FN - 70489 - PKI Self-Signed Certificate Expiration in Cisco IOS and Cisco IOS XE Software
FN - 70489 - PKI Self-Signed Certificate Expiration in Cisco IOS and Cisco IOS XE Software
Problem Description
Self-signed X.509 PKI certificates (SSC) that were generated on devices that run affected Cisco IOS® or Cisco IOS XE software releases expire on 2020-01-01 00:00:00 UTC. New self-signed certificates cannot be created on affected devices after 2020-01-01 00:00:00 UTC. Any service that relies on these self-signed certificates to establish or terminate a secure connection might not work after the certificate expires.
This issue affects only self-signed certificates that were generated by the Cisco IOS or Cisco IOS XE device and applied to a service on the device. Certificates that were generated by a Certificate Authority (CA), which includes those certificates generated by the Cisco IOS CA feature, are not impacted by this issue.
Note: To be impacted by this issue, a device must have a self-signed certificate defined AND the self-signed certificate must be applied to one or more features as outlined below. Presence of a self-signed certificate alone will not impact the operation of the device when the certificate expires and does not require immediate action.
