FDDI Management
5-10 Viewing FDDI Information
Stations Panel
The Stations Panel displays a list of the stations on the ring to which the selected
SMT is connected, in ring sequence from the MAC, along with each station’s node
class and current topology. If the number of nodes exceeds the panel size, scroll
bars will appear in the list box that will allow you to scroll through the station list
to view the node of interest
Information provided in the Stations Panel includes:
#
An index number assigned to each station that indicates its position on the ring in
relation to the monitored SMT’s MAC address. The monitored SMT’s MAC is
always the first entry (1) in the station list.
MAC Address
Displays the 48-bit hardware address —þused for universal address assignment
—þof the node inserted into the ring. These addresses are hardcoded into the
device, and are not configurable. The address will appear in Canonical or MAC
format, as currently selected.
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 node’s MAC configuration topology.
Upstream Neighbor
Displays the hardware address (in Canonical or MAC format, as currently
selected) of each node’s upstream neighbor.
NOTE
The information displayed in the Station List is static once the window is opened;
