ITCNTR - Interface terminal counter
The terminal counter is the actual number of terminals defined on this
Mux interface card.
IFRTRY - Reset retry count
This is used to count the number of times the Mux interface has been
reset due to a backplane timeout, or firmware failure. It is incremented
by ZMON each time the Mux card is reset by a request from the DAM. If
it reaches an unsatisfactory level, the Mux card will be disabled (set
down) by ZMON.
The driver will decrement the retry count if it is not zero after every 30
successful status $STDT replies (i.e., every 5 minutes). If an unstable
Mux interface fails and restarts too often, the ZCOM subsystem will
mark it as “down” and stop using it.
IRSERR - Restart error count
This field contains the count of the number of errors which occurred
during the last restart or enable. These errors are due to $PORT or
$TERM commands and will be separately reported to ZMON. This field
is kept for information purposes only.
IFSTCN - Status update request count
This counts the number of $STDT replies until IFRTRY will be
decremented.
INTFNO - Interface card number
This is the interface number that was specified in the Mux statement of
the TTGEN configuration file.
IMAXPORTS - Maximum number of ports on card.
