Syntax: show sntp status
The following table describes the information displayed by the show sntp status command.
Table 6 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.
Configuring the device as an SNTP server
You can configure the Brocade 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.
To use the device as an SNTP server, enter a command such as the following at the Privileged EXEC level.
Brocade(config)# sntp server-mode use-local-clock authentication-key abc123
Brocade(config)# write memory
The above example configures the device to operate as an SNTP server with the local clock as a
reference backup and an authentication key of “abc123” and writes the configuration changes to
memory.
Syntax: [no] sntp server-mode [ use-local-clock [ stratum <stratum-number> ] ] [ authentication-key
<key-string> ]
The use-local-clock option causes the Brocade device to use the local clock as a reference source if an
upstream reference source becomes unavailable. The SNTP stratum number is set to 1 by default. You
may specify a different stratum number using the stratum option; <stratum-number> must be between
1 and 15. When the internal clock is serving as the SNTP reference source, the Brocade device will use
