NTP Routers Work, Switches dont

[daniel_growth]

My routers are able to pick up the NTP servers time and clock settings.

my switches on the other hand are unable to.

I have attached the packet tracer file.

Thanks in advance for any advice :)

Hi @daniel_growth ,

NTP is a layer3 protocol, so switches must have an  IP address and gateway in their administration vlan interface.

After set up the IP parameters to the switches, I suggest you try a ping to the NTP server.

For example:

Warmingham-Switch(config)#interface vlan 1

Warmingham-Switch(config-if)#ip address 10.0.2.4 255.255.255.224

Warmingham-Switch(config-if)#no shutdown

Warmingham-Switch(config-if)#exit

Warmingham-Switch(config)#ip default-gateway 10.0.2.1

Warmingham-Switch#ping 10.0.2.3

Success rate is 80 percent (4/5), round-trip min/avg/max = 0/0/0 ms

Warmingham-Switch#show clock
