Well, I used to test VLANs before. Here is what I did:
- If you use ISL for encapsulation, then you should not assign IP address to
the physical interface.
- If you use 802.1q for encapsulation, then you must assign an IP address to
the physical interface. This IP address (network) must be the management
VLAN/network (VLAN 1 by default). Also, the default-gateway is supposed to
point to the management VLAN, which is the IP address of the physical
interface.
