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
addresses
of
all
existing
clock
servers
and
the
time
to
the
new
switch.
If
a
switch
with
FOS
5.3.0
or
later
has
entered
the
fabric
it
will
be
able
to
store
the
list
and
the
active
servers;
pre-5.3.0
Fabric
OS
switches
will
ignore
the
new
list
parameter
in
the
payload
and
will
update
only
the
active
server
address.
For
more
information
on
using
an
NTP
server,
and
IPv6
considerations,
see
the
Fabric
OS
Administrator’s
Guide
.
1.
If
you
are
not
already
logged
into
the
switch;
do
so
now
using
the
default
password,
which
is
password
.
2.
Enter
the
tsClockServer
command:
switch:admin>
tsclockserver
"<ntp1;ntp2>"
where
ntp1
is
the
IP
address
or
DNS
name
of
the
first
NTP
server,
which
the
switch
must
be
able
to
access.
The
second
ntp2
is
the
second
NTP
server
and
is
optional.
The
operand
“<ntp1;ntp2>”
is
optional;
by
default,
this
value
is
LOCL,
which
uses
the
local
clock
of
the
principal
or
primary
switch
as
the
clock
server.
The
tsClockServer
command
accepts
multiple
server
addresses
in
either
IPv4,
IPv6,
or
DNS
name
formats.
When
multiple
NTP
server
addresses
are
passed,
tsClockServer
sets
the
first
obtainable
address
as
the
active
NTP
server.
The
others
will
be
stored
as
backup
servers
that
can
take
over
if
the
active
NTP
server
fails.
The
principal
or
primary
FCS
switch
synchronizes
its
time
with
the
NTP
server
every
64
seconds.

tsclockserver

The
following
example
shows
how
to
set
up
more
than
one
NTP
server
using
a
DNS
name:
switch:admin>
tsclockserver
"10.32.170.1;10.32.170.2;ntp.localdomain.net"

Changes
to
the
clock
server
value
on
the
principal
or

FCS
switch
are
