Helmonder Posted March 4, 2022 Share Posted March 4, 2022 I have a bond0 configured that consists out of 3 network interfaces in an active-backup setup: eth0 and eth1 are the regular nic's on my motherboard (1G) eth2 is a Mellanox SFP+ 10G connection to my switch Since this is an active-backup setup only one should be active, how is priority of the NIC's decided within a bond ? Does the system do this on its own ? Is active-backup the best bonding type I can choose ? Since my NIC's are unbalanced (one beiing 10G and two 1G) I think that mode-0 would not be beneficial since the 1G's would be used in some cases... Would mode 5 balance-tlb be something I could use ? Also: Can unavailability of a NIC be notified in some way ? Otherwise all nic's within the bond could gradually and unnoticed die off untill the last one dies and the connection is gone..

NIC's are chosen by their sequence definition in the bonded interface, which is normally eth0, eth1, eth2, etc ... 15 minutes ago, Helmonder said: Is active-backup the best bonding type I can choose ? Yes, the general advice is use active-backup mode when interfaces differ in speed (focus is on availability), and use a balanced mode when all interfaces are equal (focus is on performance) 18 minutes ago, Helmonder said: Also: Can unavailability of a NIC be notified in some way ? On the Dashboard you can see which interfaces are up or down Quote Link to comment

My 10G is now eth2 so I should switch that with the eth0 1G then... Correct ? 1 Quote Link to comment
