SNTP Configuration Commands
Table 14 describes SNTP configuration commands.
SNTP Example
In this example, the switch queries a specific NTP server and a backup NTP server. The switch is
located in Cupertino, CA, and an update occurs every 20 minutes. The commands to configure the
switch are as follows:
config timezone -480 autodst
config sntp-client update interval 1200
enable sntp-client
config sntp-client primary server 10.0.1.1
config sntp-client secondary server 10.0.1.2
Table 14: SNTP Configuration Commands
Command Description
config sntp-client [primary | secondary] server
[<ipaddress> | <host_name>]
Configures an NTP server for the switch to
obtain time information. Queries are first
sent to the primary server. If the primary
server does not respond within 1 second,
or if it is not synchronized, the switch
queries the second server.
config sntp-client update-interval <seconds> Configures the interval between polling for
time information from SNTP servers. The
default setting is 64 seconds.
disable sntp-client Disables SNTP client functions.
