Setting up a Catalyst 3650 as a NTP server

Level 1

Hi folks,

I have two Cisco switches Catalyst 3650 stacked and I would like them to act as a NTP server but it doesn't work. the switches are synchronized from a firewall located at xx.yyy.0.1.

Below my ntp configuration:

ntp master 5
ntp server xx.yyy.0.1

Regards.

Hello @adel81,

If C3650 stacked switches are sync, ensure that clients NTP can join an IP configured on these C3650.

Please provide the output of #sh ntp association command of one client and the NTP configuration associated on that client.

Also, ensure that no ACL or FW between C3650 and the clients NTP ; if yes add flow rule associated with IPs and port udp_123.

 

Best regards
