4.2.5.1 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 (WLAN) counters.
„ Reset Counters: Select this option to reset the counters.
4.2.5.1.1 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 medium. Frames discarded by the unit's hardware
filter are not counted by the Ethernet counters. For units with HW revision B and
lower, the maximum length of a regular IEEE 802.1 Ethernet packet that can be
accepted from or transmitted to the Ethernet port is 1514 bytes, excluding CRC
and VLAN(s). For units with HW revision C and higher, the maximum length of an
Ethernet packet that can be accepted from or transmitted to the Ethernet port
(excluding CRC) is 1600 bytes, including VLAN(s) for single or double-tagged
packets.
The unit transmits valid data frames received from the wireless medium to the
Ethernet port, as well as 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).
