All of the above statistics are also sampled by the token-ring MAC-layer
Statistics group with the exception of the Active Stations statistic. For
information about the individual statistics, please refer to 10.5.1.1, “Statistics

The Active Stations statistic keeps track of the total number of active stations on
the ring detected by the probe during the sampling cycle.
Promiscuous History Group:
The token-ring Promiscuous History group collects
and stores the promiscuous token-ring statistics based on user-defined

collecting and storing the following statistics:
•
Drop Events
•
Data Octets
•
Data Packets
•
Broadcast Packets
•
Multicast Packets
•
Good non-MAC frames with lengths between:
− 18-63 octets
− 64-127 octets
− 128-255 octets
− 256-511 octets
− 512-1023 octets
− 1024-2047 octets
− 2048-4095 octets
− 4096-8191 octets
− 8192-18000 octets
− Greater than 18000 octets
10.5.1.3 Ring Station Group
The token-ring Ring Station group maintains status information and statistics
associated with each active station in the local ring. In addition, this group
provides status information for each ring being monitored.
Two tables are maintained by this group:
•
RingStationControlTable
•
RingStationTable
The
RingStationControlTable
provides the following status information about the
local ring:
