FDDI Management
6-10 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.
Note that the information displayed in the Station List is static once the window is opened;
for updated information, click on the Refresh button.
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 hardware address (in Canonical or MAC format, as currently selected) of each
node’s upstream neighbor.
