Logical and physical VLANs on the 4006 SupIII

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?

Re: Logical and physical VLANs on the 4006 SupIII

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

Then you can create logical VLAN interfaces

Repeat the above if you have more then one VLAN

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.
