Setting the Date/Time and Enabling NTP Client
The Date/Time dialog allows you to manually set the date, time, and time zone on
a switch, or to enable NTP (Network Time Protocol) Client to synchronize the date
and time on the switch with an NTP server. Enabling the NTP client requires an
Ethernet connection to an NTP server, but ensures the consistency of date and
time stamps in alarms and log entries. When the date/time is set or displayed in
the firmware, it is always in Universal Time. However, when displayed in the
Date/Time dialog, the value is always in local time. If the NTP Client Enabled
option is selected (default is un-selected), the Date and Time areas becomes
inactive, thus preventing you from manually setting the date and time on the
switch. The NTP Server Discovery and NTP Server IP Address fields become
active, and allow you to select a discovery method (Static, DHCP, DHCPv6) and to
specify an IP address.
To manually set the date and time on a switch, do the following:
1. Open the Switch menu, and select Set Date/Time.
2. In the NTP area of the Date/Time dialog, clear (un-select) the NTP Client
Enabled option. The fields in the Date and Time areas become active.
3. Enter the day, year, hour, and minutes.
4. Select a month and time zone from the drop-down lists.
5. Click the OK button. The new date and time take effect immediately.
To synchronize the date and time on the switch with an NTP server, do the
following:
1. Open the Switch menu, and select Set Date/Time.
2. In the NTP area of the Date/Time dialog, select the NTP Client Enabled
option. The fields in the Date and Time areas become in-active.
3. Select a time zone from the Select Time Zone drop-down list.
4. Select an NTP Server Discovery option from the drop-down list.
5. Enter an NTP Server IP Address.
6. Click the OK button.
NOTE:
The difference between switch and workstation times must not exceed 24
hours, or the switch management application can not connect using SSL.
