Hello, On my MX240, I occasionally get log messages of this type:
May 4 20:47:38 jmx240-fmt2 jddosd[3549]: DDOS_PROTOCOL_VIOLATION_SET: Warning: Host-bound traffic for protocol/exception DHCPv4:bad-packets exceeded its allowed bandwidth at fpc 1 for 417 times, started at 2020-05-04 20:47:37 PDT May 4 20:52:55 jmx240-fmt2 jddosd[3549]: DDOS_PROTOCOL_VIOLATION_CLEAR: INFO: Host-bound traffic for protocol/exception DHCPv4:bad-packets has returned to normal. Its allowed bandwith was exceeded at fpc 1 for 417 times, from 2020-05-04 20:47:37 PDT to 2020-05-04 20:47:50 PDT I have looked at my config, and I am positively not providing dhcp service of any kind, have no dhcp relay service on the router configured, and simply fail to see how or why these messages are being triggered. I do have some virtual hosts that are acting as dhcp servers for relayed dhcp traffic, but at the point my router sees this traffic its only udp port 67 traffic being forwarded to these servers from my far away dhcp clients. I almost want to say that, despite config, the router is in fact keying into relayed dhcp traffic for some reason. Wondering how I would go about more properly diagnosing this problem? Thank you. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
