Hi [NAME],   Private vLAN that spans on two switches should be involving Trunking.    [URL]
Hi I m planning deployment of private vlan on my network but i m a bit confused.  I have a primary vlan 200 community vlan 201 isolated vlan 202 i have bunches of switch powerconnected 5548 that are interconnected through 2 force10 S4048-ON.  i have my workstation on switch SW1 and SW2 and my server on swtich SW3.  I want that all my server sees the workstation but none of the workstation sees each other.  in order to achieved that i guess i should put all the port on SW1 and SW2 on isolated vlan and the uplink  of both switch in prosmiscuous port.  But in this configuration does the workstation on SW1 will see the workstation of SW2.? indeed the traffic from one switch to the other one will pass through a prosmiscous port.  Am i doing a mistake?
