• 00:0b:85:00:83:00 is the MAC address of the neighboring access point.
• Interface x is the interface number of the neighboring access point.
• 172.16.16.10 is the IP address of the access point’s controller.
802.11 MAC Counters
The following table describes the 802.11 MAC counters.
Table 2-19 802.11 MAC Counters
Counter Description
Tx Fragment Count This counter is incremented for an acknowledged MPDU with an
individual address in the address 1 field.
Tx Failed Count This counter increments when an MSDU is successfully transmitted after
one or more retransmissions.
Multiple Retry Count
(Graphics view only)
This counter shall increment when an MSDU is successfully transmitted
after more than one retransmission.
Invalid IP netmask (Text
view only)
This counter shall increment when an invalid IP netmask is transmitted
after more than one retransmission.
RTS Success Count This counter increments when a CTS is received in response to an RTS.
ACK Failure Count This counter increments when an ACK is not received when expected.
Multicast Rx Frame Count This counter increments when a MSDU is received with the multicast bit
set in the destination MAC address.
Tx Frame Count This counter increments for each successfully transmitted MSDU.
Multicast Tx Frame Count This counter increments only when the multicast bit is set in the
destination MAC address of a successfully transmitted MSDU. When
operating as a STA in an ESS, where these frames are directed to the
access point, this implies having received an acknowledgment to all
associated MPDUs.
Retry Count This counter increments when an MSDU is successfully transmitted after
one or more retransmissions.
Frame Duplicate Count This counter increments when a frame is received that the Sequence
Control field indicates is a duplicate.
RTS Failure Count This counter increments when a CTS is not received in response to an
RTS.
Rx Fragment Count This counter shall be incremented for each successfully received MPDU
of type Data or Management.
FCS Error Count This counter increments when an FCS error is detected in a received
MPDU.
WEP Undecryptable
Count
This counter increments when a frame is received with the WEP subfield
of the Frame Control field set to one and the WEPOn value for the key
mapped to the TA's MAC address indicates that the frame should not have
been encrypted or that frame is discarded due to the receiving STA not
implementing the privacy option.
