  • 1.  QFX LAG

    Edit: Site A has two QFX 5120's in a virtual chassis and Site B has two QFX's in a virtual chassis and between site A and B is the LAG.

    I have a LAG configured between QFX 5120 switches with two member interfaces on each side. I'm currently not running LACP and have an issue with one of the interfaces flapping. This in turn caused the AE interface to flap as well. The minimum links configured is set to 1 currently and the mode is set to force-up. The issue was related to a bad SFP causing layer 2 checksum errors which made the interface flap.

    Did you sort this out yourself or is there still a question in there? Why not use LACP (with fast timers)?
