If the network has peer switches and the tunnel is established between

the APs managed by the peer switches then, when a switch managing

the home AP fails, the switch managing the association AP detects the

failure and terminates the tunnel. At this point the client is

disassociated. When the client re-associates it obtains a new IP

address.

If the switch managing the association AP fails, then the scenario is the

same as in item 1 above. The AP takes down all radios and the clients

disassociate.

L3 Tunnel

The L3 Tunnel feature allows mobile stations to maintain their IP connections while

roaming from one access point to another access point even when these access

points are attached to different IP subnets.

NOTE:

When L3 tunneling is enabled the VLAN ID is not used. In fact, the switch

puts the management VLAN ID, if any, on the tunneled packets.

NOTE:

If the wireless network topology changes (for example, a Unified Switch

reboots) while the L3 tunneling feature is in use, you should perform an

ARP refresh on wired clients to speed up the process of re-establishing

connectivity to the tunneled network.

L3 Tunnel Status

Display the status of L3 tunnel.

L3 Tunnel Subnet

Enter the subnet of L3 tunnel. The network IP address you enter in this field must

be in the same subnet as a routing interface for the WLAN on the Switch.

L3 Tunnel Mask

Enter the subnet mask for the network IP address on the L3 Tunnel subnet.

RADIUS Use Network

Configuration

This parameter is used to control whether the VAP uses the network or global

RAIDUS Accounting settings. Select

Enable

to use RADIUS accounting settings

defined on the Wireless Network Configuration page. Select

Disable

to use

RADIUS accounting settings defined on the Wireless Global Configuration page.

RAIDUS Accounting

Tick the check box to enable RADIUS accounting for wireless clients.

Security Option

Select the security mechanism of the wireless connection to protect the network.

None

Select this for not having any security of the network, and no further

options are configurable on the AP.
