Token Ring Interface Card Statistics
Token Ring-Like Statistics Group
Appendix A122
denotes a condition where a transmitting station in
strip mode does not receive the trailer of the frame
before the TRR timer goes off.
Receive Congestions
This counter is incremented when a station recognizes
a frame addressed to its specific address, but has no
available buffer space indicating that the station is
congested.
Frame Copied Errors This counter is incremented when a station
recognizes a frameaddressed to its specific address and
detects that the FS field A bits are set to 1 indicating a
possible line hit or duplicate address.
Token Errors This counter is incremented when a station acting as
the active monitor recognizes an error condition that
needs a token transmitted.
Soft Errors The number of Soft Errors that interface has detected.
It directly corresponds to the number Report Error
MAC frames that this interface has transmitted. Soft
errors are those which are recoverable by the MAC
layer protocols.
Hard Errors The number of times this interface has detected an
immediately recoverable fatal error. It denotes the
number of times this interface is either transmitting or
receiving beacon MAC frames.
Signal Loss The number of times this interface has detected the
loss of a signal condition from the ring.
Transmit Beacons The number of times this interface has transmitted a
beacon frame.
Ring Recovery The number of Claim Token MAC frames received or
transmitted after the interface has received a Ring
Purge MAC frame. This counter signifies the number of
times the ring has been purged and is being recovered
back into a normal operating state.
Lobe Wire Faults The number of times the interface has detected an
open or short circuit in the lobe data path. The card
will be closed and the Ring State will signify this
condition. Be sure to check the Token Ring cable
connections.
