Fabric OS 5.0.0 command reference guide 695
Displays or sets the NTP Server address.
Synopsis
tsclockserver [ipaddr]
Availability
all users (display)
admin (set)
Description
Use this command to synchronize the local time of the principal or primary FCS switch to an external NTP
server.
The time server daemon synchronizes fabric time by sending updates of the principal or primary FCS local
switch time periodically to every switch in the fabric. The time server daemon runs on all switches in the
fabric, but only the principal switch (when the security feature is not enabled) or the primary FCS switch
(when the security feature is enabled) connect to the NTP server and broadcast time service updates.
All switches in the fabric maintain the current clock server IP address in flash memory. By default, this value
is LOCL. Changes to the clock server IP address on the principal or primary FCS switch are propagated to
all switches in the fabric.
Use this command with no parameters to display the current clock server IP address being used. Specify
the ipaddr operand to set the clock server IP address and enable fabric-wide clock synchronization with
the specified clock server.
The NTP server used must support a full NTP client. Fabric OS v3.1.0 and v2.6.1 have an SNTP client and
hence will accept an SNTP or NTP server, but v4.1.0 has an NTP client, so for the proper functioning of a
mixed fabric with external time synchronization it is necessary that an NTP server that supports a full NTP
client be used.
The ipaddr specified should be the IP address of an NTP server and should be accessible from the
switch. When a clock server IP address other than LOCL is specified but is not used by the fabric, a
warning is displayed and logged. When a clock server IP address other than LOCL is specified, the date
command is restricted to display only. Refer to the date command for more details.
NOTE: When secure mode is enabled, this command can be run on all switches to view the NTP server
IP address. You can only modify the NTP server IP address on the primary FCS switch.
Operands
This command has the following operand:
If no operand is specified, the current value displays.
tsClockServer
ipaddr Specify the IP address of the NTP server. This operand is
optional. By default, this value is LOCL.
