Release Notes for Cisco 6400 NSP for Cisco IOS Release 12.1(3) DB
February 14, 2002
Note
You can find the most current Cisco IOS documentation on Cisco Connection Online (CCO). The electronic documents might contain updates and modifications made after the hardcopy documents were printed.
These release notes for the Cisco 6400 node switch processor (NSP) describe the enhancements provided in Cisco IOS Release 12.1(3) DB1. These release notes are updated as needed.
For a list of the software caveats that apply to Release 12.1(3) DB1, see the "Preexisting NSP Hardware Caveats" section and Caveats for Cisco IOS Release 12.1 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 12.1 located on Cisco Connection Online (CCO) and the Documentation CD-ROM.Contents
These release notes describe the following topics:
•
System Requirements
This section describes the system requirements for Cisco IOS Release 12.1(3) DB1:

Memory Recommendations
Hardware Supported
Cisco IOS Release 12.1(3) DB1 supports the Cisco 6400 NSP and the NSP with Stratum 3/BITS (NSP-S3B). The NSP-S3B, otherwise identical to the NSP, is required to use the Building Integrated Timing Supply (BITS) Network Clocking software feature.
Software Compatibility
Cisco recommends that Cisco IOS Release 12.1(3) DB1 be used concurrently with Cisco IOS Release 12.1(3) DC for the Cisco 6400 node route processor (NRP). For information about Release 12.1(3) DC for the NRP, see the Release Notes for Cisco 6400 Node Route Processor (NRP) for Cisco IOS Release 12.1(3) DC.
Determining the Software Version
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:
Router> show versionCisco Internetwork Operating System SoftwareIOS (tm) C6400 Software (C6400S-WP-M), Version 12.1(3) DB1, EARLY DEPLOYMENTRELEASE SOFTWARE (fc1)The output includes additional information including processor revision numbers, memory amounts, hardware IDs, and partition information.
Upgrading to a New Software Release

Important Notes
The following sections contain important information about the use of your Cisco 6400 UAC NSP.
Web Console Issues
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.
Microsoft Internet Explorer 4.x
Web Console might not reflect the most current redundancy status and autosynchronization 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.
Netscape Navigator 4.x
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.
ATM Generic Flow Control Field
When an ATM cell is received on the NSP, the generic flow control (GFC) field of the ATM cell is passed without modification to the outbound virtual circuit. This is not compliant with the ATM Forum UNI specification, version 3.1, which requires all bits of the GCF field to be reset to zero.
Using Verbose Debug Options
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.
Software Caveats
Caveats describe unexpected behavior in the Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. This section contains open caveats for the current Cisco 6400 NSP IOS release only.
Caveats in Cisco IOS Release 12.1 T also apply to Release 12.1 DB. For information on caveats in Cisco IOS Release 12.1 T, see Caveats for Cisco IOS Release 12.1 T located on CCO and the Documentation CD-ROM.
Note
Open Caveats—Release 12.1(3) DB1
There are no open caveats in Cisco IOS Release 12.1(3) DB1.
Closed and Resolved Caveats—Release 12.1(3) DB1
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(3) DB1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

Open Caveats—Release 12.1(3) DB
There are no open caveats in Cisco IOS Release 12.1(3) DB.
Closed and Resolved Caveats—Release 12.1(3) DB
There are no closed and resolved caveats in Cisco IOS Release 12.1(3) DB.
Open Caveats—Release 12.1(1) DB1
There are no open caveats in Cisco IOS Release 12.1(1) DB1.
Closed and Resolved Caveats—Release 12.1(1) DB1
This section describes caveats that have been closed and resolved in Cisco IOS Release 12.1(1) DB1.
•
During the NRP boot/initialization cycle, memory may be allocated to the Point-to-Point Protocol (PPP) process. This memory may be held onto for a long time, while subsequent system attempts to acquire additional memory fail resulting in messages that indicate that malloc failed.
This behavior occurs due to a lock in an internal communication path between the NRP and the NSP. Messages back up on the NRP and are never transmitted to the NSP. The response of these messages is required to free the memory held by the PPP process.
To detect the locked-up communication path, execute the show buffers command on the NRP. If the section "PAM Mbox Pak buffers" shows a value with more buffers than the maximum allowed and that value is growing, the lock condition has occurred. There is no workaround.
Preexisting NSP Hardware Caveats
This section describes possible unexpected behavior by earlier hardware versions of the NSP. To determine your NSP part number (P/N) and hardware version, see the section "Determining Your NSP Part Number and Hardware Version" on page 9.
•
Affected Part Number:
800-03785-03Symptom:
While the NSP is in Slot 0A of a single NSP system, the NRPs reset during NSP reloads or resets.Workaround:
In a nonredundant system using an NSP of P/N 800-03785-03, place the NSP in Slot 0B.•
Affected Part Number:
800-03785-03Symptom:
The system remains at the ROMMON prompt after a crash instead of rebooting automatically.Workaround:
To prevent this problem, set the config register boot field to 0x2.If the workaround does not work, replace the NSP with P/N 800-03785-04 or higher.
•
A small percentage of NSPs might experience dropped cells. To determine if your NSP is affected, use the show controllers atm 0/0/0 EXEC command and check the values in the TPE column.
This field counts the number of transmit parity errors and should display all zeros for a good system. If a non-zero value is displayed in the TPE column, replace the NSP with P/N 800-03785-05 or higher.
•
Affected Part Numbers:
800-03785-03 (without Deviation D99-3628), 800-03785-04, 800-03785-05Symptoms:
The NSP's network management Ethernet (NME) interface might lock up and require a reset with a "shut" and "no shut" sequence or a complete board reset.The NSP might crash with a "Write Exception," "Bus Exception," or "System Reserved Exception" error message.
Because these symptoms might be caused by other problems, use the following table to determine the likelihood of this particular problem:
Workaround:
If you experience this problem, replace your NSP with P/N 800-03785-06 or higher, or with P/N 800-03785-03 with deviation sticker D99-3628 applied.•
Affected Part Numbers:
800-03785-01, 800-03785-02, 800-03785-03, 800-03785-04, 800-03785-05, 800-03785-06, 800-03785-07Symptom:
NSP reports unknown cardtype when the chassis is populated primarily with NRPs.Workaround (use one of the following):
