Hi Guys,
I'm using Cisco VSS Core Switch C6807-XL with Software Version 15.4 and i have few other edge switches, ASA firewalls, routers & windows servers as NTP server on the LAN, i have configured the Core Switch to take time from Windows NTP server and other network devices "edge switches, ASA firewalls, routers" take time from Core Switch.
Network devices are working fine, synchronized and taking time from the Core Switch but Core Switch is not taking time from windows NTP server and it is synchronized with IP address 127.127.1.1
Could you please advice where is the mistake that Core Switch not taking the IP from Windows NTP server
