Virtual LAN (VLAN)

Note: Avoid assigning devices into VLAN 1 as it is the default management interface for all switches which introduces several security risks as it is the default interface to send out advertisements of Cisco Discovery Protocol (CDP) and VLAN Trunking Protocol (VTP). Change the default VLAN to any VLAN other than VLAN 1.
