In “External Server Address” you enter the IP address of the
SNTP server from which the Switch periodically obtains the sy-
stem time.
V
In “Redundant Server Address” you enter the IP address of the
SNTP server from which the Switch periodically obtains the sy-
stem time, if the Switch does not receive an answer from the “ex-
ternal server address” 0.5 seconds after making a request.
Note: If you are receiving the system time from an external/redun-
dant server address, you do not accept any SNTP broadcasts (see
below). Otherwise you can never distinguish whether the Switch is
displaying the time from the server entered, or that of an SNTP
broadcast package.
V
In “Server request interval” you specify the interval at which the
Switch requests SNTP pakkages (valid entries: 1 second to 3600
seconds, default: 30 seconds).
V
With “Accept SNTP Broadcasts” the Switch takes the system time
from SNTP broadcast/multicast packages which it receives.
