Logical Module Representation
FDDI Modules
SMT Address
Displays the 48-bit individual address of the MAC used for SMT frames.
RMT State
Indicates the current state of the RMT State Machine. The possible values
are; isolated, non_op, ring_op, detect, non_op_dup, ring_op_dup, directed, and
trace.
Duplicate Address Flag
Displays the RMT flag Duplicate Address.
UNA Duplicate Address Flag
Displays a flag which is set when the upstream neighbor reports a duplicate
address condition. It is cleared when the condition clears.
Frame Condition
When set, this field indicates that the MAC Frame Error Condition is present.
It is cleared when the condition clears and on station initialization.
Hardware Present
Indicates the presence of underlying hardware support for this MAC object.
FDDI MAC Parameters View
To access this view, do the following:
1. Highlight the MAC icon on the FDDI NMM logical module
2. Select MAC Parameters from the Icon Subviews menu.
The view displays the following information:
SMT Index
Displays the value of the SMT index associated with this MAC.
MAC Index
Displays the index variable for uniquely identifying the MAC object instance.
SMT Address
Displays the 48-bit individual address of the MAC used for SMT frames.
T_Max Capability
Indicates the maximum time value that this MAC can support.
TVX Capability
Indicates the maximum time value that this MAC can support.
T_Req
This variable is the T_Req_value passed to the MAC. It is reported as a twos-
complement number as described in the MAC standard. Without having
detected a duplicate, the time value of this variable shall assume the
maximum supported time value which is less than or equal to the time value.
When a MAC has an address detected as a duplicate, it may use a time value
