LABEL	DESCRIPTION
Syslog	Select this check box to activate syslog (UNIX system logging) and then configure the
	UNIX syslog parameters described in the following fields.
Syslog IP Address	Enter the IP address of the syslog server.
Log Facility	Select one of seven different options from the drop-down list box. The log facility allows
	you to log the message to different files in the server. Please refer to your UNIX manual
	for more details.
Service Access	Service Access Control allows you to decide what services you may use to access the
Control	ES-3024. You may also change the default service port and configure “trusted
	computer(s)” for each service in the Remote Management screen (see later in this
	guide).
Services	Services you may use to access the ES-3024 are listed here.
Enable	Select the Enable check boxes for the corresponding services that you want to allow to
	access the ES-3024.
Server Port	For Telnet, FTP or web services, you may change the default service port by typing the
	new port number in the Server Port field. If you change the default port number then
	you will have to let people (who wish to use the service) know the new port number for
	that service.
Time and Date	Time and Date Setting allows you to set the time manually or get the current time and
Setting	date from an external server when you turn on your switch. The real time is then
	displayed in the switch logs.
Use Time Server	Enter the time service protocol that your timeserver sends when you turn on the switch.
When Bootup	Not all timeservers support all protocols, so you may have to use trial and error to find a
	protocol that works. The main differences between them are the time format.
	Daytime (RFC 867) format is day/month/year/time zone of the server.
	Time (RFC-868)format displays a 4-byte integer giving the total number of seconds
	since 1970/1/1 at 0:0:0.
	NTP (RFC-1305)is similar to Time (RFC-868).
	None is the default value. Enter the time manually. Each time you turn on the switch, the
	time and date will be reset to 2000-1-1 0:0.
Time Server IP	Enter the IP address (or URL if you configure a domain name server in the IP Setup
Address	screen) of your timeserver. The switch searches for the timeserver for up to 60 seconds.
	If you select a timeserver that is unreachable, then this screen will appear locked for 60
	seconds. Please wait.
Current Time	This field displays the time you open this menu (or refresh the menu).
New Time	Enter the new time in hour, minute and second format. The new time then appears in the
(hh:min:ss)	Current Time field after you click Apply.
Current Date	This field displays the date you open this menu.
New Date (yyyy-	Enter the new date in year, month and day format. The new date then appears in the
mm-dd)	Current Date field after you click Apply.
