Hello.
I'm trying to set up my home network lab with three virtual machines (two linux, one Cisco viosl2 switch device)

But during my experiments I realized that my switch is not working properly, the reason I suspect is that it is not receiving frames from linux, and even more strange is that he learns the mac address of the two vmbr interfaces but it does not work!

I tried using the link https://forum.proxmox.com/threads/lldp-frames-between-vms-using-linux-bridge.95029/的方法设置vmbr4和vmbr5的group_fwd_mask值为0x4000 but it still doesn't do anything.

What I find most suspicious is that if I replace the switch with a router or asav firewall he will work fine, I'm very confused about this and I would appreciate if someone could help me!
 
As for why I'm guessing the switch is failing to receive frames is because I enabled debug arp mode in the switch and it still failed to show anything back (I kept pinging another host in the process)
