Synchronizing local time using Network Time Protocol (NTP)

You can synchronize the local time of the principal or primary Fabric Configuration Server (FCS) switch to
a maximum of eight external network time protocol (NTP) servers. To keep the time in your SAN current, it
is recommended that the principal or primary FCS switch has its time synchronized with at least one
external NTP server. The other switches in the fabric will automatically take their time from the principal or
primary-FCS switch, as described in
All switches in the fabric maintain the current clock server value in non-volatile memory. By default this
value is the local clock server <LOCL> of the principal or primary FCS switch. Changes to the clock server
value on the principal or primary FCS switch are propagated to all switches in the fabric.
When a new switch enters the fabric, the time server daemon of the principal or primary FCS switch sends
out the clock server address(es) and time to the new switch. If a switch running version 5.3.0 or later has
entered the fabric it will be able to store the list and the active server; pre-5.3.0 Fabric OS switches will
ignore the new list parameter in the payload and will update only the active server address.
If the active NTP server configured is IPv6, then distributing the same in the fabric will not be possible to a
pre-5.3.0 switch since IPv6 is not supported; the default value LOCL will be distributed to pre-5.3.0
switches.
