Configuring Mobility Domains
Before configuring a mobility domain, you should determine the userVLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.(s) for which mobility is required. For example, you may want to allow employees to be able to roam from one subnetwork to another. AllManaged devicesthat support theVLANsVirtual Local Area Network.

Amanaged devicecan be part of multiple mobility domains, although it is recommended that amanaged devicebelong to only one domain. Themanaged devicein a mobility domain do not need to be managed by the sameMobility Master.
You configure a mobility domain on aMobility Master; the mobility domain information is pushed to allmanaged devicethat are managed by theMobility Master. On eachmanaged device, you must specify the active domain (the domain to which themanaged devicebelongs). If you do not specify the active domain, themanaged devicewill be assigned to a predefined default domain.
The basic tasks you need to perform to configure a mobility domain are listed below. The sections following describe each task in further detail.
You can enable or disable IP mobility in a virtual AP profile (IP mobility is enabled by default). When you enable IP mobility in a virtual AP profile, theESSID扩展服务集标识符。ESSID refers to the ID used for identifying an extended service set.that is configured for the virtual AP supports layer-3 mobility. If you disable IP mobility for a virtual AP, any clients that associate to the virtual AP will not have mobility service.
Listed below are the steps to configure and join a mobility domain:
Configuring a Mobility Domain
You configure mobility domains onMobility Master. Allmanaged devicesmanaged by theMobility Mastershare the list of mobility domains configured on theMobility Master. Mobility is disabled by default and must be explicitly enabled on allmanaged devicesthat will support client mobility. Disabling mobility does not delete any mobility related configuration.
The home agent table maps a userVLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.IPsubnetSubnet is the logical division of an IP network.to potential home agent addresses. When you enable mobility themanaged deviceto which the client connects for the first time becomes its home agent. The mobility feature uses the home agent table to locate a potential home agent for each mobile client, and then uses this information to perform home agent discovery. To configure a mobility domain, you must assign a home agent address to at least onemanaged devicewith direct access to the userVLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.IPsubnetSubnet is the logical division of an IP network.. (Some network topologies may require multiple home agents.)
It is recommended that you configure the switch IP address to match the AP’smanaged device, or define theVRRP虚拟路由器冗余协议。VRRP是一个避署ction protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN.IP address to match theVRRP虚拟路由器冗余协议。VRRP是一个避署ction protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN.IP used formanaged deviceredundancy.

The mobility domain nameddefaultis the default active domain for allmanaged devices. If you need only one mobility domain, you can use this default domain. However, you also have the flexibility to create one or more user-defined domains to meet the unique needs of your network topology. Once you assign amanaged deviceto a user-defined domain, it automatically leaves the default mobility domain. If you want amanaged deviceto belong to both the default and a user-defined mobility domain at the same time, you must explicitly configure the default domain as an active domain for themanaged device.

Ensure that theESSID扩展服务集标识符。ESSID refers to the ID used for identifying an extended service set.to which the mobile client will connect supports IP mobility.

If you disable IP mobility for a virtual AP, any client that associates to the virtual AP will not have mobility service.
Joining a Mobility Domain
Assigning amanaged deviceto a specific mobility domain is the key to defining the roaming area for mobile clients. You should take extra care in planning your mobility domains and survey the userVLANsVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.andmanaged deviceto which clients can roam, to ensure that there are no roaming holes.
Allmanaged deviceare initially part of the default mobility domain. If you use the default mobility domain, you do not need to specify this domain as the active domain on amanaged device. However, once you assign amanaged deviceto a user-defined domain, the default mobility domain is no longer an active domain on themanaged device.
The following procedure describes how to activate a mobility domain:
1.In anode hierarchy, select a device navigate to>page and select thetab.
