6509 used as non Core devices
Hi! Can someone clear this up for me I am quite confused. The 6509 is meant to be a core device since its so expensive and does switching and routing at fast speeds. However, in my organization they are using two 6509's as core devices and then cascading another two 6509's together providing access to workstations using blades. Is this correct to do? Shouldn't the 6509's be reserved for the core and less expensive switches be reserved as an access layer device for workstations? If so then why do they make 48 port blades for the 6509's?
