Configuring the device as an SNTP server
2
Displaying SNTP server information
Use the show sntp server-mode command to display the status of the SNTP server and its
configuration.
Syntax: show sntp server-mode
Enabling broadcast mode for an SNTP client
The Brocade device can be configured as an SNTP client. You can enable an SNTP client to function
in a broadcast mode when the NTP server is within the same LAN, and the expected delay in
response to calibrate the system clock is minimal. In a broadcast mode, the SNTP client will not
send queries to the NTP server. The SNTP client will listen to any number of NTP servers on the
TABLE 8 Output from the show sntp server-mode command
Field Description
status The operational state of the SNTP server. “Up” means that the SNTP port is
open; “down” means that the SNTP port is closed. (If sntp server-mode is
disabled, the show sntp server-mode command will display the message
“SNTP server is not operational.)
stratum Stratum number of this server. The range is from 1 through 15. If the device is
synchronized to an upstream SNTP server, this will show that server’s stratum
number +1. If the device is unsynchronized and using the use-local-clock
option, this will show the user-specified stratum number (or the default value
of “1” if no stratum has been configured).
authentication Authentication key used. If authentication has been configured successfully,
this displays “md5.” If not, it displays “none.”
clock source The source of the reference time. When the reference source is an upstream
SNTP server, this will show the IP address of the upstream server. When the
internal clock of the device is being used as the reference, this will show
“local-clock.”
last upstream sync The last upstream time-server synchronization, displayed in timestamp format.
This field is not displayed if the time source is the local clock.
last responses sent to clients The last responses sent to downstream clients (maximum of five unique
clients), displayed in reverse chronological order. Each entry shows the IP
address of the client and the timestamp sent.
