Menu: Ethernet Statistics
You can view statistics on received and transmitted frames in two
ways:
❑ At the switch level, where you see the total of each frame type
on all ports taken together; or
❑ At the port level, further broken down into:
— Per port, all frame types
— Per frame type, all ports taken together
Statistics are a tool for diagnosing a problem and isolating it to a
specific port. You can view graphs that show information on the
switch as a whole. From this total picture, you have the option to
view statistics on a per-frame type or a per-port basis.

Displaying various statistics graphs does not require you to go
through a hierarchy of menus. Within a particular graph, you can
select to view statistics on a frame type, a port, or the entire system.
To illustrate, refer to Figure 4-4; it is the first graph Omega displays
when you select Ethernet Statistics from the main menu.
