6-6 Connection Policy Window
¥ Secondary 2 indicates that the Secondary 2 FDDI ring is being used.
¥ Local means that the MAC is connected to one or more nodes but is not
connected to the dual ring.
¥ Isolated means that the MAC has no connection to the ring or other
concentrator ports.
¥ Unknown or ? indicates that your Cabletron management application cannot
determine the MAC path for the HSIM-F6.

The current conÞguration of the MAC and physical layers of the A and B ports.
Connection Policy Window
The SMT Connection Policy of an FDDI concentrator determines which types of
connections are allowed among the four FDDI port types: A, B, M (Master), and S
(Slave). FDDI protocol forbids MasterÑ>Master connections; all other connection
types are legal, although some are considered to be undesirable.
The Connection Policy window, Figure 6-3, lists potential connection types in a
ÒReject X-YÓ format, where X represents a port on the HSIM-F6, and Y represents
the attaching node. An checkmark in the check box next to a Connection Policy
indicates that it is an illegal connection.
