HA-Port causing massive damaged packets

There's a strange thing happening.
I've 2 UTM 320 in HA mode and the HA interface is connected to a special vlan, on my corperate switches. Now the switch holding the preferred master utm says that the HA interface is sending massive defective packets. In the daily report I can usualy find very heavy outbound load on the eth3 HA interface.
Is that rather something related to a hardware defect or is there some configuration I'm missing. Well HA is working, so someone could say just don't care but that's not nice so...

Hi,

I believe HA uses Jumbo Frames; does your switch understand that?

FWIW, you can just use a crossover cable instead of a switch (if the NICs are gigE a normal cable works).

If your switch doesn't support Jumbo Frames, you can change the MTU of the HA ports per this knowledgebase article: How to change the MTU for HA sync interface on Astaro Security Gateway

1500 is a standard MTU that should work regardless of your switches configuration or capability.
