324 CHAPTER 11: MANAGED ACCESS POINT COMMANDS
Noise Floor Received signal strength at which the MAP can no longer
distinguish 802.11 packets from ambient RF noise. A value
around -90 or higher is good for an 802.11b/g radio. A value
around -80 or higher is good for an 802.11a radio. Values
near 0 can indicate RF interference.
802.3 Packet Rx Ct Number of raw 802.3 packets received by the radio. These
are LocalTalk (AppleTalk) frames. This counter increments
only if LocalTalk traffic is present.
The counters above are global for all data rates. The counters below are for
individual data rates.
If counters for lower data rates are incrementing but counters for higher data rates
are not incrementing, this can indicate poor throughput. The poor throughput can
be caused by interference. If the cause is not interference or the interference cannot
be eliminated, you might need to relocate the MAP in order to use the higher data
rates and therefore improve throughput.
TxUniPkt Number of unicast packets transmitted by the radio..
TxMultiPkt Number of multicast packets transmitted by the radio.
TxUniByte Number of unicast bytes transmitted by the radio.
TxMultiByte Number of multicast bytes transmitted by the radio.
RxPkt Number of packets received by the radio.
RxByte Number of bytes received by the radio.
UndcrptPkt Number of undecryptable packets received by the radio. It is
normal for this counter to increment even in stable networks
and does not necessarily indicate an attack. For example, a
client might be sending incorrect key information. However,
if the counter increments rapidly, there might be a problem
in the network.
UndcrptByte Number of undecryptable bytes received by the radio. (See
the description for UndcrptPkt.)
PhyError Number of packets that could not be decoded by the MAP.
This condition can have any of the following causes:
Collision of an 802.11 packet.
Packet whose source is too far away, thus rendering the
packet unintelligible by the time it reaches the MAP.
Interference caused by an 802.11b/g phone or other
source.
It is normal for this counter to be about 10 percent of the
total RxByte count. It is also normal for higher data rates to
have higher Phy error counts than lower data rates.
