FDDI Management
State
Displays a value that indicates the port’s connection status. There are four possible connection states:
•Connecting ––the port is trying to establish a link, but has not yet been successful. Ports which are not connected and which have not been disabled by management will display this status.
•Active ––the port has been enabled by management and has successfully established a link with its downstream neighbor.
•Standby ––the port has a physical link, but the SMT Connection Policy is prohibiting a logical connection to the ring because the attempted connection is illegal. FDDI protocol always forbids connecting two Master ports; all other connections are theoretically legal, although some are not desirable.
Refer to Configuring the SMT Connection Policy, page 4-21, for more information.
•Disabled ––the port has been disabled by management; note that this status does not indicate whether or not there is a physical link connected to the port.
Connection
A port’s connection is defined by its own port type (A or B) and the port type to which it is connected. For example, a normal connection for a FDDI A port would be A––>B(a “thru” configuration); a port that has no connection will display as B––>None.
Media Type
Indicates the type of cable segment connected to the port; possible values are:
•Multimode Fiber
•Single Mode Fiber 1
•Single Mode Fiber 2
•SONET
•Low-cost Fiber
•Twisted Pair
•Unknown (firmware can’t locate the information)
•Unspecified (information is not included in the firmware)
•? (firmware is not responding to the request)
