If choosing SNTP for the clock source, then the following parameters will be available: SNTP First Server: Select IPv4 or IPv6 and specify the IP address of the primary SNTP server from which the system time is retrieved. 49 5 Configuration D-Link Web Smart Switch User Manual SNTP Second Server: Select IPv4 or IPv6 and specify the IP address of the secondary SNTP server from which the system time is retrieved. SNTP Poll Interval in Seconds (30-99999): Defines the interval (in seconds) at which the SNTP server is polled for Unicast information. When selecting Local for the clock source, users can select from one of two options: Manually Time Settings: Users input the system time manually. The possible field values are: Enabled – Enables the Port Description TLV on the port. System Name: Specifies whether the System Name TLV is enabled on the port.
