FDDI Management
6-6 Viewing FDDI Information
• Local means that the MAC is not inserted into a primary or secondary path of a dual
ring, but may be connected to one or more other nodes. This is not a valid value for the
HSIM-F6.
• Isolated means that the MAC has no connection to the ring or other concentrator ports.
• Not Available means that there is no MAC on the FDDI ring associated with the
selected SMT entity. Again, this state will not occur for the HSIM-F6.
• Unknown means that device firmware cannot determine the MAC path.
• ? indicates that NetSight Element Manager cannot determine the MAC path for the
selected ring.
Ring Configuration
The current configuration of the MAC and physical layers of the A and B ports.
Connection Policy
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 Master—>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 “Reject
X-Y” format, where X represents a port on the HSIM-F6, and Y represents the attaching
node. A checkmark in the check box next to a Connection Policy indicates that the
connection has been disallowed.
