Configuring SNTP
1
Configuring an SNTP server location
You can define the SNTP server’s location and specify an IP address or hostname. You can
configure up to three SNTP servers by entering three separate sntp server commands.
To configure an SNTP server location, enter a command such as the following.
ServerIronADX(config)# sntp server 1.1.1.1
Syntax: [no] 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.
Defining how often the clock references are validated
To define how often the clock references are validated between the devices, enter a command
such as the following.
ServerIronADX(config)# sntp poll-interval 3
Syntax: [no] sntp poll-interval <value>
The default <value> is 1800 seconds.
Synchronizing the system clock
To manually synchronize the ServerIronADX’s system clock with the time supplied by the SNTP
server, enter the following command.
ServerIronADX# sntp sync
Syntax: sntp sync
Displaying SNTP information
To verify communications, enter the following command.
Syntax: show sntp
The following table describes the information displayed by the show sntp status command.
