To page a switch: 1. Select a switch in the fabric tree. 2. Select Switch > Toggle Beacon. To cancel the beacon, reselect Toggle Beacon. Setting the date/time and enabling NTP client The Date/Time dialog box (Figure 51) enables 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, which requires an Ethernet connection to an NTP server, ensures the consistency of date and time stamps in alarms and log entries. Although the date/time is set or displayed in the firmware in Universal Time, when displayed in the Date/Time dialog box, the value is always in local time. If you select the NTP Client Enabled option (the default is deselected): • Date and Time areas become active, and you are prevented from manually setting the date and time on the switch. • NTP Server Discovery and NTP Server IP Address fields become active, and you can select a discovery method.
