) String Search feature allows you to search or filter the output of any show or more command. This is useful when you need to sort though large amounts of output or if you want to exclude output that you do not need to see. CLI String Search also allows for searching and filtering at --More-- paging prompts.

With the search function, you can begin unfiltered output at the first line that contains a regular expression you specify. You can specify a maximum of one filter per command to either include or exclude output lines that contain the specified regular expression.

A regular expression is any word, phrase, number, or other type of information that appears in show or more command output.

Easy IP Phase 2-DHCP Server

With the introduction of Easy IP Phase 2, Cisco IOS software also supports Intelligent DHCP Relay functionality. A DHCP Relay Agent is any host that forwards DHCP packets between clients and servers. A DHCP Relay Agent enables the client and server to reside on separate subnets. If the Cisco IOS DHCP server cannot satisfy a DHCP request from its own database, it can forward the DHCP request to one or more secondary DHCP servers defined by the network administrator using standard Cisco IOS IP helper-address functionality.

ISDN MIB RFC 2127

The new Integrated Services Digital Network (ISDN) Management Information Base (MIB) RFC 2127 has been designed to provide useful information in accordance with the IETF's new standard for the management of ISDN interfaces. It controls all aspects of ISDN interfaces. RFC 2127 provides information on the physical Basic Rate Interfaces (BRIs), control and statistical information for B (bearer) and D (signaling) channels, terminal endpoints, and directory numbers.

The ISDN MIB RFC 2127 controls all aspects of ISDN interfaces. It consists of five groups:

The ISDN MIB RFC 2127 enables you to use any commercial SNMP network management application to support ISDN call processing in Cisco IOS software. You can integrate management of dial access products using ISDN with your existing network management systems.

Time-Based Access Lists

It is now possible to implement access lists based on the time of day. To do so, create a time range that defines specific times of the day and week. The time range is identified by a name, and then referenced by a function, so that those time restrictions are imposed on the function itself.

Currently, IP and IPX extended access lists are the only functions that can use time ranges. The time range allows the network administrator to define when the permit or deny statements in the access list are in effect. Prior to this feature, access list statements were continuously in effect after they had been applied. Both named or numbered access lists can reference a time range.

Caveats

This section contains the open caveats for the current Cisco IOS maintenance release only. The software caveats are also located in the Caveats for Cisco IOS Release 12.0 T document that accompanies these release notes.The caveats document is located on CCO and the Documentation CD-ROM.


Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. Bug Navigator II is at http://www.cisco.com/support/bugtools, or from CCO, select Software & Support: Technical Tools: Bug Toolkit II

Open Caveats - Release 12.0(2)XD

This section describes possibly unexpected behavior by Release 12.0(2)XD. Unless otherwise noted, these caveats apply to all 12.0 releases up to and including 12.0(2)XD.

Basic System Services

Configuring the layer3 switching with access filter in and out on the hssi interface with the Frame relay ietf encap, then try to configure the smds encap will cause the router to crash.
When configuring a mc3810 for CCS cross-connect, it's possible that calls will stop getting connected after a period of time.

DECnet

This problem is specific to the RSM platform and for DECnet over VLANs.
The code for DECnet support over VLANs uses a cache to store VLAN-header information, and this cache is used in the fast-switch path.
When there is a routing topology change, the fast-switching code continues to look at the stale cache entry, and as a result, packets destined via the new route end up getting black-holed.
The work-around is to disable DECnet fast-switching on the relevant interface.

IBM Connectivity

Router running DLSw with FST/Direct/LLC2(Lite) encapsulations could crash.
Workaround for this is to use DLSw with TCP encapsulation.

Interfaces and Bridging

FDDI PA will now have a software address filter at VIP level to filter out unwanted multicast packets. This helps performance and also unnecessary entries in netflow tables.
If "no keepalive" (or 0 keepalive) is configured on fastethernet, the line will stay up even though the MII is removed or the cable is disconnected. If the interface is then reconfigured with "keepalive" (of non-zero value) while the physical media stayed down, the link would still indicate up. The only workaround is by doing a shut/no shut, or clear interface command.
A large packet sent over a MLP bundle of over 2 links with VPDN on a ATM PPP tunnel on a ATM-Lite interface will be corrupted sometimes. A workaround is to disable the fastswitching on the ATM-lite interface.

IP Routing Protocols

If ospf has both an external and a summary route to the same network and a partial spf run deletes the summary route, the external route will not be installed.
The external LSA may have the routing bit set, even if it is not installed in the routing table. This is caused by a failure to reset the external's routing bit when the summary route replaces the external route in the ip routing table. The following sequence of events illustrates the problem, given external and summary routes to network 1.0.0.0:
1. ospf installs external route to 1.0.0.0. The external LSA for 1.0.0.0 has its routing bit set 2. ospf installs summary route to 1.0.0.0, replacing the external route. The routing bit is not reset on the external LSA for 1.0.0.0. 3. ospf performs a partial spf to remove the summary route to 1.0.0.0. The external route to 1.0.0.0 is not installed. To add to the confusion, the routing bit is still set on the external LSA for 1.0.0.0.
A'clear ip route *' will force the installation of the external route. Alternatively, a'clear ip ospf redist' at the router that originates the external route will trigger installation of the external route.
Guaranteed service flowspec in RSVP RESV messages must contain certain fields within a certain range (as indicated by RFC 2212). This fix puts these checks in the code
With sync and certain topologies, some bgp routes may not get advertised after peer reset.
The workaround is to configure "no sync", or "clear ip bgp x.x.x.x".

ISO CLNS

On all platforms which do not use the old mci controller, fast-switching of clns traffic with non-zero N-Selector does not work.

Miscellaneous

When running 2523 and 2524 serial ports in asynchronous mode, modem control is only supported when using DTE style 5-in-1 cables (in order to connect to DCE devices). The DCE 5-in-1 cable (in order to connect to DTE devices) will not support modem control for the asynchronous mode. In order to support DTE devices with modem control, it is required to use the DTE style cables with a null modem adapter.
When you configure Bisync (encapsulation bstun) with the ASCII character set (bsc char-set ascii) on the first port of a serial WIC (1T, 2T, or 2A/S) in WIC slot 0 of a Cisco 2600 series router, only the first character of each frame is received, and the BSTUN tunnel is not established. This only affects Bisync mode when it is configured with the ASCII character set. Other encapsulations are not affected, and using the EBCDIC character set with Bisync works correctly.
For the first serial port in WIC slot 0, the parity detection is not configured correctly for Bisync in ASCII mode. The first character of each frame generates a parity error that causes the receiver to discard the frame after the first character received.
Workaround: Use a different serial port: either the second serial port (port 1) on a 2T or 2A/S WIC in WIC slot 0 or any serial port in WIC slot 1. If you have only one serial WIC, moving it from WIC slot 0 to WIC slot 1 fixes this problem.
When running Tag Switching and CEF on an Ethernet interface, it is possible for the interface to get into a state where the IP packets are not forwarded properly.
The problem occurs when a CEF entry is improperly pointing at a Tag data structure. To check whether this is the problem, do
show adjacency detail
for the next hop on the failing route. In the failure case, the packet counts on the "IP" adjacency will not be increasing, but those on the "TAG" one will.
Workaround: disable Tag switching on the interface
When enrolling certificate with Entrust VPN, you might fail to get CA certificates. So far, this problem only happened on the Cisco 2500 platform and there is no work around. Please upgrade to the next build.
In Release 11.2P and 11.3 when Fast Ethernet subinterfaces are configured for encryption, if the crypto map is only applied to the main interface and the IP address is configured in the subinterface, the packets could be switched in the clear. In Release 12.0, enabling CEF could cause the packets to get dropped.
When you run TRISL to a Cisco 7000 family router, some frames larger than 1535 bytes might not be forwarded. This condition occurs when you run TRISL between two VLANs that are on switches.
Workaround: Do not use TRISL. Use an external device to router or bridge between the two different VLANs. Or modify the end devices so that they do not send packets larger than 1500 bytes.
From enclosure: Release-note
A Cisco 1600 router or Cisco 3600 series router will reload when IPSEC is configured over the ISDN link. This condition is caused by the IP route-cache that is enabled by default on all interfaces.
The workaround is to turn off fast switching with the no ip route-cache command on the ISDN interfaces.
From enclosure: Release-note-2
This crash has also been seen on the 3600 platform.
If a UDP packet with an invalid length is sent to port 514 (the "syslog" port) on an IOS device, the device is likely to crash, possibly without saving a stack trace. Such packets are sent by the popular "nmap" port scanning program.

Wide-Area Networking

StatusMsg with endpointRef is not processed in multipoint state table. This could result in releasing multipoint vc.

Resolved Caveats - Release 12.0 T

All the caveats listed in this section are resolved in release 12.0(2)T.

IP Routing Protocols

workaround:
The workaround is to configure "router rip" on the router first, before configuring the address on the interface.

Miscellaneous

RADIUS accounting does not work if you have separate authentication and accounting servers.
An IP client might not be able to ping the Route Switch Module (RSM). This situation might occur during Token-Ring Virtual LAN (TR VLAN) configuration on the RSM. It is most common when the IP client sends an address resolution protocol (ARP) without a routing information field (RIF), then sends an ARP with a RIF. The situation might also occur if the concentrator relay function (CRF), to which the client is connected, is configured for source-route bridging (SRB). Workaround: Change the CRF mode from SRB to source-route transparent (SRT) bridging.

Novell IPX, XNS, and Apollo Domain

The Internetwork Packet Exchange (IPX) input process might run out of stack, causing a system reload or reduced performance. There is no workaround.
