Hi Team,

I have a hardware with below ethernet controllers; wondering if this sufficient to carry network traffic of around 200 Mb/s? This is purely will be used for BGP peering with 2 peers and carry the link of 100 Mb/s each

Thank You - I was worrying about NIC DROPs but since its I211 should not be an issue I feel about NIC processing.

Any idea how to set rx and tx ring buffersize to 4096 from vyos shell?

What version are you using?

In 1.2:

sudo ethtool -G tx 4096 rx 4096 eth0

To change it permanently:

echo "sudo ethtool -G tx 4096 rx 4096 eth0" >> /config/scripts/vyos-postconfig-bootup.script

In 1.3+

configure
set interfaces ethernet eth0 ring-buffer rx '4096'
set interfaces ethernet eth0 ring-buffer tx '4096'
