2.Select the NTP Associations tab.

3. Refer to the following SNTP Association data for each SNTP association displayed:

Address	Displays the numeric IP address of the SNTP resource (Server) providing SNTP updates to the
	switch.
Reference Clock	Displays the address of the time source the switch is synchronized to.
Stratum	Displays how many hops the switch is from a SNTP time source. The switch automatically
	chooses the SNTP resource with the lowest stratum number. The SNTP supported switch is
	careful to avoid synchronizing to a server that may not be accurate. Thus, the NTP enabled
	switch never synchronizes to a machine not synchronized itself. The SNTP enabled switch
	compares the time reported by several sources, and does not synchronize to a time source
	whose time is significantly different than others, even if its stratum is lower.
When	Displays the date and time when the SNTP association was initiated. Has the association
	been trouble free over that time?
Peer Poll	Displays the maximum interval between successive messages, in seconds to the nearest
	power of two.
Reach	Displays the status of the last eight SNTP messages. If an SNTP packet is lost, the lost
	packet is tracked over the next eight SNTP messages.
Delay (sec)	Displays the round-trip delay (in seconds) for SNTP broadcasts between the SNTP server and
	the switch.
Offset (sec)	Displays the calculated offset between the switch and SNTP server. The switch adjusts its
	clock to match the server's time value. The offset gravitates toward zero over time, but never
	completely reduces its offset to zero.
Dispersion (sec)	Displays how scattered the time offsets are (in seconds) from a SNTP time server

4.Select an existing NTP association and click the Details button to display additional information useful in discerning whether the association should be maintained.
