3 CEE switch support VLANs Virtual Local Area Network (VLANs) provide the capability to overlay the physical network with multiple virtual networks. VLANs allow you to isolate the network traffic between virtual networks and reduce the size of administrative and broadcast domains. A VLAN contains end stations that have a common set of requirements that are independent of physical location. You can group end stations in a VLAN even if they are not physically located in the same LAN segment. VLANs are typically associated with IP subnetworks and all the end stations in a particular IP subnet belong to the same VLAN. VLAN membership is configurable on a per-interface basis. Data model There is no SNIA model for VLANs. Some aspects of the Distributed Management Task Force (DMTF) model have been considered while others are completely proprietary. The following detailed notes describe the class diagram as shown in Figure 30. • The VLAN is a collection of protocol endpoints defined at the scope of the switch and is represented by an instance of Brocade_VLAN associated to the scoping system, which is the Brocade_EthernetSwitch through Brocade_VLANInEthernetSwitch. • The property Brocade_VLAN.ElementName gives the VLAN's user-friendly name. • Each VLAN may contain zero or more members. Each VLAN member is represented by an instance of Brocade_VLANEndPoint. The composition is through Brocade_VLANEndPointInVLAN. • The member is also defined at the scope of the switch associated to the scoping system, which is the Brocade_EthernetSwitch through Brocade_EthernetSwitchHostedVLANEndPoint. • Each Brocade_VLANEndPoint instance represents a concrete Brocade_LAG or Brocade_LANEndPoint of a Brocade_EthernetPort that has been added to the Brocade_VLAN. This relationship between the Brocade_VLANEndPoint and the Brocade_LANEndPoint is represented as Brocade_VLANEndPointOfLANEndPoint. And the relationship between the Brocade_VLANEndPoint and the Brocade_LAG is represented as Brocade_VLANEndPointOfLAG. • There is one Brocade_VLANService instance per Brocade_EthernetSwitch. This hosting is represented by Brocade_VLANServiceInEthernetSwitch. • The capabilities of the service are represented by an instance of Brocade_VLANServiceCapabilities associated to the service through Brocade_VLANServiceElementCapabilities. The maximum number of VLANs that can be created on the switch and the methods supported by the service are reported in this capabilities instance. • Brocade_VLANService provides extrinsic methods to create and delete VLANs, and add and remove members from an existing VLAN. • Brocade_VLAN can be created using the Brocade_VLANService.CreateVLAN() extrinsic method. Refer to mof content for details on the parameters. • The path of the newly created Brocade_VLAN instance is returned in the output parameter VLAN. The Brocade_VLAN will be associated to the appropriate Brocade_EthernetSwitch instance on which it is defined. • Members may be added to an existing Brocade_VLAN instance using the Brocade_VLANService.AddMembers() extrinsic method. Refer to BrocadeLAG.mof for details on the parameters. 66 Brocade Network Advisor SMI Agent Developer's Guide 53-1002169-01
