Syntax: sntp server <ip-addr> | <hostname> [<version>]
The <version> parameter specifies the SNTP version the server is running and can be from 1 – 4. The default
is 1. You can configure up to three SNTP servers by entering three separate sntp server commands.
By default, the switch or router polls its SNTP server every 30 minutes (1800 seconds). To configure the switch or
router to poll for clock updates from a SNTP server every 15 minutes, enter the following:
BigIron(config)# sntp poll-interval 900
Syntax: [no] sntp poll-interval <1-65535>
To display information about SNTP associations, enter the following command:
BigIron# show sntp associations
address ref clock st when poll delay disp
~207.95.6.102 0.0.0.0 16 202 4 0.0 5.45
~207.95.6.101 0.0.0.0 16 202 0 0.0 0.0
* synced, ~ configured
Syntax: show sntp associations
The following table describes the information displayed by the show sntp associations command.
To display information about SNTP status, enter the following command:
BigIron# show sntp status
Clock is unsynchronized, stratum = 0, no reference clock
precision is 2**0
reference time is 0 .0
clock offset is 0.0 msec, root delay is 0.0 msec
root dispersion is 0.0 msec, peer dispersion is 0.0 msec
Syntax: show sntp status
The following table describes the information displayed by the show sntp status command.

(leading character) One or both of the following:
* Synchronized to this peer
~ Peer is statically configured
address IP address of the peer
ref clock IP address of the peer’s reference clock
st NTP stratum level of the peer
when Amount of time since the last NTP packet was received from the peer
poll Poll interval in seconds
delay Round trip delay in milliseconds
disp Dispersion in seconds
Table 10.2: Output from the show sntp status command
This Field... Indicates...
unsynchronized System is not synchronized to an NTP peer.
