Table 12– 2 describes the fields in this display.
Table 12– 2. Output for show ap counters
Field Description
AP Distributed MP number.
radio Radio number.
LastPktXferRate Data transmit rate, in Mbps, of the last packet received by the MP.
NumCntInPwrSave Number of clients currently in power save mode.
LastPktRxSigStrength Signal strength, in dBm, of the last packet received by the MP.
LastPktSigNoiseRatio Signal-to-noise ratio (SNR), in decibels (dB), of the last packet
received by the MP access point.
This value indicates the strength of the radio signal above the noise
floor. For example, if the noise floor is -88 and the signal strength is
-68, the SNR is 20.
If the value is below 10, this indicates a weak signal and might
indicate a problem in the RF environment.
TKIP Pkt Transfer Ct Total number of TKIP packets sent and received by the radio.
TKIP Pkt Replays Number of TKIP packets resent to the MP by a client.
A low value (under about one hundred) does not necessarily indicate a
problem. However, if this counter is increasing steadily or has a very
high value (in the hundreds or more), a Denial of Service (DoS) attack
might be occurring. Contact Trapeze Networks TAC.
CCMP Pkt Decrypt Err Number of times a decryption error occurred with a packet encrypted
with CCMP.
Occasional decryption errors do not indicate a problem.
However, steadily increasing errors or a high number of errors can
indicate that data loss is occurring in the network. Generally, this is
caused by a key mismatch between a client and the MP. To locate the
client that is experiencing decryption errors (and therefore is likely
causing this counter to increment on the MP), use the show sessions
network session-id session-id command for each client on the radio.
After you identify the client that is causing the errors, disable and
reenable the client (wireless NIC).
CCMP Pkt Transfer Ct Total number of CCMP packets sent and received by the radio.
