C H A P T E R 3 Accessing the Switch
The command syntax to configure GMT offset and usage of
Daylight Savings is as follows:
config timezone <GMT_offset> {autodst |
noautodst}
The GMT_OFFSET is in +/- minutes from the GMT time.
Automatic Daylight Savings Time (DST) changes can be
enabled or disabled. The default setting is enabled.
3 Enable the SNTP client using the following command:
enable sntp-client
Once enabled, the switch sends out a periodic query to the
NTP servers defined later (if configured) or listens to
broadcast NTP updates from the network. The network time
information is automatically saved into the on-board real-
time clock.
4 If you would like this switch to use a directed query to the
NTP server, configure the switch to use the NTP server(s). If
the switch listens to NTP broadcasts, skip this step. To config-
ure the switch to use a directed query, use the following com-
mand:
config sntp-client [primary | secondary] server
[<ip_address> | <hostname>]
NTP queries are first sent to the primary server. If the
primary server does not respond within one second, or if it is
not synchronized, the switch queries the secondary server (if
configured). If the switch cannot obtain the time, it restarts
the query process. Otherwise, the switch waits for the
sntp-
client update interval
before querying again.
5 Optionally, the interval for which the SNTP client updates the
real-time clock of the switch can be changed using the follow-
ing command:
config sntp-client update-interval <seconds>
The default
sntp-client update-interval
value is 64
seconds.
