NS 3000/iX FDDI Link Statistics
Ring up time. The number of seconds the FDDI ring has been up since
the driver was started. Subtracting this number from the Num of
heartbeats value will provide the number of seconds that the ring has
been down. Note the ring being down does not by itself indicate a
problem with this node. The ring will not be up unless the FDDI
concentrator and other nodes are configured and active.
Read buffs in pool. The number of buffers in the inbound buffer pool.
Ring drops. The number of times the ring down signal has been
received during the life of the driver.
Read buffs avail. The number of buffers in the inbound buffer pool
that are currently queued within the driver.
Loquix reinits. The number of times the Loquix chip has been
reinitialized.
Read buffer size. The size in bytes of the buffers in the inbound buffer
pool.
SMT events. The number of SMT events received by the driver.
Flag Status
The status of several flags are printed here. If a flag’s status is not
reported here then that flag is NOT set. The meaning each flag is
briefly described here.
Io_tx. The IO_TX_STATUS register has been read since the last card
interrupt.
Io_cmd. The IO_CMD_STATUS register has been read since the last
card interrupt.
Lan_in_active. An inbound DMA buffer has been posted to the card.
Lan_out_active. An outbound DMA is currently active.
Ctrl_out_active. An outbound control operation is currently active.
Configured. The FDDI card has been successfully configured.
Trace_on. Tracing has been enabled for this FDDI link.
Reset_on. The FDDI card is currently being reset.
Pfail_on. The FDDI card is currently recovering from a powerfail.
Bmgr_queued_aloc_on. A buffer manager queued allocation request
is pending.
Config_on. The FDDI card is currently being configured.
Post_read_pending. The driver is temporarily out of inbound buffers
to post to the card.
