The difference between VLANs and VLAN interfaces

The difference between VLANs and VLAN interfaces

 An SVI [ switched virtual interface ] is normally found on switches (Layer 3 and Layer 2). With SVIs the switch recognizes the packet destinations that are local to the sending VLAN and switches those packets and packets destined for different VLANs are routed.

Note: An SVI cannot be activated unless the VLAN itself is created and at least one physical port is associated and active in that VLAN. Unless the VLAN is created there will be no spanning tree instance running hence the line protocol will be down for the SVI VLAN.



SW:

vlan 10-11

interface GigabitEthernet0/0
