It manages the WLCs, their associated access points, and clients. Only one port is used at a particular point of time. Does the 4400 WLC route packets between VLANs? The reason for this is that, when a rogue AP is found, the finding AP disassociates the clients of the rogue AP, which causes denial of service to the clients. If a local net user is configured as a guest user, you must specify the life time, after which the user is automatically deleted. These are set at 1000 mbps, full duplex speed only.
