The mask assigned to the port.
Tx Packets
Number of packets transmitted.
Tx Dropped

Number of packets with transmission errors. This can be caused by: loss of carrier, no heartbeat, late collision, too
many retransmits (too many collisions when transmitting a packet).
Rx Packets
Number of packets received.
Rx Dropped
Number of received packets dropped.
Rx Errors
Number of packets received with errors. This can be caused by: overruns, unaligned frames, bad CRCs, frame
length violations, or late collisions.
Collisions
Collisions indicate how many times two stations tried to use the network simultaneously. A small number of
collisions is normal. A large number of collisions indicates that not enough bandwidth exists to support the traffic on
the network. This may be caused by connecting too many client stations to the network or by one or more client
stations performing continuous large data transfers. Either reduce the number of client stations or reduce the
amount of traffic being carried by the network. You could also define customer quotas to limit the amount of traffic.
