Field

Description

 

 

 

 

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.

 

 

 

 

To display information about SNTP status, enter the show sntp status command.

Brocade# show sntp status

Clock is synchronized, stratum = 4, reference clock = 10.70.20.23 precision is 2**-20

reference time is 3489354594.3780510747

clock offset is 0.0000 msec, root delay is 0.41 msec

root dispersion is 0.11 msec, peer dispersion is 0.00 msec sntp poll-interval is 10 secs

Syntax: show sntp status

The following table describes the information displayed by 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.

 

 

 

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.
