4-22 CHAPTER 4: MANAGING YOUR HUB USING QUICK CONFIG MANAGER

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.
