I have CME with 500 express switch. I setup two vlan one for voice and the other for data. I need to add second data vlan to the CME which has couple of server and PCs in that vlan. sub-interface for the second data vlan can't accept "native" keyword because first data vlan is already native vlan, and without "native" keyword, the PC connected to switch port belong to that VLAN doesn't have access to sub-interface and therefore no internet connection.
any help as far as native vlan, and how to setup second data vlan with 500 express switch would be very appreciated.
