Routing & Switching

The video shows how to configure time synchronization on a router and switch using NTP. Two routers will be configured as NTP master/peers, while providing time to a switch. Having an accurate time on your network devices is critical for producing meaningful logging messages needed for troubleshooting, and any network services relying on time accuracy such as certificate-based authentication.
