## Symptoms

- * Unable to connect to a cluster member installed on an HP Open Server through SSH after an upgrade from R81.20 to R82.

* Running the `ethtool -p ethX` command on the cluster member causes a different interface than expected to light up.

* Running the `show interface ethX state` command on the cluster memebr shows the link state as down.

## Cause

During the upgrade process, the HP Open Server firmware resets the interface configuration in the `00-05-XX.rules` file to its default settings. This causes the interface IDs in the file to revert to their initial configuration (pre-Check Point setup), leading to mismatched interface mappings.
