Nortel Networks 2300 Series manual Output for show ap counters

	AP Commands 361
	Table 8: Output for show ap counters (continued)
Field	Description
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 Nortel 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 AP 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 AP 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.
	Note: This counter includes unacknowledged probes. Some
	clients do not respond to probes, which can make this counter
	artificially high.
Noise Floor	Received signal strength at which the AP 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.
