We have a few Palo Alto firewalls in several locations where we are seeing a weird behavior.
The firewalls are connected directly to switches and in some ports of the switch we see two learned MAC addresses: one 001b17-XXXXXX belonging to the FW´s interface but also another one 34e5ec-XXXXXX for which we cannot find explanation. Both MACs belongs to Palo Alto devices: https://maclookup.app/macaddress/34E5EC
We cannot find MAC 34e5ec-XXXXXX referenced in any part of the configuration or log within tech support file.
Did anyone address the same situation before?
