How do I graph
utilization on a
specific VLAN?
Select a device with ports which are members of target VLAN, and
choose to view History against the device. Select the appropriate VLAN
interface. These are easily recognized in the interface list by their interface
name - the name should include the keyword VLAN. Select an
appropriate sampling period from the History entries list, or create a new
entry if no suitable entries already exist. Choose the Load view and click
OK. Utilization for the selected VLAN across the sampling intervals chosen
will be graphed.
How do I view the
data associated with
an aggregated link?
An aggregated link is a composite of more than one physical link. 3Com
devices do not in general gather data for the aggregated link as a whole.
Instead, data is gathered against each component physical link.
If you select an aggregated link, and 3Com Network Director has
knowledge of the ports which comprise that link, then all ports which are
a member of that aggregation are presented on the menu.
In the example below, the link selected is an aggregated link from
140.204.232.73 Unit 1, ports 23 and 24 to 140.204.232.79 Unit 1, ports
11 and 12.

Select one of the listed ports to view data gathered for that port.
