Configuring VLANs Defining VLAN Groups Defining VLAN Groups VLAN groups increase network flexability and portability. For example, network users grouped by MAC address can log on to the network from multiple locations without moving between VLANs. VLANs can be grouped by MAC address, Subnets, and Protocols. Once a user logs on, the system attempts to classify the user by MAC address. If the user cannot be classified by MAC address, the system attempts to classify the user by Subnet. If the subnet classification is unsuccessful, the system attempts to classify the user by protocol. If the protocol classification is unsuccessful, the user is classified by PVID. This section contains the following sections: • Defining Protocol Based VLANs • Defining VLAN Protocol Ports Defining Protocol Based VLANs The Protocol Group Page contains information regarding protocol names and the VLAN Ethernet type. Interfaces can be classified as a specific protocol based interface. The classification places the interface into a protocol group. To define protocol based VLANs: 1. Click Advanced Setup > VLAN > Protocol Group. The Protocol Group Page opens: Figure 81: Protocol Group Page The Protocol Group Page contains the following fields: • Frame Type - The packet type. Possible field values are Ethernet, RFC1042, and LLC Other. • Protocol Value - User-defined protocol name. • Group ID - ID number assigned to frames containing specified protocol value The possible field range is 1 - 2147483647. • IP Address - Defines the IP address assigned to the VLAN group.
