[XS1930-12HP] CARP MAC gets falsely marked as static

Fabian_S

I have set up two Virtual IPs using CARP on two separate OPNsense Firewalls:

WAN was assigned the MAC 00:00:5e:00:01:01 and LAN was assigned the MAC 00:00:5e:00:01:02

Firewall 1 is connected to Port 10 on the Switch and Firewall 2 is connected to Port 9.

For whatever reason, only the WAN VIP works properly and has it's MAC registered as Dynamic on the Switch. The LAN MAC wrongfully gets marked as "Type" Static.

Because of this, the OPNsense High Availability is broken. When the CARP MAC switches form one Firewall to the other, the Port on which the Switch forwards the traffic won't change and is stuck on Static. It will only work again if I restart the Switch.

Firmware V4.80(ABQF.4)

Hi @Fabian_S

We have experienced a similar issue on VMware vMotion and this issue is fixed by changing arp-learning mode. Could you help to change the arp-learning mode to ARP-request? Path: Menu > NETWORKING > ARP Setup > ARP Learning.

If the issue still exist after changing, please let me know.
