mac flaps on catalyst
«

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?
*Jan 9 10:13:53.458: %SW_MATM-4-MACFLAP_NOTIF: Host 0000.5e00.010e in vlan 883 is flapping between port Gi0/5 and port Gi0/4
*Jan 9 10:13:53.458: %SW_MATM-4-MACFLAP_NOTIF: Host 0000.5e00.010d in vlan 883 is flapping between port Gi0/5 and port Gi0/4

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

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