I am finding it difficult to locate mac addresses for PC's and Printers when they are not assigned to a particular VLAN. When I run the cmd show fdp (mac address), nothing shows. I have deleted all ports from the default vlan. I do have the ports on a VOIP vlan also so I can find the mac for the phone but I am unable to find the mac of the other devices. The switches are Extreme 5420's running EXOS. Any ideas?
