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 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 — used for universal address assignment

—of 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.
