Description
NO_SYSTEM_BUFFER
32 2
B0 8
System buffer unavailable.
3
The total number of times no
system buffer was available for an
incoming frame. In conjunction
with total frames received, provides
a measure of system buffer related
receive problems. The problem
reflected in this counter is also
captured as an event. This can be
any buffer between the hardware
and the user buffers (those supplied
on Receive requests). Further
information as to potential different
buffer pools is implementation
specific.
NO_USER_BUFFER
34 2
B8 8
User buffer unavailable.
3
The total number of times no
user buffer was available for an
incoming frame that passed all
filtering. These are the buffers
supplied by users on Receive
requests. In conjunction with
total frames received, provides
a measure of user buffer related
receive problems. The problem
reflected in this counter is also
captured as an event.
FAIL_COLLIS_DETECT
-
-
C0 8
Collision detect check failure.
The approximate number of times
that collision detect was not
sensed after a transmission. If this
counter contains a number roughly
equal to the number of frames sent,
either the collision detect circuitry
is not working correctly or the test
signal is not implemented.
3
Always zero.
