The NTP Association screen displays the following:
Delay Time
Displays the round-trip delay (in seconds) for broadcasts between the NTP
server and the access point.
Display
Displays the time difference between the peer NTP server and the access
point’s clock.
Offset
Displays the calculated offset between the access point and the NTP
server. The access point adjusts its clock to match the server’s time value.
The offset gravitates towards zero overtime, but never completely reduces
its offset to zero.
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.
Reference IP
Address
Displays the address of the time source the access point is synchronized
to.
Server IP Address
Displays the numerical IP address of the SNTP resource (server) providing
SNTP updates to the access point.
State
Displays the NTP association status. This can be one of the following:
Synced - Indicates the access point is synchronized to this NTP server.
Unsynced - Indicates the access point has chosen this master for
synchronization. However, the master itself is not yet synchronized to UTC.
Selected - Indicates this NTP master server will be considered the next
time the access point chooses a master to synchronize with.
Candidate - Indicates this NTP master server may be considered for
selection the next time the access point chooses a NTP master server.
Configured
- Indicates this NTP server is a configured server.
Status
Displays how many hops the access point is from its current NTP time
source.
