The timestamp of the syslog messages differs from the time synchronized from the NTP server

Latest reply: Apr 26, 2017 01:55:55 1604 1 0 0 0

The S5700 switch synchronizes its time from a NTP server which provides the time in an UTC format. The switch is located in a different region with the NTP server and is configured to add an offset of 2 hours to the UTC time according to the local time zone. Along with the NTP configuration the switch is set to send the log information to a syslog server where the logs are received with a different timestamp than the current time of the device.

Warning: There is security risk as this operation enables a non secure syslog protocol.       



The timestamp of the logs received on the syslog server present the time in UTC format:

The timestamp of the syslog displays the UTC time by default and in this situation we should adjust the syslog configuration by adding the local-time parameter in the info-center loghost command as below:

[R6_U24_S5710_Stack]info-center loghost local-time  


After the local-time parameter is added, the syslog messages should be sent with the current time of the switch.
