The RingStationTable stores status information and statistics of individual
stations detected to be physically present on the local ring. For each station, the
following information is stored in the RingStationTable :
10.5.1.4 Ring Station Order Group
The token-ring Ring Station Order group maintains a table that lists the ring
stations ordered according to the ring poll with respect to the RMON probe. The
location of each station is denoted by an index. With the RMON probe assigned
an index of one, indexes for other stations are assigned depending on how many
stations downstream they are from the RMON probe.
The station s MAC address is stored together with its index in the table. This
table can be used as a quick cross-reference for locating stations based on the
way they are ordered.
