Table 6-2 General Setup
LABEL DESCRIPTION
Login Precedence Configure the local user accounts in the Access Control Logins screen. The RADIUS is an
external server. Use this drop-down list box to select which database the switch should use
(first) to authenticate a user.
Before you specify the priority, make sure you have set up the corresponding database
correctly first.
Select Local Only to have the switch just check the local user accounts configured in the
Access Control Logins screen.
Select Local then RADIUS to have the switch check the local user accounts configured in the
Access Control Logins screen. If the user name is not found, the switch then checks the
user database on the specified RADIUS server. You need to configure the Port
Authentication Radius screen first.
Select RADIUS Only to have the switch just check the user database on the specified
RADIUS server for a login username and password.
Use Time Server
When Bootup Enter the time service protocol that a timeserver sends when you turn on the switch. 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.
When you select the Daytime (RFC 867) format, the switch displays the day, month, year and
time with no time zone adjustment. When you use this format, it is recommended that you use
a Daytime timeserver within your geographical time zone.
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 1970-1-1 0:0.
Time Server IP
Address Enter the IP address 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

Current Time field after you click Apply .

New Date (yyyy-
mm-dd) Enter the new date in year, month and day format. The new date then appears in the Current

Time Zone Select the time difference between UTC (Universal Time Coordinated, formerly known as
GMT, Greenwich Mean Time) and your time zone from the drop-down list box.
