TReq (Requested Target Token Rotation Time)
Displays the token rotation time bid made by the noted MAC during ring
initialization, in milliseconds. T-Req is stored within the MIB in nanoseconds
rather than milliseconds; SPMA converts nanoseconds to milliseconds according
to the following formula:
(snmpFddiMACTReq) divided by 10
You can use any SNMP Set Request tool to edit the T-Req value; just remember
that you must enter your value in nanoseconds, not milliseconds.
TNeg
Displays the winning token rotation time submitted by an FDDI ring station
during the ring initialization, in milliseconds. The station with the lowest token
rotation time bid wins the right to initialize the ring.
Current Path
Indicates which FDDI ring the noted MAC is attached to:

Charts, Graphs, and Meters

You can view both an FDDI MAC Chart and FDDI MAC Meters (and, if you are
running SPMA in conjunction with HP Network Node Manager or IBM NetView,
an FDDI MAC Graph) for each available MAC entity by clicking on the
appropriate buttons at the bottom of the SMT/MAC Configuration window.
Graphing capabilities are provided by an application that is included in HP Network Node
Manager and IBM NetView; therefore, graphs are only available when SPMA is run in
NOTES
conjunction with one of these network management platforms. If you are running SPMA
in a stand-alone mode or in conjunction with SunNet Manager, no graphing capabilities
are available and no graph-related options will be displayed on buttons or menus. Note
that the screens displayed in this guide will include the graph-related options where they
are available; please disregard these references if they do not apply.
Only general information about charts, graphs, and meters is provided in the following
sections; for more detailed information, see the SPMA Tools Guide.
SMT/MAC Configuration
Primary –– the MAC is physically on the primary path.
Secondary –– the MAC is physically on the secondary path.
Local –– the MAC is physically on an internal local path and is not associated
with the dual ring.
Isolated –– the MAC is not associated with any physical path.
? –– SPMA cannot determine the current MAC path.
