claim token frame when it detects that the ring does not contain an
active monitor, or that the active monitor is not functioning properly.
ring_rem_station contains the number of times the token-ring
adapter removed itself from the ring after receiving a remove ring
station frame. A remove ring station frame is issued from the network
manager and forces an adapter to remove itself from the ring.
ring_sig_loss contains the number of times the token-ring adapter
detected a loss of signal on the ring.
ring_soft_err contains the number of report error frames transmit-
ted by the token-ring adapter. A report error frame is transmitted in
response to a soft error. A soft error is one that temporarily degrades
system performance but may be recovered using standard adapter
protocols.
ring_tx_beacon contains the number of times the token-ring
adapter transmitted beacon frames to the ring. A beacon frame
indicates a hard error. This count specifies the number of hard errors
detected by the adapter; the difference between this count and
ring_hard_err specifies the number of hard errors detected by other ring
stations.
rx_frm_cmpi (rint) contains the number of times the token-ring
adapter received a frame and then generated an adapter-to-attached-
system interrupt. Such an interrupt is enabled or disabled by the frame
interrupt bit (bit 4 of
RECEIVE_CSTAT). Because frames can be received
faster than the adapter can cause the interrupts, each increment of this
counter can report the reception of one or multiple frames.
rx_suspended contains the number of times the token-ring adapter
processed a receive parameter list containing both an odd address in the
forward pointer field (indicating the end of the list) and an end frame bit
equal to 0 (indicating more to follow).
total_adapt_error contains the aggregate count of token-ring
adapter hardware or software errors, the sum of the counts of
adpt_bad_dio_par, adpt_dma_rd_abort, adpt_dma_wr_abort, adpt_
parity_err, and adpt_ring_underrun variables.
