Parameter
Description
Remote
The domain name or IP address of the remote end of the NTP association.
"Hardware Clock" is the SyncServer's Hardware Clock. In the case of a remote
NTP connection, this will be the IP address of the remote end.
The character in the left margin indicates the mode in which this peer entry is
operating:
* (asterisk) indicates the association with which the NTP daemon is
synchronizing (the system peer on NTP - Sysinfo), marked "synchronizing".
+ (plus) indicates the SyncServer is symmetric active mode.
- (minus) indicates the SyncServer is symmetric passive mode.
= (equal) means the SyncServer is in client mode, marked "being polled".
^ (caret) indicates that the SyncServer is broadcasting to the remote node,
marked "broadcasting to".
~ (tilde) denotes that the remote node is broadcasting to the SyncServer.
Local: The IP address of the SyncServer network port at the local end of the
NTP association.
Mode
Ref Id
This is a four-byte field used to identify the reference clock source. At
initialization, while the stratum is 16, this field shows the progression of the NTP
clock PLL. The field will start with a value of INIT (may be displayed as
73.78.73.84, the ASCII decimal values).
Once a peer has been selected, the clock may be stepped, in which case the
reference ID field will change to STEP (or 83.84.69.80). Once the PLL is locked,
the stratum will be updated and the reference ID will identify the selected peer. In
the case of a SyncServer operating at stratum 1, the reference ID will display the
source for the local timing reference (e.g., GPS1, IRIG, FREE). In the case where
the selected peer is another NTP server, the reference ID will display the IP
address of the server or a hash unique to the association between the
SyncServer and the remote server.
