! Total received frames via Ethernet: The total number of frames
received from the Ethernet port. This counter includes both invalid
frames (with errors) and valid frames (without errors).
! Transmitted wireless to Ethernet: The number of frames
transmitted by the unit to the Ethernet port. These are generally
frames received from the wireless side, but also include frames
generated by the unit itself.
WLAN Counters
The unit submits data frames received from the Ethernet port to the
internal bridge, as well as self generated control and wireless
management frames. After a unicast data frame is transmitted, the unit
waits for an acknowledgement (ACK) message from the receiving unit.
Some control and wireless management frames, as well as broadcast
and multicast frames sent to more than one unit, are not acknowledged.
If an ACK is not received after a predefined time, which is determined by
the Maximum Cell distance parameter, the unit retransmits the frame
until an ACK is received. If an ACK is not received before the number of
retransmissions has reached a maximum predefined number, which is
determined by the Number of HW Retries and Number of SW Retries
parameters, the frame is dropped.
The Wireless Link Counters include the following statistics:
! Total transmitted frames to wireless: The number of frames
transmitted to the wireless media. The total includes one count for
each successfully transmitted unicast frame (excluding
retransmissions), and the number of transmitted multicast and
broadcast frames, including control and wireless management
frames. In the AU, there are also separate counters for the following:
# Beacons (AU only)
# Management and Other Data frames, including successfully
transmitted unicast frames and multicast/broadcast data
frames (excluding retransmissions, excluding Beacons in AU)
! Total Transmitted Unicasts (AU only): The number of unicast
frames successfully transmitted to the wireless media, excluding
retransmissions. This count is useful for calculating the rates of
retransmissions or dropped frames, since only unicast frames are
retransmitted if not acknowledged.
