Question: what is the difference between a default vlan and a native vlan?
Answer: Cisco books will often refer to the "default VLAN". The Default VLAN is simply the VLAN which all Access Ports are assigned to until they are explicitly placed in another VLAN. In the case of Cisco switches (and most other Vendors), the Default VLAN is usually VLAN 1. ... The Native VLAN can change.
