Site Survey Menu
The Site Survey menu displays the results of various tests and counters
for verifying the quality of the wireless link. These tests can be used to
help determine where to position the units for optimal coverage,
antenna alignment and troubleshooting. The counters can serve for
evaluating performance and identify potential problems. In the BU,
there is also an extensive database for the RB served by it.
The following sections describe each option of the Site Survey menu.
Traffic Statistics
The traffic statistics are used to monitor, interpret and analyze the
performance of the wired and wireless links. The counters display
statistics relating to wireless link and Ethernet frames. The Traffic
Statistics menu includes the following options:
 Display Counters: Select this option to display the current value of
the Ethernet and wireless link counters.
 Reset Counters: Select this option to reset the counters.
Ethernet Counters
The unit receives Ethernet frames from its Ethernet port and forwards
the frames to its internal bridge, which determines whether each frame
should be transmitted to the wireless media. Frames discarded by the
unit's hardware filter are not counted by the Ethernet counters. The
maximum length of a regular IEEE 802.1 Ethernet frame that can be
accepted from the Ethernet port is 1518 bytes. For tagged 802.1Q
frames the maximum size is 1522 bytes.
The unit transmits valid data frames received from the wireless media to
the Ethernet port, as well internally generated frames, such as
responses to management queries and pings received via the Ethernet
port. The Ethernet Counters include the following statistics:
 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.
