Mobile Client Roaming Locations

You can view information about where a mobile user has been in the mobility domain. This information can only be viewed on the client’s home agent.

In the WebUI

1.Navigate to the Monitoring > controller > Clients page.

2.Click Status. The mobility state section contains information about the user locations.

In the CLI

show ip mobile trail <ip-address><mac-address>

HA Discovery on Association

In normal circumstances a controller performs an HA discovery only when it is aware of the client’s IP address which it learns through the ARP or any L3 packet from the client. This limitation of learning the client’s IP and then performing the HA discovery is not effective when the client performs an inter switch move silently (does not send any data packet when in power save mode). This behavior is commonly seen with various handheld devices, Wi-Fi phones, etc. This delays HA discovery and eventually resulting in loss of downstream traffic if any meant for the mobile client.

When HA discovery on association is triggered, the foreign agent controller where the client is associated to, sends unicast request to all Dell controllers within the mobility domain to find if any one of the Dell controllers has the IP mobility state information of the client. Once this information is received, L2-GRE/IPIP tunnel is established between the foreign and home agent Dell controllers.

With HA discovery on association, a controller can perform a HA discovery as soon as the client is associated. This feature can be enabled using the ha-disc-onassocparameter in the wlan virtual <ap-profile>command. By default, this feature is disabled. You can enable this on virtual APs with devices in power-save mode and requiring mobility. This option will also poll for all potential HAs.

Setting up mobility association Using the CLI

wlan virtual-ap default ha-disc-onassoc

Configuring Advanced Mobility Functions

You can configure various parameters that pertain to mobility functions on a controller in a mobility domain using either the WebUI or the CLI.

In the WebUI

1.Navigate to the Configuration > Advanced Services > IP Mobility page.

2.Select the Global Parameters tab.

3.Configure your desired IP mobility settings. Table 156 describes the parameters you can configure on the Global Parameters tab.
