mac flaps on catalyst

[hes]

Hello again,

I've been running two OPNsense nodes with CARP configured for a while now and had to change the HP switch they are connected to for a Cisco Catalyst.
So no changes in the OPNsense config are made.

The switch constantly reports MAC flaps, and when I log in to the VIP address I keep getting logged out (as if the MAC address indeed keeps flipping).

What would be the way to tackle this issue?

You should see something in system.log what triggered the change ...

Under System: Log Files: General it only shows the following:

3 Vlan VIPs?

Not sure what you mean by that? Can you elaborate?
