These release notes describe features and caveats for the Cisco 6400 universal access concentrator (UAC) node switch processor (NSP) with Cisco IOS Release 12.0(1) DB.
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(1)T, refer to the "Caveats" section of this document.
These release notes discuss the following topics:
The Cisco 6400 is a new system consisting of an Asynchronous Transfer Mode (ATM) switching core and redundant routing engines. The ATM switch, based on 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 NEBS-compliant packaging.
This section describes the system requirements for Release 12.0(1) 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 | c6400-wp-mz | 3.5 MB Flash | 64 MB DRAM | RAM |
To determine the version of Cisco IOS software currently running on the Cisco 6400, log in to the NSP and use 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(1) DB .....
Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.
For information on updating a dual-NSP system to a new software release, refer to Chapter 5, "Configuring Redundancy and SONET APS" of the Cisco 6400 UAC Software Configuration Guide.
For information on updating a single NSP system to a new software release, refer to the Cisco IOS Software Release Upgrade Paths and Packaging Simplification product bulletin located on CCO. On CCO, follow this path: Products and Ordering: More Information: Product Bulletins. Scroll to Software. Under Cisco IOS 12.0, click the Upgrade Paths bulletin.
The Cisco IOS software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. The Cisco 6400 can only use a single image called c6400-wp-mz.

This section lists new features introduced for the Cisco 6400 in Cisco IOS Release 12.0(1) DB. For more information about these features, refer to the Cisco 6400 Software Configuration Guide located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Resiliency for both the NSP and NRP is based on extended high system availability (EHSA). If the NRP fails, no 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 automatic protection switching (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 airflow 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. Because the plug-n-play option allows you to configure the Cisco 6400 from a Network Operations Center (NOC).
Web Console is a graphical user interface (GUI) used to 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, 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.
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.
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: | Formats 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 Explore. 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 caveats for the current Cisco 6400 IOS release only.
Caveats in Cisco IOS Release 12.0(1) also apply to Release 12.0(1) DB. For information on caveats in the Cisco IOS Release 12.0(1), refer to the "Caveats" section in the Cross-Platform Release Notes for Cisco IOS Release 12.0 document 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(1)DB. This section describes only severity 1 and 2 caveats.
Step 1 On the NLCs that you want to make non-redundant, shut down all interfaces.
Step 2 Remove the redundant pair of cards from their slots.
Step 3 From the NSP configuration mode, remove the redundancy configuration for the interfaces, as shown in the following example:
Switch# conf t
Switch(config)# redundancy
Switch(config-r)#no associate subslot 5/1 6/1
Switch(config-r-a-su)#end
Step 4 Reinsert both NLCs in the chassis.
Switch(config-r)#associate subslot 5/1 instead of Switch(config-r)#associate subslot 5/1 6/1. You must specify both subslot parameters when using this command.Because Cisco IOS Release 12.0(1) DB is the first version of Release 12.0 DB, only the initial caveats are documented in these release notes. A list of any resolved caveats will be documented beginning in the next version of these release notes.
