MP Access Point Commands
12 – 333
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.
Note:
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 MP could not create a descriptor. A
descriptor describes a received packet’s size and its location in MP
memory. The MP buffers descriptors, and clears them during
interframe spaces.
This counter increments if the MP runs out of buffers for received
packets. This condition can occur when a noise burst temporarily
floods the air and the MP attempts to buffer the noise as packets.
Buffer overruns are normal while an MP is booting. However, if they
occur over an extended period of time when the MP is fully active, this
can indicate RF interference.
Illegal Rates Number of times a client attempted to connect with a disabled data
rate.
PktTxCount Number of packets transmitted by the radio.
MultiPktDrop Number of multicast packets dropped by the radio due to a buffer
overflow on the MP. 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 MP. (See the description for MultiPktDrop.)
User Sessions Number of clients currently associated with the radio.
Generally, this counter is equal to the number of sessions listed for the
radio in show sessions output. However, the counter can differ from
the counter in show sessions output if a client is associated with the
radio but has not yet completed 802.1X authentication. In this case,
the client is counted by this counter but not in the show sessions
output.
Although there is no specific normal range for this counter, a high or
low number relative to other radios can mean the radio is
underutilized or overutilized relative to the other radios. (However, if
the clients are VoIP phones, a relatively high number of clients does
not necessarily mean overutilization since voice clients consume less
bandwidth on average than data clients.)
MIC Error Ct Number of times the radio received a TKIP-encrypted frame with an
invalid MIC.
Normally, the value of this counter should always be 0. If the value is
not 0, check the system log for MIC error messages and contact
Trapeze Networks TAC.
TKIP Decrypt Err Number of times a decryption error occurred with a packet encrypted
with TKIP.
(See the description for CCMP Pkt Decrypt Err.)
