contain information such as the company logo and network usage policy.
Note: The wireless client is redirected to the external Web server only once while it associated
with the AP.

Wireless ARP
Suppression Mode
EnablethemodetoallowAPstoreducethenumberofbroadcastedARPrequestsonthe
wirelessinterfaces.Reducingbroadcastshelpsconservepoweronthewirelessclients.
The wireless clients that use power-save mode must wake up and use more power when
they detect broadcast frames.
Note: Enabling this feature slightly degrades AP packet forwarding performance due to extra
packet ltering to nd DHCP packets and extra processing for ARP request and reply packets.
Networks that do not use IPv4 should not enable this feature.
L2 Distributed
Tunneling Mode
The distributed L2 tunneling mode supports L3 roaming for wireless clients without
forwardinganydatatractotheUniedWirelesscontroller.Usethemenutoenableor
disable the mode.
L2 tunneling is recommended when the Unied Wireless controller does not support
hardware forwarding acceleration or hardware-based L2 tunnels.
Note:
1 - When there is only one controller managing all APs and that controller goes down, all APs shut
down their radios and the tunnel is terminated. After the controller recovers and the AP becomes
managed again, the client that was previously tunneling trac will re-associate and obtain an
IP address on the network where its currently located. This IP address will be dierent from the IP
address it was using when it was tunneling, and the trac will not be tunneled.
2 - If the network has peer controllers and the tunnel is established between the APs managed by the
peer controller then, when a controller managing the home AP fails, the controller 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.
3 - If the controller 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.
