NOTE

Since frames vary in length, it’s best to look at the octet count to see how much traffic is passing through the hubs.

Statistic: Use ASor zto select the type of port statistics you want to view. Errors is the other type of statistic option you can view. See page 33.

Update interval: Use AS or zto select the time period between updates. For example, an Update interval of 5 sec. means the Console Manager collects and displays information from the Management Module every five seconds.

Speed: Displays the current speed of the hub in the Hub: field.

Type: Displays the manufacturer-assigned type of hub. You can change this to whatever you’d like through the System Configuration screen (see page 17).

%Utilization: The percentage of Ethernet bandwidth (10 or 100 Mbps) the device attached to that port is using. All hubs in the stack running at the same speed are in the same collision domain and share either 10 or 100 Mbps of bandwidth.

Collisions: The number of collisions detected. Collisions are normal in an Ethernet network. They tend to rise as network utilization rises.

Frames: The number of frames detected without errors. Includes unicast, broadcast, and multicast frames. Does not include frames received with frames too long, runt, FCS, or alignment errors.

Octets: The number of octets (bytes) contained in frames received that had no errors. This includes octets in unicast, broadcast, and multicast frames. It also includes octets after the start frame delimiter up to FCS, but not including FCS octets.
