{

Tx Discards Wrong Source Address—Number of transmit requests that were discarded

because the source address is not equal to the MAC address.

{

Tx Retry Limit Exceeded—Number of times an MSDU is not transmitted successfully because
the retry limit is reached, due to no acknowledgment or no CTS received.

{

Tx Multiple Retry Frames—Number of MSDUs successfully transmitted after more than one
retransmission (on the total of all associated fragments). It may be due to collisions, noise, or

interference. Excessive retries can indicate that too many computers are using the wireless

network or that something is interfering with transmissions.

{

Tx Single Retry Frames—Number of MSDUs successfully transmitted after one (and only one)
retransmission (on the total of all associated fragments). May be due to collisions, noise, or
interference. Large numbers of single retries can indicate that too many computers are using

the wireless network or that something is interfering with transmissions.

{

Tx Deferred Transmissions—Number of MSDUs for which (one of) the (fragment)
transmission attempts was one or more times deferred to avoid a collision. Large numbers of

deferred transmissions can indicate that too many computers are using the wireless network.

Reception List
Reception statistics are not available for MSM devices running software version 5.3.x.

{

Rx Packets—Number of packets received.

{

Rx Dropped—Number of received packets that were dropped due to lack of resources on the
AP. This should not occur under normal circumstances. A possible cause could be if many

wireless clients are continuously transmitting small packets at a high data rate.

{

Rx Multicast Octets—Number of octets received successfully as part of multicast (including
broadcast) MSDUs. These octets are MAC header and frame body of all associated
fragments.

{

Rx Unicast Octets—Number of octets received successfully as part of unicast MSDUs. These
octets are MAC header and frame body of all associated fragments.

{

Rx Fragments—Number of MPDUs of type data or management received successfully.

{

Rx Multicast Frames—Number of MSDUs, with a multicast MAC address (including the
broadcast MAC address), as the destination address, received successfully.

{

Rx Unicast Frames—Number of MSDUs, with a unicast MAC address as the destination
address received successfully.

{

Rx Discards No Buffer—Number of received MPDUs that were discarded because of lack of
buffer space.

{

Rx Discards WEP Excluded—Number of discarded packets, excluding WEP-related errors.

{

Rx Discards WEP ICV Error—Number of received MPDUs that were discarded due to
malformed WEP packets.

{

Rx Message in Wrong Message Fragments—Number of MPDUs of type data or
management received successfully, while there was another reception going on above the

carrier detect threshold but with bad or incomplete PLCP preamble and header (the message-
in-message path #2 in the modem).

{

Rx Message in Message Fragments—Number of MPDUs of type data or management
received successfully, while there was another good reception going on above the carrier

detect threshold (the message-in-message path #2 in the modem).

{

Rx WEP Undecryptable—Number of received MPDUs, with the WEP subfield in the frame
control field set to one, that were discarded because it should not have been encrypted or

due to the receiving wireless client not implementing the privacy option.
