Configuring the device as an SNTP server 2

Displaying SNTP server information

Use the show sntp server-modecommand to display the status of the SNTP server and its configuration.

Syntax: show sntp server-mode

TABLE 8	Output from the show sntp server-modecommand
Field		Description
status		The operational state of the SNTP server. “Up” means that the SNTP port is
		open; “down” means that the SNTP port is closed. (If sntp server-mode is
		disabled, the show sntp server-modecommand will display the message
		“SNTP server is not operational.)
stratum		Stratum number of this server. The range is from 1 through 15. If the device is
		synchronized to an upstream SNTP server, this will show that server’s stratum
		number +1. If the device is unsynchronized and using the use-local-clock
		option, this will show the user-specified stratum number (or the default value
		of “1” if no stratum has been configured).
authentication		Authentication key used. If authentication has been configured successfully,
		this displays “md5.” If not, it displays “none.”
clock source		The source of the reference time. When the reference source is an upstream
		SNTP server, this will show the IP address of the upstream server. When the
		internal clock of the device is being used as the reference, this will show
		“local-clock.”
last upstream sync		The last upstream time-server synchronization, displayed in timestamp format.
		This field is not displayed if the time source is the local clock.
last responses sent to clients		The last responses sent to downstream clients (maximum of five unique
		clients), displayed in reverse chronological order. Each entry shows the IP
		address of the client and the timestamp sent.

Enabling broadcast mode for an SNTP client

The Brocade device can be configured as an SNTP client. You can enable an SNTP client to function in a broadcast mode when the NTP server is within the same LAN, and the expected delay in response to calibrate the system clock is minimal. In a broadcast mode, the SNTP client will not send queries to the NTP server. The SNTP client will listen to any number of NTP servers on the
