Issue/Introduction

You are receiving the below message for several of our Broadcom products:

CAS9182A - WARNING: LMP key Prod (xx) xxxxxxxxxx  expires in 018 days.

You notice that the LMP Key shows a DATE that does not coincide with this warning message.

Is there a Grace Period, is CAS9182A accounting for a Grace Period ? When will the products fail to function ?

Resolution

The LMP key DATE on the KEY is basically a comment.  The actual date of expiration is  calculated by CAIRIM based on the encoded date on the key and logic that ensures the expiration does not occur on a weekend. It is usually on the Tues following the encoded date, but can be longer. 

 

• Take the following key as an example:

Prod(KO) Date(12SEP27) CPU(*SITE*-/########) LMPCODE(################)

It shows the expiration date of Sept 12 of 2027.  The actual expiration date is:  Sept 21 2027.

 

• The expiration date can be verified via command CAIRIMU PROD(KO): [command is valid for CCS r12 and above]

 Prod (KO) viols|warns/stat(000/N) Warnstart(Sun, 22-Aug-2027)
 Expiry1(Tue, 21-Sep-2027) Expiry2(Tue, 21-Sep-2027)
 Product name(TOP-SECRET      )           

The true expiration date is detailed under Expiry2:

Expiry1 and Expiry2 were originally provided to support grace periods, but the current policy is 0 days grace since product functionality is unaffected by an expired or missing key.

Note: The Product Name will only be shown if running CCS 15.0 with LU04507 implemented.

 

• In general, license keys are generated with a default warning period of 30 days. Therefore, 30 days prior to the expiration date you will begin to notice CAS9182A messages. The number of days shown on this message will decrease until the expiration date is reached. At that time you will receive CAS9180E messages (CAS9181A messages on weekends) indicating a valid license key is no longer present on the system for the mentioned product. Product functionality will continue uninterrupted despite the messages. You should contact Broadcom licensing or our Broadcom account representative for valid license keys.
