Heh, That makes sense. So in QFX5k 'VXLAN' classifier can contain anything inside the VXLAN, like ARP? Instead of it being classified ARP, they all share VXLAN classifier? So this could also be VXLAN TTL exceeded? Which would happen every time you have some kind of convergence event, and you'll

Hi John The default DDoS values on QFX5k for EVPN-VXLAN is way too low. I recommend these values + very tight storm-control on each applicable port. RSVP and LDP are not used but share the same queue as BGP so you will see strange triggers if you omit these. set system ddos-protection protocols

The 'max arrival rate' is pre-policer, not the admitted rate. I don't use VXLAN, and I can't begin to guess what VXLAN traffic needs to punt. But this is not your transit VXLAN traffic. This is some VXLAN traffic that the platform thought it needed to process in the software. I would personally

Hi Johan I experienced a similar issue in my evpn-vxlan environment on QFX5120-48y switches. The DDOS alert occurred whenever a large number of VM migrations occurred simultaneously in my environment, some times there were 20 VM's in simultaneous migration and the DDOS alarmed. To solve this, I

Hey, Before any potential trashing, I'd like to say that as far as I am aware Juniper (MX) is the only platform on the market which isn't trivial to DoS off the network, despite any protection users may have tried to configure. > How do you identify the source problem of DDOS violations that

Hi! How do you identify the source problem of DDOS violations that junos logs for QFX? For example what interface that is causing the problem? DDOS_PROTOCOL_VIOLATION_SET: Warning: Host-bound traffic for protocol/exception VXLAN:aggregate exceeded its allowed bandwidth at fpc 0 for 30 times,
