Notes:
•
A packet is the basic unit of transmission. A packet may or may not contain a payload.
A payload is user data, which may be an Ethernet frame or a logical link layer control
message.
•
WEP is not supported in this release.
•
The CCU maintains a transmit queue for each EUM. The length of this queue is
limited, to prevent one EUM from consuming all the resources and impacting service
to other EUMs. Discards indicate excessive load by one EUM, possibly due to large
TCP windows.
•
Registration occurs once per EUM and/or CCU boot time. Deregistration may occur if
an EUM is not authorized (a registration/deregistration request pair occurs periodically
while that EUM is powered ON) or if the EUM does not respond to multiple
consecutive polls, such as when it is powered OFF.
•
Association occurs when there is traffic to send to or from an EUM. Disassociation
occurs if there is no traffic to or from an EUM for a short period of time.
APCD-LM043-4.0
Value
OID
Type
44
Counter
Number of payloads returned to the host because too
many other EUMs were already associated .
45
Counter
Number of payloads returned to the host because of
timeout.
46
Counter
Number of payloads returned to the host because the
transmit queue for the EUM was too long (see note 4).
47
Counter
Not used.
48
Counter
Number of times that no response was received to a
directed poll.
49
Counter
Number of times that the MAC layer recovered from
an internal error or unexpected event.
50
Counter
Number of registration requests received (see note 5).
51
Counter
Number of registration responses transmitted (see
note 5).
52
Counter
Number of deregistration requests transmitted (see
note 5).
53
Counter
Number of times no response was received from an
EUM, after multiple polls (see note 5). This statistic
indicates a poor radio link to one or more EUMs.
54
Counter
Number of disassociation requests transmitted (see
note 6).
55
Counter
Number of times the CCU has determined than an
EUM should be disassociated (see note 6).
