configured static IP address is already being used by the Wireless feature then the Wireless
feature is not disabled and service to the wireless clients is not interrupted.
When Wireless Switches enables IP tunneling for wireless clients, the MAC of the wireless tunnel
client has the highest priority. MBA and IMPB will not work to limit the wireless tunnel client MAC.
IP Tunnel versus MBA and IMPB
In addition, when a wireless tunnel client is added by Wireless Switch, the Wireless Switch will
notify the MBA module to remove the client MAC if it added the MAC.
In other words, MBA and IMPB will not work when the MAC belongs to a tunnel client.
To achieve IP-in-IP tunnel forwarding, the MAC addresses of the devices under the tunnel are
learned and marked as “static” FDB entries on the Wireless Switch. These “static” entries would
not be removed using the “clear fdb all” command nor can they be erased by using the “delete fdb
<vlan_name> <macaddr>” command. They also would not aged out from the FDB table as long as
the devices are still online.
