Syntax: sntp server <ip-addr> | <hostname> [<version>]
The <version> parameter specifies the SNTP version the server is running and can be from 1 – 4. The default
is 1. You can configure up to three SNTP servers by entering three separate sntp server commands.
By default, the switch or router polls its SNTP server every 30 minutes (1800 seconds). To configure the switch or
router to poll for clock updates from a SNTP server every 15 minutes, enter the following:
BigIron(config)# sntp poll-interval 900
Syntax: [no] sntp poll-interval <1-65535>
To display information about SNTP associations, enter the following command:
BigIron# show sntp associations
