I have a great problem with our time synchronization. In our network there are two switches Cisco 3750E (as coreswitch). One of them (first) has a default ntp (server external) but the other switch cannot sync the time from the first switch. The time from the second switch is after 15 minutes.
How can I sync this second switch with the first one? Which command can I use to sync a switch with another source?
config#ntp server 192.168... ..
It does not work. The server is registered but not sync...
#show ntp associations
adress ref clock st when poll reach
+~18.104.22.168 .PTB. 1 477 1024 377
* ~22.214.171.124 .PTB. 1 160 1024 377
Thanks for your help!
