addresses. The switch will attempt to poll each server in the configured
sequence.
Broadcast – The switch sets its clock from a time server in the same subnet
that broadcasts time updates. If there is more than one SNTP server, the
switch accepts the first broadcast it detects and ignores broadcasts from
other servers.
Configuring SNTP
You can configure the switch to send time synchronization requests to
specific time servers (i.e., client mode), update its clock based on
broadcasts from time servers, or use both methods. When both methods
are enabled, the switch will update its clock using information broadcast
from time servers, but will query the specified server(s) if a broadcast is
not received within the polling interval.
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 Broadcast Client – Configures the switch to operate as an
SNTP broadcast client. This mode requires no other configuration
settings; the switch will obtain time updates from time server
broadcasts (using the multicast address 224.0.1.1).
•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 seconds)
•SNTP Server – In unicast mode, 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.
