NN47250-100 (Version 02.51)
TKIP Pkt Replays Number of TKIP packets that were resent to the AP 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 Nortel 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 AP. To
locate the client that is experiencing decryption errors (and
therefore is likely causing this counter to increment on the AP),
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.
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 AP could not create a
descriptor. A descriptor describes a received packet’s size and its
location in AP memory. The AP buffers descriptors, and clears
them during interframe spaces.
This counter increments if the AP runs out of buffers for received
packets. This condition can occur when a noise burst temporarily
floods the air and the AP attempts to buffer the noise as packets.
Buffer overruns are normal while an AP is booting. However, if
they occur over an extended period of time when the AP 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 AP. 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 AP. (See the description for MultiPktDrop.)
