vQFX is not receiving traffic

Post by NitrousOxyde » Thu Jan 09, 2020 6:03 pm

Hi mates,

Recently while playing with vQFX 15 on EVE, I've noticed one interesting thing - it appears that interfaces on vQFX are not forwarding any traffic. I've tried different scenarios - created a LAG with/without LACP, configured interface in access mode, and when checking, I can see that switch is sending certain packets(LACP, BPDU) but nothing is received. Even when I disable LACP on LAG and it comes up, it does not receive any traffic. Any ideas why this could happen?

Anyone has faced this problem? I've tried both 15.x and 18.x, same issue.
