2. Select the NTP Associations tab.
3. Refer to the following SNTP Association data for each SNTP association displayed:
Address
Reference Clock
Stratum
When
Peer Poll
Reach
Delay (sec)
Offset (sec)
Dispersion (sec)
290
Displays the numeric IP address of the SNTP resource (Server) providing SNTP
updates to the switch.
Displays the address of the time source the switch is synchronized to.
Displays how many hops the switch is from a SNTP time source. The switch
automatically chooses the SNTP resource with the lowest stratum. 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.
Displays the date and time when the SNTP association was initiated. Has the
association been trouble free over that time?
Displays the maximum interval between successive messages, in seconds to the
nearest power of two.
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.
Displays the round-trip delay (in seconds) for SNTP broadcasts between the SNTP
server and the switch.
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.
Displays how scattered the time offsets are (in seconds) from a SNTP time server
