Managing Ethernet MicroLAN Switches
5-4 Repeater Statistics
Statistics Defined
The Statistics window displays the statistical counts accumulated since the
Ethernet MicroLAN Module was last reset; the following information is
displayed:
Active Users
Displays the number of users (identiÞed by MAC [Ethernet] address)
communicating via a port on the Ethernet MicroLAN Module. For an individual
port, the number of Active Users can tell you whether the port is supporting a
station or trunk connection.
Bytes
Displays the total number of bytes Ð including error packets Ð that have been
processed by the selected repeater, board, or port. Note that this byte count
includes errors.
Broadcasts
Displays the total number of broadcast frames that have been processed by the
repeater, board, or port. Broadcast packets have a single address recognized by
each station on the net; this address is designated in IP address form as
255.255.255.255, or in MAC hexadecimal form as FF-FF-FF-FF-FF-FF. ARP and
RARP requests sent by bridges and routers are broadcast messages.
Packets
Displays the total number of packets processed by the repeater, board, or port.
Again, note that the packet count includes errors.
Collisions
Displays the combined number of transmit and receive collisions detected by the
repeater, board, or port. Transmit collisions are those the Ethernet MicroLAN
Module detects while transmitting a packet, which means the Ethernet
MicroLAN Switch has transmitted one of the colliding packets; receive collisions
are those detected by the Ethernet MicroLAN Switch while it is receiving a
transmission.
Hard Errors
OOW Collisions Displays the number of collisions out of the standard
collision window (51.2 µs) experienced by the repeater,
board, or port. Out-of-window collisions typically
indicate a network design ßaw.
Giants Displays the number of giant packets that the repeater,
board, or port has detected. A giant packet exceeds the
maximum Ethernet frame size of 1518 bytes (excluding
the preamble).
