mapShowDatabase
The
SDG
Router
maintains
a
database
of
attached
devices
to
ensure
that
each
time
a
host
attaches
to
the
SDG
Router,
the
target
devices
are
seen
at
a
consistent
address.
The
database
lists
not
only
the
devices
presently
connected,
but
also
devices
that
were
previously
connected.
If
a
previously
attached
device
is
later
reattached,
it
is
assigned
its
previous
address.
Use
the
mapShowDatabase
command
to
display
the
persistent
device
map
table.
