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
Statistics are useful if you are trying to diagnose a problem and
would like to isolate 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.
