[SOLVED] Netin grouped data statistics

[ddkargas]

For some days now I've noticed that it appears that netout / outgoing traffic from one vm is presented to all other vm's as netin incoming traffic on statistics
in every host in pve-manager.

Someone else has noticed something similar?

In fisrt image vm with netout traffic on other images is some vm's on same host in same time

Hi,
sound like broadcast or unicast flooding on your network

Good morning spirit, thanks for the reply.
Do you have any idea how I can find this in my network?

 

[spirit]

I think the only is to use tcpdump and look at the traffic.

for unicast flood, do a tcpdump on tap<vmid>X interfaces on proxmox host, and check if you see traffic with destination ip which shouldn't be to this vm.

I this is ok now, is wrong configuration in network vmbr bridge interface's
after change in host bridge config from

bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off

to

bridge_stp off
bridge_fd 0

working ok now

yes, you should change bridge_maxage to a value lower than arp cache of your vms guests.
