When configuring VLANs, do I need to build the vlan database and configure the vlan interface for logical and physical vlans? The white paper said the phisical vlan was emulating a traditional router and the configuration example showed the following. conf t, int gig3/4, no switchport, ip address, and no shut. After following these steps, I cannot talk to that interface. Am I missing a step or just misunderstanding the instructions?
What you have configured on int gig 3/4 is a layer 3 interface. If you want a layer 2 port, you need to do create the VLAN in the VLAN database, then conf t, int gig3/4, switchport,switchport mode access, switchport access vlan and no shut
how are trying to talk to the interface ? It is regular Router port. So you have to connect to another switch or hub and connect your PC in the same subnet to able to ping it. If you need to ping different subnet then you need to configure default route on the Sup3.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
