Doorbell Ringer/Chime: The sounding device that produces a ring, or chime or other type of sound when someone pushes the doorbell button. Some have a different ring/chime pattern depending on if the front or back door button is pushed.
All used ports are associated with VLANs distinct from VLAN 1 and distinct from the black hole VLAN. It is also a good practice to shut down unused switch ports to prevent unauthorized access. A good security practice is to separate management and user data traffic. The management VLAN, which is VLAN 1 by default, should be changed to a separate, distinct VLAN. To communicate remotely with a Cisco switch for management purposes, the switch must have an IP address configured on the management VLAN.
â¢ Dynamic VLANs: In a dynamic VLAN, the switch automatically assigns the port to a VLAN using information from the user device like MAC address, IP address etc. When a device is connected to a switch port the switch queries a database to establish VLAN membership. A network administrator must configure VLAN database of a VLAN Membership Policy Server (VMPS). Dynamic VLANs support instant movability of end devices.
