RingView for Token Ring
Known Anomalies
Item Description Solution
1 RingView cannot fully map connections
within a ring that is configured with
multiple hubs or concentrators. This is
because the Token Ring device firmware
stops mapping MAC addresses to specific
ports as soon as it encounters one of the
Ring In/Ring Out ports connecting the
hubs.
Since SPECTRUM’s fault isolation is
based on connections between models,
this firmware limitation results in
situations where alarms are not
reported, or are reported incorrectly.
Normally, if SpectroSERVER loses
contact with a router that connects to a
Token Ring LAN, the icons within the
LAN’s Topology view flash gray to
indicate their condition is unknown. If
connections within the ring are not fully
mapped, the Token Ring devices have no
known neighbors (as far as SPECTRUM is
concerned) and flash red.
When Ring In/Ring Out ports are used to
connect hubs within a Token Ring LAN,
you must resolve port connections
manually to ensure accurate alarms and
fault isolation.
