PXU (ProximUnify) Profile and VLAN Roaming

PXU (ProximUnify) Profile and VLAN Roaming
ProximUnify architecture enables VLAN roaming for both data and voice clients. VLAN roaming support is required when
a client device roams between APs connected to switches with different VLANs configured. IP Tunnels are used to
forward the STAs traffic to and from the Home of the STA. STAs are assigned Homes at certain APs. If the STA moves to
another AP where its VLAN is unavailable, ProximUnify facilitates a seamless roaming.

Wireless Domain Configuration

In order for the AP and ProximUnify to work together to support VLAN roaming, the administrator must first configure a
ProximUnify Profile and configure VLAN parameters on the AP. For more information on ProximUnify configuration and
management, refer to the ProximUnify User Guide.
Wireless Domain: Wireless Domain constitutes the host of ProximUnify devices servicing wireless APs which in turn
service wireless clients. These Wireless APs should be registered with ProximUnify and must be sending and
receiving information.
Converged Mobility (CMOB): AP feature that enables VLAN roaming for both data and voice (VoIP) clients.
Each AP registers with a ProximUnify Module. In order to provide redundancy, a Primary and a Secondary ProximUnify
Module may be configured for an AP to register with. If redundancy is not of so importance, only one of the two Modules
can be configured. Note that the redundancy is just for registration purposes and Tunnel information is not carried
forward or transferred between Primary and Secondary PXU Modules. Communication between ProximUnify Modules
and registered Access Points is secured using Diffie-Hellman for authentication and RC4 for encryption. The "Shared
Secret" is required to fulfil these requirements.
NOTE: A wireless client would not be allowed by an AP to enter the ProximUnify Wireless Domain, if the corresponding
PXU Module is not registered with the Current Master PXU Module.
During a PXU failover, the AP association with CMOB STA is delayed for sometime. There is no end-to-end connectivity
during this period. For more information, refer to the "ProximUnify User Guide".

Configuring the ProximUnify Profile

The PXU Profile tab allows you to configure the IP address and select the server status to enable or disable the profile.
The PXU Profile consists of two Modules, a Primary and a Secondary. Configuring the PXU Profiles on the AP allows the
administrator to define a profile for PXU Modules used by the system. For more information on configuration and
management, refer to the "ProximUnify User Guide".
