Switch ports
Switch ports are Layer 2 interfaces that are only associated with a physical port. The switch ports are used to handle the physical interface and associated Layer 2 protocols. They do not handle routing or bridging. Switch ports belong to one or more VLANs.
Modes VLAN switch ports
When you configure a VLAN, you must assign an ID number and can give a name if desired. The purpose of the implementations of the standard VLAN is associated with the private VLAN ports. Port is configured to send a frame to a specific VLAN. As mentioned above, the user can configure a VLAN mode to support voice and data traffic from voice coming from a Cisco IP phone. The user can configure a port that belongs to a VLAN by assigning a membership mode that specifies the type of traffic sent by the port and the VLAN to which they may belong. You can configure a port to support the following types of VLAN:

The user can configure a port that belongs to a VLAN by assigning a membership mode that specifies the type of traffic sent by the port and the VLAN to which they may belong. You can configure a port to support the following types of VLAN:
- Static VLAN: ports on a switch are manually assigned to a VLAN. Static VLANs are configured by using the Cisco CLI. This can also be carried out with the GUI management applications, such as the Cisco Network Assistant. However, a convenient feature of the CLI is that if you assign an interface to a VLAN that does not exist, create the new VLAN for the user.
- Dynamic VLAN: This mode is widely used in production networks and is not investigated in this course. However, it is useful to know what a dynamic VLAN. The membership of a dynamic port VLAN is configured using a special server called VLAN Membership Policy Server (VMPS). With the VMPS, the switch ports assigned to VLANs dynamically based on source MAC address of the device connected to the port. The benefit comes when you move a host from a port on a switch in the network to a port on another switch in the network. The switch dynamically assigns the new port to the proper VLAN for that host.
- Voice-VLAN: The port is configured to be in voice mode in order to be able to support an IP phone connected to it. Before you configure a voice VLAN on the port, you must configure a VLAN to a VLAN for voice and data. When first plugged a phone into a switch port that is in voice mode, it sends messages to the phone provides the configuration ID and proper voice VLAN. The IP phone voice tag frames with voice VLAN ID and sends all voice traffic through the voice VLAN.
