Specifying an SNTP server
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.
root delay The total delay time in milliseconds along the path to the root clock.
root disp The dispersion of the root path in milliseconds.
delay The round trip delay to the peer in milliseconds.
offset The offset of the peer clock relative to the system clock.
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 11 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.
