Unicast Shows the percentage of readable frames
received that are addressed to single devices.
Multicast Shows the percentage of readable frames
received that are addressed to multiple devices. The
total number of multicast frames is normally a small
percentage of the value seen for unicast (single
address) frames. A high level of multicast frames can
adversely affect network performance.
Broadcast Shows the percentage of frames received
which are addressed to all devices. The total number
of broadcast frames is normally a small percentage of
the value seen for unicast (single address) frames. A
high level of broadcast frames can adversely affect
network performance.
The values shown in the Frame Types pie chart are
per poll period, not per second. To change the poll
period, see “Accessing the Hub” on page 4-6 .
