6-10 FDDI Performance
MAC Address
Displays the manufacturer-set MAC address of the node inserted into the ring.
MAC addresses are hard-coded into the device and are not conÞgurable.
Node Class
Displays the type of ring device. Possible values are:
Station Indicates an FDDI node capable of transmitting,
receiving, and repeating data.
Concentrator Indicates an FDDI node that provides attachment points
to the ring for stations that are not directly connected to
the dual ring.
Topology
Indicates the nodeÕs MAC conÞguration topology.
Upstream Neighbor
Displays hardware address (in Canonical or MAC format, as currently selected) of
each nodeÕs upstream neighbor.
