mxrouterctl: Set bonding xmit hash policy to layer 2+3

[Donald Buczek (donald)]

This is designed to be used on a routeri to router link so use xmit hash of layer 2+3 in a LAG bond to get a better load balance.

[Paul Menzel (pmenzel)]

Is there a way to test the improved balancing?

Yes. Here's a tool:

root@bka:~# mxrouterctl exec /home/buczek/monitor-ifload.pl

Before: net02_tx used to be fixed to zero:

net01_rx: 17894       
net02_rx: 11749       
gnz_rx  : 29643       
net01_tx: 13164       
net02_tx: 0           
gnz_tx  : 13164       

After:

net01_rx:    7466574
net02_rx:      19187
gnz_rx  :    7485761
net01_tx:    1217434
net02_tx:    1838649
gnz_tx  :    3056083

Note, that the accumulation interval has been increased from a few seconds to 5 minutes, so the numbers have other magnitudes. And you need to wait 5 minutes if you want to reproduce. Sometimes a link is dominated by a specific connection, e.g. backup traffic to the Proxmox backup server.

Our rx side (the GNZ sending side) is not balanced, but that is a problem on the other end and F.M. want to look into it.
