RingView for Token Ring
RingView for Token Ring
Known Anomalies:
Problem 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 through which the hubs are connected. Since SPECTRUM’s fault
isolation capability is based on the connections between models, this firmware
limitation may result 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 would flash gray to
indicate that their condition was unknown. However, if connections within the ring
were not fully mapped, then the Token Ring devices would have no known neighbors
as far as SPECTRUM is concerned, and would thus flash red.
Solution: When Ring In/Ring Out ports are being used to connect hubs within a Token Ring
LAN, you must resolve port connections manually to ensure accurate alarms and
fault isolation.
