4. Enter the Sync Retry Attempts: (the default & maximum = 3). This is the # of
times that any time server would be tried if time synchronization fails.
5. Select “Ignore Deviation Error” option for the maximum deviation (absolute
difference between clock time and NTP time) to be ignored and the clock time
set to the NTP Time Server during time synchronization. If not checked
(default), and the previous condition occurs, the clock will not be set to that
Time Server.
And
Select “Send e-mail and/or SNMP trap notification if it completely fails to
set the time” If checked, and time synchronization fails, a message would not
be sent until all enabled time servers have been tried. If not checked, a
message will be sent every time a time synchronization failure occurs, which is
the default.

1. Click on the Time Servers link under Time Sync, and the Time Server List
screen will appear (see Figure 4-12). The Auto-Sync Time Clock provides 18
default Stratum 1 NTP servers for the user. Additionally, the user can add up to
14 additional time servers for a total of 32 time servers. The user can not delete
any of the 18 predefined time servers, but any user created time server can be
deleted. The time server order signifies the order that they will be tried for time
synchronization, i.e., number 1, then number 2, etc.
2. To change the time server priority order, highlight the desired time server in the
list, and click the
or buttons to change the time server
order. The time server order controls the order that the enabled time servers
will be used to validate the time at the clock. The first time server with a
successful time sync is the one used. The next time server in the list will only be
used upon failure to time sync within the 1-3 programmed sync attempts with
the previous time server.
