Radio represents the RF Module; 1 or 2 (cnReach N500).

Tx Bytes represents the amount of data transmitted by the RF Module.

Tx Frames represents the amount of Ethernet Frames transmitted by the RF Module.

Rx Bytes represents the amount of data received by the RF Module.

Rx Headers represents the number of RF Headers received by the RF Module. Headers are part of the

cnReach N500 OTA protocol and are not part of the Ethernet Frame. Headers are used to encapsulate

Ethernet frames over the air. Since Ethernet Frames can be broken up into fragments depending on the

RF packet size, there can be more headers than actual Ethernet Frames.

Rx Frames indicates how many Ethernet Frames have been received by the RF Module.

Rx Header CRC Errors indicates the amount of CRC errors detected during receive.

Rx Frags Out of Order represents fragmented Ethernet Frames that arrived out of order.

Rx Frag Length Errors represents the fragmented Ethernet Frame being received with a different

length and is usually the result of fragments being lost over the air.

Rx Frame CRC Errors indicates how many CRC errors have been detected receiving the Layer 2

Ethernet Frame.

Rx Frame Age Errors indicates errors with age of the Ethernet Frame being received, usually a result of

excessive time taken for a missing fragment to arrive, where the radio will give up and drop the pieces

of the Frame that have been received.

Rx Frames Out of Order indicates Layer 2 Ethernet Frames being received out of order.

Rx Frame Length Errors indicates the Ethernet Frame has been received with a different length and is

usually caused by fragments being lost over the air. Since a frame can have multiple fragments this

identifies how many Frames have encountered a problem.

Rx Frames Own Src MAC directly relates to the “Bounce” setting and is the number of Frames

transmitted by an End Point that have been bounced by the Access Point. The End Point needs to

detect and drop these Frames to prevent Ethernet protocol issues.

Rx Frames Control is a count of control messages sent between the RF Module and the Ethernet board.
