The requested concentrator attachment type. For a
dual attachment concentrator which can be
connected to the trunk ring, the first FDDI port
is configured as A and the second FDDI port is
configured as B.
For a single attachment concentrator which can be
connected beneath another concentrator, the first
FDDI port is configured as M and the second FDDI
port is configured as S. For a null attachment
concentrator which can be located at the root of
the tree, the first two FDDI ports are configured
as M.
This object does not take effect until the
concentrator is reset. The current attachment
type can be determined from snmpFddiPORTPCType
for ports 1 and 2.
