dvSwitch available ports
In the mastering Vsphere5 book by Lowe there is a paragraph describing the total and available ports on a dvSwitch. Book says a dvSwitch with 2 hosts would have 128 available ports. When adding a 5.0 or 5.1 dvSwitch in Vcenter and getting to the screen to choose which hosts to add to the switch there is a view settings link which when opened says 'max number of ports designated on this host', defaults to 256, what is this 256 as compared to the 128 he comes up with? He indicates no matter how many hosts you add to a dvswitch you will always only have 128 available ports.
