https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11503#M2531 Hi Carsten,<BR /> only the reset to factory default and new configure resolves the problem. Now sntp works fine.<BR /> thanks for help<BR /> Volker<BR /> Tue, 24 Jun 2014 13:40:00 GMT Volker 2014-06-24T13:40:00Z https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11499#M2527 Hi,<BR /> one Enterasys B5 Switch (one of 15) can't get the correct Time from sntp server. <BR /> Message like "No active server- poll abortetd" are logged. All Definitions like Timezone, summertime, sntp server def's, etc. are correct. The Firmware states an equal. Restarting didnt fix the probelm.<BR /> All other B5 are working fine with sntp. What can i do to fix this ?<BR /> regards<BR /> Volker<BR /> Mon, 16 Jun 2014 14:21:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11499#M2527 Volker 2014-06-16T14:21:00Z https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11500#M2528 Hi Volker, <BR /> is it possible to ping the SNTP-Server by the B5 ? - is the host-VLAN and the default gateway the right one ?<BR /> <BR /> Is the B5 only working in L2-Mode - or did you have configured routing on it ?<BR /> Otherwise it could be possibel to use the "set sntp interface....." command.<BR /> <BR /> Regards,<BR /> Carsten<BR /> <BR /> Mon, 23 Jun 2014 16:51:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11500#M2528 C_Heitmann 2014-06-23T16:51:00Z https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11501#M2529 Hi Carsten,<BR /> <BR /> yes i can ping the sntp-server by the B5. The host vlan is correct and the default vlan as well. The B5 is L2 Switch, there is no routing defined.<BR /> <BR /> These B5 is exactly defined like a second b5 in the same vlan and like all other B5. by show sntp i get "<B>Last SNTP Update: THU JAN 01 00:00:00 1970"</B> every time. i deleted all the time statements in config and include all the parameters again. but nothing changes. the shown time is + 2hr. <BR /> regards<BR /> Volker<BR /> <BR /> Tue, 24 Jun 2014 09:40:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11501#M2529 Volker 2014-06-24T09:40:00Z https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11502#M2530 Hi Volker,<BR /> can you take a trace on the sntp-Server ? It would be interesting if the B5 sntp request arrived the server or not. If the request arrived the server, you could trace on the B5-site if the server response arrived at the B5.<BR /> Take a reboot to restart all services on the B5 and check it again.<BR /> Otherwise -if the configuration and SW ist the same like all other B5, i would reset the B5 to factory default, reboot und configure new. <BR /> <BR /> regards,<BR /> Carsten<BR /> <BR /> Tue, 24 Jun 2014 12:44:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11502#M2530 C_Heitmann 2014-06-24T12:44:00Z https://community.extremenetworks.com/t5/extremeswitching-other/b5-sntp-problem/m-p/11503#M2531 Hi Carsten,<BR /> only the reset to factory default and new configure resolves the problem.
