display ap counters 323
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 display sessions output. However, the
counter can differ from the counter in display 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 display 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 3Com 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.)
CCMP Pkt Replays Number of CCMP packets that were resent to the MAP by a
client.
(See the description for TKIP Pkt Replays.)
RadioResets Number of times the radio has been reset. Generally, a reset
occurs as a result of RF noise. It is normal for this counter to
increment a few times per day.
Transmit Retries Number of times the radio retransmitted a unicast packet
because it was not acknowledged. The MAP uses this
counter to adjust the transmit data rate for a client, in order
to minimize retries.
The ratio of transmit retries to transmitted packets (TxUniPkt)
indicates the overall transmit quality. A ratio of about 1 retry
to 10 transmitted packets indicates good transmit quality. A
ratio of 3 or more to 10 indicates poor transmit quality.
This counter includes unacknowledged probes. Some clients
do not respond to probes, which can make this counter
artificially high.
