Table 7 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.
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 network until the last
message is received from the system clock. To update the system clock with the last message received,
you can enable the SNTP client to either listen to all NTP broadcast servers on any interface, or enable
the SNTP client to listen to only one specific NTP broadcast server.
To enable an SNTP client in a broadcast mode to listen to all NTP servers on any interface, enter the sntp
broadcast client command.
Brocade(config)#sntp broadcast client
Syntax: sntp broadcast client
The sntp broadcast client command enables an SNTP client to listen to all NTP servers, and update the
client’s clock with the last message received from any NTP server.
To enable an SNTP client to listen to only one specific IPv4 NTP broadcast server, enter the following
commands.
