Table 22-1 provides an overview of the types of VLANs you can use to logically divide the network. Table 22-1. VLAN Assignment VLAN Assignment Port-based (Static) IP Subnet MAC-Based Protocol Description This is the most common way to assign hosts to VLANs. The port where the traffic enters the switch determines the VLAN membership. Hosts are assigned to a VLAN based on their IP address. All hosts in the same subnet are members of the same VLAN. The MAC address of the device determines the VLAN assignment. This type of VLAN is useful when a host might not always connect to the network through the same port but needs to be on the same VLAN. Protocol-based VLANs were developed to separate traffic based on the protocol type before IP traffic became the de facto standard in the LAN. Use a protocol-based VLAN on networks where you might have a group of hosts that use IPX or another legacy protocol. With protocol-based VLANs, you can segregate traffic based on the EtherType value in the frame. Switchport Modes You can configure each port on a PowerConnect 8000/8100-series switch to be in one of the following modes: • Access - Access ports are intended to connect end-stations to the system, especially when the end-stations are incapable of generating VLAN tags. Access ports support a single VLAN (the PVID). Packets received untagged are processed as if they are tagged with the access port PVID. Packets received that are tagged with the PVID are also processed. Packets received that are tagged with a VLAN other than the PVID are dropped. • Trunk - Trunk-mode ports are intended for switch-to-switch links. Trunk ports can receive both tagged and untagged packets. Tagged packets received on a trunk port are forwarded on the VLAN contained in the tag. Untagged packets received on a trunk port are forwarded on the native VLAN. Packets received on another interface belonging to the native VLAN are transmitted untagged on a trunk port. 554 Configuring VLANs
