LAGG options - LACP vs Failover

[spetrillo]

Hello all,

I am not well versed with LAGG options but I am looking at LACP vs Failover mode. Can you let me know which is better for providing resiliency, as well as performance?

Thanks,
Steve

Hi,
   you should select LACP, just make sure that LACP always needs to be done in pairs, as in 2, 4, 6 NIC's. Once one interface fails you'd continue to function with degraded performance.

Thanks for that. I have a 4 port device I am using. One port is for WAN, one is for LAN(Mgmt network), and the final two ports are going into a LAGG for streaming, IoT, and wireless.

With the LACP lagg will both ports be utilized for inbound/outbound operations?

short answer is yes. you have to realize that all the tagging or whatever you choose to do will have to be performed on the LACP interface not individual interfaces, as they are a bundle moving forward.
