ERVICE
Use the NTP Configuration page to specify the Network Time Protocol (NTP)
servers to query for the current time. NTP allows the switch to set its
internal clock based on periodic updates from an NTP time server.
Maintaining an accurate time on the switch enables the system log to
record meaningful dates and times for event entries. If the clock is not set,
the switch will only record the time from the factory default set at the last
bootup.
When the NTP client is enabled, the switch periodically sends a request for
a time update to a configured time server. You can configure up to five time
server IP addresses. The switch will attempt to poll each server in the
configured sequence.

switch attempts to update the time from the first server, if this fails it
attempts an update from the next server in the sequence. The polling
interval is fixed at 15 minutes.
