Enabling L3 Roaming Criteria for DP

Using the layer 3 roaming feature, clients can roam across APs in the network (from one data plane to another data plane). This is typically required when the number of clients in the network increases and clients have to roam from a network that they were connected to, to another WLAN network with similar access settings. This feature enables seamless roaming and ensures session continuity between the client and the network.

NOTE
L3 roaming is only supported on vSZ-H and vSZ-E.

You can configure the roaming criteria for a DP so that it uses one of these two options - UE subnet or WLAN VLAN to access another DP to connect to, within a network. Before this, you must ensure that the L3 roaming feature is enabled in the DP.

  1. Go to System > Cluster.
  2. Select the L3 Roaming tab.
    The page with L3 Roaming settings appears.

  3. Select the Enable L3 Roaming check-box.
  4. You can edit the L3 Roaming settings by clicking Configure. The Edit L3 Roaming page appears.
  5. From Activate, you can enable the feature for the vSZ-D by selecting Enable or Disable from the drop-down menu.
  6. From the Roaming Criteria drop-down, select one of these options to define the data format to establish connection between DPs: UE Subnet or WLAN VLAN.
  7. Click OK.
You have successfully enabled L3 roaming, and also set the roaming criteria based on which DPs would connect within the network.
NOTE
A fresh controller software installation or upgrade from a version that does not support L3 roaming resets the L3 roaming configuration and it remains disabled. You must enable L3 roaming on a DP again.
