ONFIGURING THE
Setting the System Clock
Simple Network Time Protocol (SNTP) allows the switch to set its internal
clock based on periodic updates from a time server (SNTP or NTP).
Maintaining an accurate time on the switch enables the system log to
record meaningful dates and times for event entries. You can also manually
set the clock using the CLI. (See "calendar set" on page 4-74.) If the clock
is not set, the switch will only record the time from the factory default set
at the last bootup.
When the SNTP client is enabled, the switch periodically sends a request
for a time update to a configured time server. You can configure up to
three time server IP addresses. The switch will attempt to poll each server
in the configured sequence.
Configuring SNTP
You can configure the switch to send time synchronization requests to
specific time servers.
Command Attributes
•
SNTP Client – Configures the switch to operate as an SNTP unicast
client. This mode requires at least one time server to be specified in the
SNTP Server field.
•
SNTP Poll Interval – Sets the interval between sending requests for
a time update from a time server when set to SNTP Client mode.
(Range: 16-16284 seconds; Default: 16)
•
SNTP Server – Sets the IP address for up to three time servers. The
switch attempts to update the time from the first server, if this fails it
attempts an update from the next server in the sequence.
