Working with Network Plans 75Nortel WLAN—Management Software 2300 Series Reference GuideCreating a Network DomainWSS Software Version 4.1 and higher allows functionality found in Mobility Domains to be extended over amultiple-site installation, in a Network Domain. A Network Domain is a group of geographically dispersed MobilityDomains that share information over a WAN link. This shared information allows a user configured in one MobilityDomain to establish connectivity on a WSS in a remote Mobility Domain. The WSS forwards the user traffic by creatinga VLAN tunnel to a WSS in the remote Mobility Domain.In a Network Domain, one or more WSS switches acts as a seed device. A Network Domain seed stores informationabout all of the VLANs on the Network Domain members. The Network Domain seeds share this information amongthemselves, so that every seed has an identical database.(For more information, see the “Configuring Network Domains” chapter of the Nortel WLAN Security Switch 2300Series Configuration Guide.)To simplify configuration, WLAN Management Software assumes that the extent of the Network Domain is the same asextent of the entire network plan. WLAN Management Software also automatically sets the seed affinities on eachswitch as described in Table 2.1 Select the Configuration tool bar option.2 In the Organizer panel, select the network plan name.3 In the Task List panel, select Network Domain.4 In the Network Domain Name box, type the name for the Network Domain (1 to 60 characters, with nospaces or tabs).5 Click Next.6 In the Available Devices list, select the WSSs you want to use as the Network Domain seeds.Table 2: Affinities for Network Domain SeedsAffinity Value Assigned To...10 The switch itself, if it is a Network Domain seed.8 Another switch in the same Mobility Domain, if that switch is both aNetwork Domain seed and the seed switch for the Mobility Domain thetwo switches are in.5 All switches that do not fit either of the descriptions above.Note. Nortel recommends that you allow WLAN Management Software to automaticallyassign affinity values instead of using the CLI to manually set them. If you use the CLI to setthem, WLAN Management Software does not replace the affinity values it automaticallysets with values set on individual switches. Thus, if you accept network changes thatinclude Network Domain affinity changes, WLAN Management Software ignores the affinitychanges and overrides them with auto computed values. As a result, WLAN ManagementSoftware might generate local changes.
