There are some special roles that cannot be mixed with any other roles:. You will do that later. If you've been following my guidance all these years, then you will already have a detailed set of hierarchical Network Device Groups NDGs , such as those displayed in Figure 5.

The point is - let's ensure that these Cisco WLCs have their own group for a device type. With that group, we can ensure that a device administration policy set is built just for these devices and their unique way of doing Device Administration.

Click Add. Name the profile and add good description. I find it is always best to name the profile based on the device that will use it. Under Custom Attributes, click Add. Click Save. At any time, you can edit the Raw View, which is just text, as seen in Figure 9. Notice how each role number must increment role1, role2, role3. Many wired networks base the security on physical access control, trusting all the users on the local network, but if wireless access points are connected to the network, anybody within range of the AP which typically extends farther than the intended area can attach to the network.

Wireless access point

The most common solution is wireless traffic encryption. Modern access points come with built-in encryption. The first generation encryption scheme, WEP , proved easy to crack; the second and third generation schemes, WPA and WPA2 , are considered secure [5] if a strong enough password or passphrase is used. Opinions about wireless network security vary widely.

For example, in a article for Wired magazine, Bruce Schneier asserted the net benefits of open Wi-Fi without passwords outweigh the risks, [6] a position supported in by Peter Eckersley of the Electronic Frontier Foundation. The opposite position was taken by Nick Mediati in an article for PC World , in which he takes the position that every wireless access point should be protected with a password. From Wikipedia, the free encyclopedia. Not to be confused with Wireless Application Protocol.

When wireless devices are used for high bandwidth applications or concurrent use such as online testing, an even greater number of APs may be required to achieve a density closer to users per AP.

Retrieved March 17, Handbook of Research on Wireless Security. IEEE uses Most of us have seen or heard about We also have the Wi-Fi Alliance that helps with the promotion of wireless networking. For example, IEEE has described authentication and encryption in their These names are easier to work with than referring to It has some Ethernet ports to connect your computers and it has antennas for wireless users.

In reality, these components are all built into one device:. In small networks like this, the AP does everything by itself. We call this an autonomous access point.

It uses When we look at large Enterprise networks, a single access point is not enough. Imagine a network with hundreds or thousands of users. You want to have a stable wireless connection, wherever you go. Switching seamlessly switching from one access point to another is called roaming.

A single access point also has limited bandwidth.

If you have a meeting room with users then a single access point might be unable to provide enough bandwidth for everyone. Since we use wireless networking for our users, it has to be close to our users. How does this second access point know that you are already authenticated to the network?
