CCMP Pkt Transfer
Ct
Total number of CCMP packets sent and received by the
radio.
Radio Recv Phy Err Ct Number of times radar caused packet errors. If this counter
increments rapidly, there is a problem in the RF environment.
This counter increments only when radar is detected.
Rate-specific Phy errors are instead counted in the PhyError
columns for individual data rates.
Radio Adjusted Tx
Pwr
Current power level set on the radio. If RF Auto-Tuning of
power is enabled, this value is the power set by RF
Auto-Tuning. If RF Auto-Tuning is disabled, this value is the
statically configured power level.
802.3 Packet Tx Ct Number of raw 802.3 packets transmitted by the radio.
These are LocalTalk (AppleTalk) frames. This counter
increments only if LocalTalk traffic is present.
No Receive
Descriptor
Number of packets for which the MAP could not create a
descriptor. A descriptor describes a received packet’s size
and its location in MAP memory. The MAP buffers
descriptors, and clears them during interframe spaces.
This counter increments if the MAP runs out of buffers for
received packets. This condition can occur when a noise
burst temporarily floods the air and the MAP attempts to
buffer the noise as packets.
Buffer overruns are normal while a MAP is booting.
However, if they occur over an extended period of time
when the MAP is fully active, this can indicate RF
interference.
PktTxCount Number of packets transmitted by the radio.
MultiPktDrop Number of multicast packets dropped by the radio due to a
buffer overflow on the MAP. This counter increments if there
is too much multicast traffic or there is a problem with the
multicast packets. Normally, this counter should be 0.
MultiBytDrop Number of multicast bytes dropped by the radio due to a
buffer overflow on the MAP. (See the description for
MultiPktDrop.)
