Model 9289 Spectracom Corporation
NetClock/NTP Network Time Provider Instruction Manual 3-24
NOTE: Check only ONE server as the preferred reference.
NOTE: You cannot use both a Trusted Symmetrical Key ID and Autokey. Autokey essentially
automates the symmetrical key function and the two cannot be used together. If
trusted keys have been defined (Figure 3-29), they will appear in the “Trusted Sym
Key ID” dropdown menu.
NOTE: Checking the “Clear” box in the NTP References grids will immediately remove a
defined server from the list.
The dropdown menus for “Min Poll” and “Max Poll” in the NTP References grids allow the user
to choose, from within the available ranges, how often the NetClock will poll the defined servers
for timing information. Check with your network administrator for guidelines regarding network
traffic and recommended polling intervals, if any.
