We put in a new Cisco 3850 this last weekend. The switch is working fine except for NTP. The new switch is supposed to be the NTP server for the network. However, other switches and servers are not syncing with the new switch, and I'm not seeing what the issue is. The new switch is syncing with the atomic clock fine.

ntp access-group serve-only 20
ntp server 22.214.171.124 source Vlan2
ntp server 126.96.36.199 prefer source Vlan2
ntp server 188.8.131.52 source Vlan2
ntp server 184.108.40.206 source Vlan2
Remove command ntp master. By default, if this switch is configured with the external NTP server, it will act as NTP Master for the rest of devices in your network which point to it as NTP server.
