The ControlBus Statistics page lists the following information:

RX bad Multicast CRC - the number of multicast received cyclic redundancy
check (CRC) errors since the last power on, module reset, or Internet Cache
Protocol (ICP) Object Reset Service received.

Multicast CRC Error Threshold - the threshold value for entering a fault state due
to multicast CRC errors.

RX bad CRC - the number of directed receiver CRC errors since the last power
on, module reset, or ICP Object Reset Service received.

RX Bus Timeouts - the number of receiver bus timeouts since the last power on,
module reset, or ICP Reset Service received.

TX bad CRC - number of transmit CRC errors since the last power on, module
reset, or ICP Object Reset Service received.

TX Bus Timeouts - the number of transmit bus timeouts since the last power on,
module reset, or ICP Reset Service received.

TX Retry Limit - the number of times to retry a frame if any transmit error occurs.

Status - the current status of the ICP object:

0 (for bit 0) = Normal communications; RX disabled; reflects the current
status of all receivers.

1 (for bit 1) = Multicast RX disabled: reflects the current status of the
multicast receiver

2 (for bit 2) = RA/GA miscompare; a persistent indication of a RA/GA
miscompare.
