Configuring the device as an SNTP server
2
To display information about SNTP status, enter the show sntp status command.
Syntax: show sntp status
The following table describes the information displayed by the show sntp status command.
Configuring the device as an SNTP server
You can configure the Brocade ICX 6650 device to function as an SNTP server to its downstream
clients. When using the device as an SNTP server, you can also set it to use its own internal clock
as the reference source if an upstream server becomes unavailable.
precision
The precision of the system clock in Hz.
version
The NTP version of the peer. The version can be from 1 - 4.
org time
The original timestamp of the system clock. The original timestamp is
what the client has sent to the server.
rcv time
The receive timestamp of the system clock.
xmt time
The transmit timestamp of the system clock.
TABLE 7
Output from the show sntp status command
Field
Description
unsynchronized
System is not synchronized to an NTP peer.
synchronized
System is synchronized to an NTP peer.
stratum
NTP stratum level of the upstream time server.
reference clock
IP address of the peer reference clock, or the reference ID of the
external clock source if the peer is stratum 1.
Examples of external clock source IDs: GPS, CDMA, WWV (Ft.Collins US
Radio 2.5, 5, 10, 15 MHz), CESM (calibrated Cesium clock), etc.
precision
Precision of this system's clock (in Hz)
reference time
Reference time stamp
clock offset
Offset of clock to synchronized peer
root delay
Total delay along the path to the root clock
root dispersion
Dispersion of the root path
peer dispersion
Dispersion of the synchronized peer
sntp poll-interval
Shows how often the Brocade device polls for clock updates from an
SNTP server.
