# Interface Statistics

The statistics page reports the amount of traffic received and sent by each of the three interfaces: Ethernet, Serial, and RF. This page also reports statistics gathered from the airlink that can indicate the quality of the RF links.
Note: All definitions given below use the following convention:
RX (or Input) = data received from a lower network layer
TX (or Output) = data transmitted to a lower network layer

Cycling power to the Viper or pressing the "Clear (Zero) Interface Stats" button will reset all statistics to zero.

## Ethernet

### RX Pkts (LAN)

The total number of input packets received by the Ethernet interface.

### TX Pkts (LAN)

The total number of output packets transmitted by the Ethernet interface.

## Serial

### RX Bytes

The total number of input bytes received by the port.

### TX Bytes

The total number of output bytes transmitted by the port.

### RX Pkts

The total number of input packets received by the port.

### TX Pkts

The total number of output packets transmitted by the port.

## RF

### RX Pkts (OIP Sublayer)

The total number of input packets received by RF-OIP interface.

### TX Pkts (OIP Sublayer)

The total number of output packets transmitted by RF-OIP interface.

### Rx Ctrl Pkts (Airlink Sublayer)

The total number of control packets received over-the-air. These packets may be RTS/CTS messages or RF Acknowledgements.

### Rx Data Pkts (Airlink Sublayer)

The total number of input data packets received over-the-air.

### Tx Ctrl Pkts (Airlink Sublayer)

The total number of output control packets transmitted over-the-air. These packets may be RTS/CTS messages or RF Acknowledgements.

### Tx Data Pkts (Airlink Sublayer)

The total number of output data packets transmitted over-the-air.

## Airlink error detection

Airlink parameters provide the user with information about the quality of the RF link.

### Reliable service msg success count

The number of service messages that succeeded. RF Acknowledgements must be enabled in order to generate a Reliable Service Message.

### Reliable service msg failure count

The number of service messages that failed.

### Total retry count

The number of retries for service messages.

### Noise detected count

The number of noise (non Viper carrier) detected above the carrier sense level. If the Noise detected count is high, it may be an indication that the Carrier Sense Threshold should be raised.

### RX total "other" count

This is the total number of messages the Viper overheard that were intended for another station. These messages are discarded.
