◆ NTP Server IP Address – Adds the IPv4 or IPv6 address for up to 50
time servers. The switch will poll the specified time servers for updates

(Configure General) page. It issues time synchronization requests at a
fixed interval of 1024 seconds. The switch will poll all the time servers
configured, the responses received are filtered and compared to
determine the most reliable and accurate time update for the switch.
◆ Version – Specifies the NTP version supported by the server.
(Fixed: Version 3)
◆ Authentication Key – Specifies the number of the key in the NTP
Authentication Key List to use for authentication with the configured
server. NTP authentication is optional. If enabled on the System > Time
