Specifying A Simple Network Time Protocol (Sntp) Server - Dell PowerConnect B-RX Configuration Manual

Specifying a Simple Network Time Protocol (SNTP) server

You can configure the device to consult SNTP servers for the current system time and date.
NOTE
The device does not retain time and date information across power cycles. Unless you want to
reconfigure the system time counter each time the system is reset, Brocade recommends that you
use the SNTP feature.
To identify an SNTP server with IP address 208.99.8.95 to act as the clock reference for a device,
enter the following.
BigIron RX(config)# sntp server 208.99.8.95
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 device polls its SNTP server every 30 minutes (1800 seconds). To configure the
device to poll for clock updates from a SNTP server every 15 minutes, enter the following.
BigIron RX(config)# sntp poll-interval 900
Syntax: [no] sntp poll-interval <1-65535>
To display information about SNTP associations, enter the following command.
BigIron RX# show sntp associations
address
~207.95.6.102
~207.95.6.101
* synced, ~ configured
Syntax: show sntp associations
The following table describes the information displayed by the show sntp associations command.
