the next leap second will be inserted on December 31, 2016, at 23:59:60 UTC. https://en.wikipedia.org/wiki/Leap_second Are Extreme Networks products vulnerable to Leap Second? Is it going to effect to all extreme xos ???
Paul, The vulnerability does not depend on time zone if NTP module is present it can be affected. EXOS version older than EXOS 16.2.1, and 21.1.1 are affected. Here is an article for reference https://gtacknowledge.extremenetworks.com/articles/Vulnerability_Notice/VN-2015-002-Leap-Second If NTP module is present then disable ntp before 24 hours of the leap second insertion and Wait a day after the leap second and then re-enable NTP
Paul, That is correct, may be you have typo on the year. disable ntp at 23:59:00 PM, 30 Dec, 2016 UTC enable ntp at 23:59:00 PM, 1 Jan, 2017 UTC The leap second insertion would happen on December 31, 2016, at 23:59:60 UTC. would be fine.
As long as the switch X450a-24x do not get the leap second insertion packet it will remain unaffected.
