Configuring DCBX
Consider
an
example
consistent
and
used
with
the
previous
FCoE
examples
in
this
chapter:
FCoE
is
used
on
port
INTA1.
CEE
features
are
also
used
with
LANs
on
ports
INTA2
and
EXT1.
All
other
ports
are
disabled
or
are
connected
to
non
‐
CEE
devices.
In
this
example,
the
CN4093
acts
as
the
central
point
for
CEE
configuration.
FCoE
‐
related
ports
will
be
configured
for
advertising
CEE
capabilities,
but
not
to
accept
external
configuration.
Other
LAN
ports
that
use
CEE
features
will
also
be
configured
to
advertise
feature
settings
to
remote
peers,
but
not
to
accept
external
configuration.
DCBX
will
be
disabled
on
all
non
‐
CEE
ports.
This
example
can
be
configured
using
the
following
commands:
1.
Turn
CEE
on.
Note:
Turning
CEE
on
will
automatically
change
some
802.1p
QoS
and
802.3x
standard
flow
control
settings
and
menus
(see
2.
