Introduction
This section contains information about the Cisco AS5800 universal access servers and Early Deployment (ED) Releases for the Cisco AS5800.
Cisco AS5800
The Cisco AS5800 is a high-density, Integrated Services Digital Network (ISDN) and modem Wide Area Network (WAN) aggregation system that provides digital and analog call termination. It is intended to be used as a service provider dial point-of-presence (POP) or centralized enterprise dial gateway. The Cisco AS5800 consists of a dial shelf, a router shelf, and (optionally) a system controller:
•
•
•
The Cisco 5814 dial shelf and host Cisco 7206 router shelf communicate over a a dial shelf interconnect cable (DSIC). This nonblocking interconnect supports 10 Mbps, full-duplex data transfer. Data is converted into packets by the feature cards, transmitted to a hub on the dial shelf controller (DSC) card, and from there sent to the router shelf. Conversely, packets from the router shelf are sent to the DSC card, where they are transmitted over the backplane to the modem and trunk cards.
The AC-input power shelf is an optional component of the Cisco AS5800 universal access servers and is used to convert AC-input power into DC-output power for the DC-powered Cisco 5814 dial shelf. The AC-input power shelf contains two AC-input power supplies.
The Cisco AS5800 universal access servers accept AC-input power via a separate, self-contained AC-input power shelf, which converts AC-input power into DC-output for use by the DC-powered dial shelf. The AC-input power shelf is rack-mounted and has a safety cover that shields the electrical connections in the power shelf rear.
The AC-input to DC-output connection supplies -48V DC-output power to the dial shelf power entry modules (PEMs). The PEMs receive the -48 volts and transmit power to the filter module. Power flows through the filter module to the backplane where it is distributed to the dial shelf controller card(s) and feature cards.
The AC-input power shelf includes two 2,000-watt, AC-input power supplies that plug into a common power backplane in the AC-input power shelf. A single AC-input power supply is capable of powering a fully configured Cisco 5814 dial shelf. The second power supply provides full redundancy.
For more information on the Cisco AS5800, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-5800-SICG) or the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-5800-HICG) that shipped with your system.
For information on new features and Cisco IOS commands supported by Release 12.0 XJ, see the "New and Changed Information" section and "Related Documentation" section.

Determining the Version of Your Software Release
To determine the version of Cisco IOS software running on your Cisco AS5800, log in to the Cisco AS5800 and enter the show version EXEC command:
router>show versionCisco Internetwork Operating System SoftwareIOS (tm) AS5800 Software c5800-p4-mz, Version 12.0(4) XJ6, RELEASE SOFTWAREUpgrading to a New Software Release
For information on upgrading to a new software release, see the product bulletin Cisco IOS Software Release 12.0 T Upgrade Paths and Packaging Simplification (#819: 1/99) on CCO at:
Service & Support: Product Bulletins: Software
Under Cisco IOS 12.0, click Cisco IOS Software Release 12.0 T Upgrade (#819: 1/99).
Modem Code Software
Modem code is either stored in Flash memory or bundled in the Cisco IOS software image. Bundling eliminates the need to store separate modem code images. When the Cisco AS5800 is powered on, the system software unpacks the modem code and loads the proper code on the modem cards.
The show modem mapping 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 modem mapping command to help you decide if you need to update your modem code files.
Note
The modem code release notes are on CCO and the Documentation CD-ROM:

Important Notes
The following section contains important notes about Cisco IOS Release 12.0(4) XJ6 that can apply to the Cisco AS5800.
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
This section only contains open and resolved caveats for the current Cisco IOS maintenance release.
All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0 XJ.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0.
For information on caveats in Cisco IOS Release 12.0 T, see Caveats for Cisco IOS Release 12.0 T, which lists severity 1 and 2 caveats and select severity 3 caveats and is located on CCO and the Documentation CD-ROM.
Note
Open Caveats—Release 12.0(4) XJ6
This section describes possibly unexpected behavior by Release 12.0(4) XJ6 and describes only severity 1 and 2 caveats:
Basic System Services
•
The following cli command does not function : snmp-server packetsize.
The maximum snmp packetsize for 12.0(3)T is fixed at 484. There is no known workaround.
Miscellaneous
•
Reusing the same CE address on two CEs connected to the same PE, in different VRFs, does not work properly in the case where the link between the PE and CE is ethernet.
Wide-Area Networking
•
Entering commands "shut" and "no shut" quickly on an AS5800 E1 controller while digital ISDN traffic is running will cause other D-channels to go down also. It does not occur on T1 or T3 controller, and does not occur with modem ISDN. This problem may cause unwanted errors for customers who run test script to evaluate our product. A workaround is to wait 30 to 45 seconds between shut and no shut.
•
By default, LANE FSSRP is now completely off on all subinterfaces and all LANE components.
To turn this feature on, the interface config command: lane fssrp
should be used. Once entered, this command recycles all LANE components on that interface and hence its subinterfaces.
Resolved Caveats—Release 12.0(4) XJ6
All the caveats listed in this section are resolved in release 12.0(4)XJ5.
Miscellaneous
•
When the dial shelf is reloaded on an AS5800 that is configured to download non-bundled portware calls are accepted at startup time which subsequently get dropped. The problem occurs as follows:
1. A dial shelf is reloaded. The modem feature boards are configured to auto-boot.
2. IOS downloads the default bundled portware to all modems.
3. All modems show ready and available.
4. IOS resets the first modem card to prepare to download the non-bundled portware.
5. A call comes in and is connected to an available modem on the next modem card since the first is out of service.
6. The first modem card downloads the non-bundled, non-default portware to all of the modems on that card and becomes available to take calls.
7. All the modems in the second card are reset to prepare to download the non-bundled portware. Any calls that were active on that modem are disconnected at this time.
•
5800 with 32M runs out of memory with WFQ turned on on all interfaces in the box.
•
After an extended stress test, memory allocation errors began to occur when using the store-and-forward fax offramp. There is no known workaround at this time.
•
L2TP tunnels between 5300s and the 7200 are dropping several times every hour.
•
When the gateway receives large files from the external mail client, the smtp connection timer must be stopped to avoid timeout. The timer is now stopped correctly.
•
The fax store-and-forward off-ramp router smtp server does not clean-up some sessions resulting in memory loss.
The problem is unmasked by the fix for CSCdm37111. Before this fix the problem existed but would not manifest itself in any severe way.
•
On an AS5800 running 12.0(4.3)T, the dialup modem peers are unable to transmit full-sized (1500-byte) PPP packets to their destination. "show modem op" shows that the PPP packets are being successfully received by the MICA modems without error (parameters 33 and 35.) However, "show interface" on the corresponding async interfaces, shows that NO IP packets are being received - either good or errored.
If the peer transmits a 1499 byte packet (ping -l 1457 from a PC), then they are transmitted successfully.
Workaround: reconfigure the PPP peer to use an MTU below 1500B—perhaps 576B. On a Windows PC, this can be done via registry settings. See the following Web site:
http://www.cisco.com/warp/public/105/38.shtml
•
A NAS configured with multiple dialer profiles cannot send a packet back to the initiating client when the bind of the dialer profile is done at authentication.
•
Crash in onramp after about 24 hours of stress traffic. Seems related to the fact that destination mail server was not responding.
Wide-Area Networking
•
If distinct dialer maps to different destinations share the same remote name, traffic will fail to pass on the 2nd and subsequent sessions.
This ability is implemented in 12.0T as a hidden command. dialer mult-map-same-name allows 2 users to dial in to the dialer with the same ppp user_name. It's behavior with other dialer features is currently unpredictable and should be used with caution.
