Versioning Overview
When you enable high-availability versioning, you can have two different but compatible images on the
active and standby supervisor engines. The active supervisor engine exchanges image version
information with the standby supervisor engine and determines whether the images are compatible for
enabling high availability. If the active and standby supervisor engines are not running compatible image
versions, you cannot enable high availability.
Image versioning is supported in supervisor engine software release 5.4(1)CSX and later releases. With
versioning enabled, high availability is fully supported with the active and standby supervisor engines
running different images as long as the images are compatible. The only fully compatible images are as
follows:
•
•
Images that are compatible with all modules except Gigabit Ethernet switching modules are as follows:
•
•
•
Images that are compatible with Gigabit Ethernet switching modules but not compatible with
10/100BASE-T modules are as follows:
•
Attempting to run incompatible image versions could result in configuration loss.
