Dear Community,
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?
Thank you!

Hello,
Is the connection from the PAN to the switch trunked? These could be vlan interfaces or other interfaces from the internal PAN being broadcast to the switch.
