3.8.4 Radio Packet Statistics
The previous screen dealt with Ethernet-related information. The Radio
Packet Statistics menu (Figure 3-33) contains statistics that relate
directly to over-the-air transmission of data. It provides valuable insight
into the quality of the RF link between entraNET units with respect to
the handling of data packets.

• Overflow—TX packets with “lcp buffer overflow” data
responses.
• No Ack—Number of packets that were sent but not acknowl-
edged.
• Lost Data—TX packets lost; over-the-air retries exceeded.
• Timeout—TX data packets lost; contention timeout.
• Good Data—Data packets with Cyclic Redundancy Check
(CRC) “good” responses.
• Failed—TX packets failed; data integrity failed.
• Over the Air Data—Data packets successfully delivered
over-the-air.
• Frags—Total fragments of data received.
• Retries—Total number of times packets were re-transmit-
ted.
• Diags—TX packets with “Remote not Synchronized” data
responses.
3.8.5 Event Log Menu
The transceiver’s microprocessor monitors many operational parame-
ters and logs them. Events are classified into four levels of importance,
which are described in Table 3-1. Some of these events will result from
a condition that prevents the normal of the unit—these are “critical”
