Switch Engine License Expiry Warnings
Switch Engine logs warning messages when a Subscription license is approaching expiration or has expired. These messages help network administrators take action before Premier features become unavailable.
When Time Remaining < 15 Days
Switch Engine logs daily Error-level EMS messages:
Sep 13 15:42:29 5720-48MXW-SwitchEngine <Erro:licMgr.FeatTimeExpSoon>
(licMgrServer.c:1394) License product STANDARD for the Standard feature
will expire in 14 day(s) - the license will expire soon.
Note
In Switch Engine 34.1 and later, this message is updated to:
Jul 18 12:20:50.52 DUT2 Erro:licMgr.FeatTimeExpSoon Switch:
(disableExpiredFeature@licMgrServer.c:1419) License check of product
STANDARD for the Standard feature failed, license assignment will expire
in 13 day(s).
When License Fully Expires
After the expiration date is reached and Premier features are disabled:
Sep 27 21:52:23 5720-48MXW-SwitchEngine <Crit:licMgr.FeatTimeExp>
(licMgrServer.c:1384) License product STANDARD for the Standard feature
has expired.
When Switch Reboots After Expiry (Grace Period)
If a switch initializes (reboots) after the subscription expires and lacks cloud connectivity, it enters a 60-minute grace period:
Jul 29 12:54:14 5720-48MXW-SwitchEngine <Crit:licMgr.FeatTimeExpExtnd>
(licMgrServer.c:1387) The STANDARD license has expired due to lack of
connectivity. The Standard features will become unavailable in 60 minutes
unless refreshed by a cloud license server
Action Required: The switch must reconnect to the cloud management system within 60 minutes to refresh the Subscription license. Failure to reconnect results in permanent loss of Premier feature functionality until a valid license is obtained.
Correlation Between Log Messages and Expiry Status
| Log Message Pattern | Interpretation |
|---|---|
| No "License check failed" message | Subscription valid and validated |
| "License check failed" + day countdown | Disconnected from cloud; expiration pending |
| No license log messages (after prior warnings) | License expired and features disabled |
| "License expired due to lack of connectivity" | Grace period active; 60 minutes to reconnect |
