MAC Interface Statistics
MAC Interface Statistics present operational information about data which is processed by the
CCU and EUM MAC layer. These statistics are described in Table 84.
As noted in Table 84, most of the MAC interface statistics are available in a WaveRider MIB.
Table 84 MAC Interface Statistics
Statistic Description
Rx Data Payloads Number of data payloads received correctly from the
air interface.
Rx Data Octets Number of data octets received correctly from the air
interface.
Rx Ctrl Payloads Number of control payloads received correctly from
the air interface.
Rx Payload Fail Invalid Type Number of times an unknown type of payload was
received from the air interface.
Rx Payload Fail Giant Number of times a payload that was too long was
received from the air interface, and therefore
discarded.
Null Rx Descriptors Number of times the internal MAC receive interface
was corrupted.
Tx Data Payloads Number of data payloads transmitted to the air
interface.
Tx Data Octets Number of data octets transmitted to the air interface.
Tx Ctrl Payloads Number of control payloads transmitted to the air
interface.
Tx Payload Fail Invalid Type Number of times a payload of an unknown type was
discarded.
Tx Payload Fail Giant Number of times a payload that was too long was
discarded.
Tx Payload Fail Invalid Desc Number of times the internal MAC transmit interface
was corrupted.
Atmel Tx Buffer full on arrival Number of transmit packets that were queued for
delivery.
Command Time Outs Number of times the MAC-layer management
message was incomplete.
Command Missed IRQs Number of times there was no response to the MAC-
layer management message.
