Administrator Guide

When the Dell EMC Networking OS NTP client receives inconsistent timestamp in the origin timestamp filed, it
logs the syslog message. It is due to the older versions of NTPD server implementation. Upgrade the system to
the latest NTPD package in the NTP server and the system logs the following NTP syslog message:
Dell EMC# May 30 13:27:46 %STKUNIT2-:CP %ntp-6-: receive: Unexpected origin
timestamp 0xdeb95bee.06ba346e does not match aorg 0000000000.00000000 from
server@10.16.151.117 xmt 0xdeb95bee.30907a87
In general, the packet denied services are dropped with no further action except incrementing the statistics
counters. In certain cases, a more proactive response is required to cause the client to slow down the process. A
special packet is created to serve this purpose, and it is called the kiss-o-Death (KoD) packet. When the Dell EMC
Networking OS client receives KoD packets, it logs the following syslog message:
Dell EMC# May 27 14:32:13 %STKUNIT1-:CP %ntp-6-: receive: KoD packet from
300::2 has inconsistent xmt/org/rec timestamps. Ignoring.
