Using the Console Interface309985-C Rev 00 3-41VLAN ConfigurationThe VLAN Configuration screen (Figure 3-17) allows you to assign VLAN portmemberships to standalone or stacked unit ports. You can also create port-basedVLANs and protocol-based VLANs:• Port-based VLANs allow you to explicitly configure switch ports as VLANport members.• Protocol-based VLANs allow you to configure your switch ports as membersof a broadcast domain, based on the protocol information within a packet.Protocol-based VLANs can localize broadcast traffic and assure that only theprotocol-based VLAN ports are flooded with the specified protocol-typepackets.When you configure ports as VLAN port members, they become part of a set ofports that form a broadcast domain for a specific VLAN. You can assign switchports, whether standalone or stacked unit ports, as VLAN port members of one ormore VLANs.You can assign VLAN port members attributes that allow the individual ports tooperate in accordance with the IEEE 802.1Q tagging rules. You can define each ofthe VLAN port members as tagged or untagged (see “IEEE 802.1Q Tagging” onpage 1-39 for a description of important terms used with 802.1Q VLANs).You can also use this screen to create and to delete specific VLANs, to assignVLAN names, and to assign any VLAN as the management VLAN.Choose VLAN Configuration (or press v) from the VLAN Configuration Menuscreen to open the VLAN Configuration screen.
