Advanced Feature Privilege Mismatch; Minor Mismatch For Stack Units - Arris Ruckus ICX 7850 Series Configuration Manual

The active controller generates a log message whenever it puts a stack unit into a non-operational state. The following examples
describe the types of mismatches and the related log message:
• Advanced feature mismatch - The active controller is enabled for advanced features (such as BGP), and the stack unit is
not enabled.
Stack: Unit 2 0000.0020.0100 doesn't have the matching advanced feature privileges
• Image mismatch - A stack unit is running a different software image than the active controller is running.
Stack: Unit 2 0000.0020.0100 image mismatch
• Configuration mismatch - The module configuration for a stack unit does not match the reserved configuration on the
active controller.
Stack: Unit 2 0000.0020.0100 config mismatch
• Memory allocation mismatch - The active controller does not have enough memory to accommodate the stack unit.
Stack: Malloc failure for unit 2.0000.0020.0100

Advanced feature privilege mismatch

Advanced feature privileges must be enabled to run features such as BGP. For advanced features to operate across the stack,
both the active controller and standby controller must be enabled for advanced features. A unit that is not enabled for these
features is put into a non-operational state.
If the active controller is not enabled for advanced features, these features will not operate on the stack.

Minor mismatch for stack units

With a minor mismatch, an operating stack can still exist, but traffic is dropped from all ports except the stacking ports for units
with the mismatched software. You can download the correct image to the mismatched devices from the active controller. A
minor software mismatch means that there is no IPC or election algorithm change, but there is a release version disparity. Minor
software mismatches can occur with patch release upgrades. The system logs and displays a message similar to the following.
Warning! put stack unit 2 to non-operational reason=image mismatch
The show stack command displays output similar to the following.

|-------------------------------------
Normally, the system recovers from a minor image mismatch using the Auto Image Copy feature. However, if the feature has
been disabled or if the configuration of a stack unit does not match the configuration of the active controller, the stack unit does
not function. In this example, unit 2 is non-operational due to an image mismatch. To correct this situation, use the copy flash
flash command. Refer to
