These release notes for the Cisco 6400 node switch processor (NSP) support Cisco IOS Release 12.0DB, up to and including Release 12.0(4)DB. These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.
For a list of the software caveats that apply to Release 12.0(4)DB, see the "Caveats" section and Caveats for Cisco IOS Release 12.0 T. The caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
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.
These release notes discuss the following topics:
The Cisco 6400 universal access concentrator (UAC) consists of an Asynchronous Transfer Mode (ATM) switching core and redundant routing engines. The ATM switch, based on Cisco Catalyst® 8500 + per flow queuing (PFQ) technology, provides the necessary ATM switching and traffic management capabilities; the router blades, derived from the Cisco 7200 router, enable the service provider to offer scalable Layer 3 services.
ATM interfaces connect the Cisco 6400 to digital subscriber line access multiplexers (DSLAMs), as well as ATM or packet cores. Because the Cisco 6400 is designed for the central office environment, it includes switch, router, and line-card redundancy, as well as 12-inch Network Equipment Business Systems (NEBS)-compliant packaging.
For information on new features and Cisco IOS commands supported by Release 12.0 T, see the "New and Changed Information" section and "Related Documentation" section.
This section describes the system requirements for Cisco IOS Release 12.0(4)DB and includes the following sections:
Table 1 describes the memory requirements for the Cisco 6400 platform supported by Cisco IOS Release 12.0 DB.
| Feature Set | Image Name | Minimum Required Flash Disk | Required Main Memory | Runs from |
|---|---|---|---|---|
Cisco 6400 | c6400s-wp-mz.120-3.DB | 3.5 MB Flash | 64 MB DRAM | RAM |
When used in a redundant configuration, the primary and backup NSPs should have identical hardware configurations, including DRAM size, Flash memory size, and Flash disk size. To learn about redundancy in the Cisco 6400, see "Configuring Redundancy and SONET APS" in the Cisco 6400 UAC Software Configuration Guide.
A Cisco 6400 NSP with Release 12.0(4)DB software requires the use of Cisco IOS Release 11.3(9)DB for the Cisco 6400 node route processor (NRP). For information about Release 11.3(9)DB for the NRP, see Release Notes for Cisco 6400 Node Route Processor (NRP) for Cisco IOS Release 11.3(9)DB.
To determine the version of Cisco IOS software currently running on the Cisco 6400 NSP, log in to the NSP and enter the show version EXEC command. The following is sample output from the show version command performed on the Cisco 6400. The version number is indicated on the second line as shown below:
Cisco Internetwork Operating System Software IOS (tm) C6400 Software (C6400S-WP-M), 12.0(4) DB .....
The output includes additional information including processor revision numbers, memory amounts, hardware IDs, and partition information. To upgrade to a new software release, see the "Cisco Connection Online" section.

The following sections list the new features supported by the Cisco 6400 in Cisco IOS Release 12.0(4)DB.
There are no new features supported by the Cisco 6400 NSP in Cisco IOS Release 12.0(4)DB.
A new DS3 node line card (NLC) has been developed for the Cisco 6400 chassis. The DS3 NLC is a half-height card that mounts in the chassis on a full-height carrier module. Coaxial interface cables are connected to the DS3 using BNC connectors on the back of the Cisco 6400 chassis. For more information about installing a DS3 NLC, see the Cisco 6400 UAC FRU Installation and Replacement guide.
There are no new features supported by the Cisco 6400 NSP in Cisco IOS Release 12.0(2)DB.
Resiliency for both the NSP and NRP is based on extended high system availability (EHSA). If the NRP fails, no virtual circuits (VCs) from the NSP must be reconfigured. The NRP blades also support online insertion and removal (OIR). When operating in non-redundant mode, the NRPs appear as separate network management entities, and can be accessed via individual console ports.
SONET APS provides a mechanism to support redundant transmission circuits, such as single-mode fibers, between SONET devices. Automatic switchover from the primary or working circuit to the backup or protection circuit happens when the working circuit fails or degrades.
The Cisco 6400 supports 1+1, linear, unidirectional, non-reverting APS operation on its redundant OC-3/STM-1 ports.
A telco uses system alarms to help monitor equipment and identify the cause of physical system problems within the central office. There are three levels of alarms: minor, major, and critical, and there are many sources of alarm conditions. Temperature thresholds are one source, but alarms can be triggered by card failure, SONET APS failures, NRP failures, and generic alarms.
The Cisco 6400 includes environmental monitoring hardware and a digital thermometer that measures the temperature of the intake air flow and the temperature at the hottest part of the chassis. Temperature thresholds for each alarm type and location are automatically set, based on empirically determined values that vary depending on the number and type of boards inserted in the chassis. In addition to the automatically set thresholds, you can set your own thresholds for minor and major temperature alarms.
The Cisco 6400 supports BellCore standard alarms, and additional commands have been added that allow you to manage the alarms and reset chassis components as needed.
The Cisco 6400 acts as a DHCP client and automatically acquires an IP address, subnet mask, and default route from a DHCP server on the network. This feature allows you to install the Cisco 6400 in the central office using non-technical personnel. The plug-n-play option allows you to configure the Cisco 6400 from a Network Operations Center (NOC), without being physically close to the system.
Web Console is a graphical user interface (GUI) lets you set or change the system configuration and monitor system activity. The Web Console application is accessible from any Web browser on the Telco management network. You can configure basic system parameters, Simple Network Management Protocol (SNMP) management parameters, set up subscribers, and monitor the current status of your chassis LEDs from anywhere on the network with Web Console.
This section contains important information about use of your Cisco 6400 UAC NSP.
For information about how to install the DS3 NLC, refer to the Cisco 6400 FRU Installation and Replacement guide available on CCO.
If you remove an OC-3 line card from a subslot and insert a DS3 line card into the same slot, the Cisco 6400 issues a warning message and refuses to bring the DS3 card online automatically. This is to prevent accidental misconfiguration of a redundant system. You can avoid the warning message if you shut down all interfaces on the NLC or NRP you want to remove before removing the card.
If you are making this card change intentionally, and a warning message is issued, use the following command to clear the warning and enable the system to bring the new line card online:
nsp# clear facility-alarm source cardtype {slot # | subslot #/#}
The LEDs on the DS3 NLC provide status and operational information about port 0 and port 1 connections. (See Table 3.)
| LED | Status | Condition |
|---|---|---|
FAIL | Steady yellow Off | DS3 NLC has failed. DS3 NLC is operational. |
PORT 0 (top connector)
RX (receive)
STATUS | Off Steady yellow Green Off Steady yellow Green Off | No traffic. Far end alarm. Receive activity. No traffic. Loss of signal. Active (primary). No power. |
PORT 1 (bottom connector)
RX (receive)
STATUS | Off Steady yellow Off Steady yellow Off | No traffic. Far end alarm. No traffic. Loss of signal. No power. |
The following commands are available for the DS3 NLC:
For more information about these commands, see the DS3 Node Line Card feature module.
Install all new NSP software images on the PCMCIA disk (disk0:) and on the NSP bootflash. The new Cisco 6400 image includes an HTML tar file with the Web Console pages and the image file.
Save your existing NSP configuration file off-line, for example on a TFTP server, before upgrading to the new image. Be sure to save the configuration that you really want to preserve; either the running configuration or the startup (NVRAM) configuration, whichever contains the most valid information.
For example, use the copy running-configuration tftp://TFTPHOST/path/name command to save the running configuration from your existing NSP onto your TFTP server.
Alternatively, you can copy the configuration onto the PCMCIA disk using the copy running-configuration disk0:my_nsp_config command.
To install the new image files, follow these steps:
| Step | Command | Task |
|---|---|---|
| 1 | copy tftp://TFTPHOST/imagename.html disk0: | Copy the Web Console tar file to the PCMCIA disk. |
| 2 | copy tftp://TFTPHOST/imagename disk0: | Copy the image file to the PCMCIA disk. |
| 3 | format bootflash: | Format the bootflash to ensure that there is enough room for the new image. (Alternatively, you can delete the oldest image and use the squeeze command to be sure that there is enough space on the bootflash for the new image.) |
| 4 | copy disk0:imagename bootflash: | Copy the image file from the PCMCIA disk to bootflash. |
For more information on the command syntax shown in this section, refer to the Cisco IOS 12.0 documentation set available on CCO. For more information on installing Web Console pages, refer to Chapter 3, "Using the Cisco 6400 Web Console Application for System Configuration" in the Cisco 6400 UAC Software Configuration Guide.
The Web Console application is designed to use JavaScript, which is available with both Netscape Navigator and Microsoft Internet Explorer. However, a number of issues are present when using either application. To date, using Netscape Navigator 4.x has resulted in fewer issues than Microsoft Internet Explorer 4.x.
Before using the Web Console application, verify that your browser is set to use at least 4 MB (4096 KB) of cache memory.
The following sections tell how to deal with some of the browser issues affecting each application.
Web Console might not reflect the most current redundancy status and auto synchronization setting because the check box and option buttons are not displayed properly. Therefore, you must verify your configuration by viewing the configuration file.
An empty dialog box might display after you apply new settings in any of the Web Console pages. If an empty dialog box is displayed, click the Internet Explorer Refresh button to view your new settings.
The show interface command on the Status page fails with Internet Explorer. There is no workaround, so this function is not available.
If a blank window is displayed after you resize your Navigator window, click the Reload button to redisplay the page.
Frequent and rapid clicking on the Web Console Status page can cause syntax and LED errors. This problem is eliminated if the browser cache is set to 4096 KB.
On a dual-NSP system, switchovers can occur if verbose debugging commands, such as debug all or debug oir commands, are used. To avoid this situation when using verbose debug commands, execute the redundancy keepalive disable command at the EXEC prompt prior to turning on the debug command. After debugging is disabled, enter the redundancy keepalive enable command to restore normal system operation.
This section contains open and resolved caveats for the current Cisco 6400 NSP IOS release only.
Caveats in Cisco IOS Release 12.0(4)T also apply to Release 12.0(4)DB. For information on caveats in the Cisco IOS Release 12.0(4)T, refer to the "Caveats" sections in the Cross-Platform Release Notes for Cisco IOS Release 12.0 located on CCO and the Documentation CD-ROM. This section contains caveats affecting all maintenance releases.
This section describes possibly unexpected behavior by Release 12.0(4)DB.This section describes severity 1, 2, and selected severity 3 caveats.
There are no caveats resolved in Release 12.0(4) DB.
