Network: MAC Address (MAC_Addr)
This display provides the media access control (MAC) address for both network ports (eth0 and
eth1).
Network: REBOOT
This is a way to reboot the Sonoma and is necessary after you’ve nished conguring the network
parameters. Until you do this, the network parameters that are shown will be the active settings, NOT
the new settings. The new settings will become active after you reboot.
NTP Menu
The NTP Menu is selected from the Main Menu and provides access to the Status, I/O Statistics and
Setup displays described below:
NTP: Status
This display provides information associated with the NTP Subsystem.
Stratum: This stratum eld has three possible values:
Stratum 1: The server is fully synchronized and accurate.
Stratum 2: The server is synchronized to a Stratum 1 server.
Stratum x: The server is synchronized to a Stratum x-1 server.
Stratum 16: The server is unsynchronized. NTP clients will not use a Stratum 16
server.
Source: The synchronization source is named here. For the Sonoma CDMA the source is CDMA,
IP address of upstream source, or none.
Offset: The NTP offset indicates the accuracy of the NTP system clock relative to the CDMA
Subsystem clock. Initially, if the offset between the NTP system clock and the CDMA
Subsystem clock is large the display will indicate “not available”. After the CDMA
Subsystem locks, the NTP clock will synchronize to the CDMA Subsystem. Once
synchronization is complete, the typical offsets will range over approximately
+/- 1 microsecond.
LI Bits: Shows the status of the leap indicator bits as sent by the Sonoma time server to the
clients in the NTP reply packets. Leap seconds occur every 2-3 years.
Possible indicator values are:
00: Normal, locked operation.
01: Leap second insertion event will occur at UTC midnight.
10: Leap second deletion event will occur at UTC midnight.
11: Fault. Unsynchronized state.
NTP: I/O Statistics (I/O_Stats)
This display shows some key information regarding the operation of the NTP daemon. The informa-
tion includes the time since reset and the counts of received, sent and dropped packets, and the sent
packet rate.
