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.
