Field

 

Description

 

Number of TKIP packets that were resent to the AP by a client.

TKIP Pkt Replays

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

 

D-Link Technical Support.

 

 

 

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

CCMP Pkt Decrypt Err

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-idsession-idcommand 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.

 

 

 

Number of times radar caused packet errors. If this counter increments rapidly,

 

there is a problem in the RF environment.

Radio Recv Phy Err Ct

Note:

This counter increments only when radar is detected.

 

 

Rate-specific Phy errors are instead counted in the PhyError columns for

 

individual data rates.

 

 

 

Current power level set on the radio. If RF Auto-Tuning of power is enabled, this

Radio Adjusted Tx Pwr

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.

 

 

 

 

Number of packets for which the DWL-8220AP 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.

No Receive Descriptor

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.

 

 

 

Number of multicast packets dropped by the radio due to a buffer overflow on

MultiPktDrop

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.)
