12.1.3 Configuring time servers and time synchronization with NTP

Using NTP functionality, synchronize the system clock of the Switch with a time server.

Figure 12-1: NTP Configuration Diagram (Time Synchronization to Time Servers)

Points to note

When multiple time servers are configured in the network, the prefer parameter of the ntp server command selects the time server for synchronizing the system clock of the Switch. If you omit the prefer parameter, the selected time server will be the one with the least stratum value, or a randomly selected time server if they all have the same stratum value.

Command examples

1. (config)# ntp server 192.168.1.100

   Synchronizes the Switch with the time server whose IP address is 192.168.1.100.
