This places the controllers into a Not in Service mode for SNTP on the switches.<BR /> Does this eventually time out, and they become active? Is there a way to reset this? Why would the controller's do this if they are set to be NTP servers?<BR /> Thanks,<BR /> Bill<BR /> Wed, 06 Jun 2018 22:20:00 GMT https://community.extremenetworks.com/t5/extremeswitching-eos/quot-received-kiss-of-death-packet-quot/m-p/17154#M448 Bill_Handler 2018-06-06T22:20:00Z https://community.extremenetworks.com/t5/extremeswitching-eos/quot-received-kiss-of-death-packet-quot/m-p/17155#M449 I would contact the GTAC for further review. <A href="https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-contact-Extreme-Networks-Global-Technical-Assistance-Center-GTAC" target="_blank" rel="nofollow noreferrer noopener">https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-contact-Extreme-Networks-Global-Tec...</A><BR /> <BR /> Tue, 19 Jun 2018 16:39:00 GMT https://community.extremenetworks.com/t5/extremeswitching-eos/quot-received-kiss-of-death-packet-quot/m-p/17155#M449 Doug 2018-06-19T16:39:00Z
