# Create NTP Server elements

NTP Server elements represent the external NTP servers to provide time synchronization for the SMC Appliance and Security Engines.

##

You can use the same NTP servers for the SMC Appliance and Security Engines.

For more details about the product and how to configure features, click Help or press F1.

## Steps

1. Select Network Elements.
2. Right-click Servers, then select New > NTP Server.
3. In the Name field, enter a unique name.
4. (Optional) In the Host Name field, enter the host name of the NTP server.
   Note: If you do not enter a host name, you must enter an IPv4 address or an IPv6 address.
5. (Optional) In the IP Address or IPv6 Address field, specify the IP address in one of the following ways:
   - Enter the IPv4 or IPv6 address of the NTP server.

     The same NTP Server element can have both an IPv4 address and an IPv6 address.

   - To automatically resolve the IP address from the host name in the Name field, click Resolve.
   Note: If you do not enter an IPv4 address or an IPv6 address, you must enter a host name.
6. From the Key Type drop-down list, select the key type.
7. In the Key ID field, enter a unique numerical identifier for the key.
   The value must be between 1—65534.
8. In the Key field, enter the key.
9. Click OK.
