Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Problem Description

The new hardware (HW) version of the 15454-M-WSE-K9 product will not be compatible with software releases earlier than 12.0.1 and will display a FPGA version mismatch alarm.

Background

The 15454-M-WSE-K9 product will be released with a HW version to address the supply continuity issue of a microprocessor component. The new processor version is compatible with the latest FPGA version 0x36 onwards.

Software releases earlier than 12.0.1 do not have the relevant FPGA version (0x36) as part of the software package and consequently a mismatch alarm is displayed. However, there is no functional impact.

Problem Symptom

Due to the incompatibility of the FPGA version with software releases earlier than 12.0.1, the customer will see an FPGA version mismatch alarm, "Traffic Affecting Reset Required".

The alarm will persist even if an FPGA upgrade is triggered using Cisco Transport Controller (CTC), or the FPGA upgrade process shows complete.

The existing software will reject writing the FPGA image in the software package and the unit will hard reboot, which will impact traffic.

For an example of an FPGA version mismatch alarm, which is a per-card alarm, see this image:

Workaround/Solution

There is currently not a workaround. No action is required and you can ignore the "Traffic Affecting Reset Required" alarm.

However, in order to avoid this alarm, Cisco recommends that you upgrade to Software Release 12.0.1 or later which will be available in June 2020. The download link will be updated once the Software Release is available.

How To Identify Affected Products

Option 1. IDPROM Display

When a unit with a software release earlier than 12.0.1 displays the "Traffic Affecting Reset Required" alarm, check the HW type in the IDPROM display. In the case of new HW, the alarm can be ignored.

In order to identify a new board, enter the idpromDisplay command. The new HW Part Number should be 800-xxxxx-03 or higher and the HW Revision will start from A0 onwards. An example of the IDPROM display is shown here:

-> idpromDisplay
HW Part Number [ddd-ddddd-dd]: - 800-39163-03
HW Revision [alphanum (2)]: - A0
Card serial number [alphanum(11)]: - CATXXXXXXXX
Card Name [string]: - WSE-L-K9
CLEI Code [alphanum(10)]: - WOWUA8XXXX
Equipment ID [hhhh]: - 2825
Application filename [string]: - WSE.BIN
Extended Information [string]: -
Hardware Revision [ddd.ddd]: - 0.0
New Deviation Number [Ddddddd]: - D553954
Fab Version [dd]: - 03
Version Identifier [Vdd ]: - V03
Product Number [string]: - 15454-M-WSE-L-K9
