What does wlc consist of

Local Net users are not automatically deleted. You have to delete them manually. In order to remove a user, place the mouse over the icon and click Remove. If a local net user is configured as a guest user, you must specify the life time, after which the user is automatically deleted.

The configurable range is between 60 seconds and seconds. Mobility group is a group of WLCs configured with the same Mobility group name. The client can roam seamlessly between the WLCs in the same mobility group.

WLCs in a mobility group provide for redundancy among themselves. You can place up to 24 regular WLCs Cisco , , and series in a single mobility group. Therefore, up to a maximum of access points APs are supported in a single mobility group. Note: Internet Explorer 6. These WLCs can be of different mobility groups. The major differences between the and Series WLCs are in the features they support. However you can't assign default gateway to the clients.

Yes, this can be done with the - hyphen key. Use this key to re-enter the previous parameter value. Instead of entering the username as admin , you enter it as adminn. In order to correct this, enter - hyphen key at the next prompt, then click Enter.

The system returns to the previous parameter. An user can enter only 31 characters. Currently there is no workaround for this. When enabled, the Management via Wireless feature allows a wireless client to reach or manage only the WLC to which its associated access point is registered. This is implemented for security, and recently was tightened down to just the one WLC in order to limit exposure.

This feature is supported for all management tasks, except uploads to and downloads from transfers to and from the WLC. Note: When you enable this option, you can expose the data. Ensure that you have enabled a proper authentication and encryption scheme. Yes, it is possible to create a mobility group between a Catalyst Switch with an integrated controller and a WLC. These are the 2 basic requirements that need to be maintained when you use mobility anchor in order to configure WLCs for guest access.

Note: You can configure configure redundant anchor WLCs. Proprietary features reduce the chance of interoperability between third party devices. These are the proprietary features of Cisco:.

Aironet IE - Aironet IE contains information, such as the access point name, load, number of associated clients, and so on sent out by the access point in the beacon and probe responses of the WLAN.

CCX clients use this information to choose the best access point with which to associate. MFP: Management Frame Protection is a feature introduced to protect the management frames, such as de-authentication, disassociation, beacons, and probes wherein the access point adds a Message Integrity Check Information Element MIC IE to each of the management frames.

Click the WLAN to which the client wants to associate. Short Preamble—A short preamble improves the throughput performance and is enabled by default. Certain devices, such as SpectraLink Phones can work only with long preambles. In such cases, it helps in association to uncheck short preambles. Then click the Uncheck the Short Preamble box.

Note: Make sure that you have strong authentication mechanisms in place since unintended clients can associate to your wireless network. APs that are not part of your wireless deployment are called rogue APs. Rogue APs cannot be automatically blocked.

This must be done manually. 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.

This can cause legal issues if the AP of the neighbor is detected as a rogue, and its clients are denied service. The Series wireless LAN controller supports up to rogues, which includes acknowledged rogues, while the Series supports rogues.

HPOV can perform things such as running scripts to send email on receipt of particular traps. HPOV is a Hewlett Packard product range that consists of an extensive portfolio of network and systems management products.

HPOV is most commonly described as a suite of software applications which allow large-scale system and network management of an organization's IT assets. HPOV includes hundreds of optional modules from HP as well as thousands of third parties which connect within the well-defined framework and communicate with one another.

In controller software releases earlier than 4. The mechanisms aimed at optimizing the distribution of traffic between APs and wireless devices can recognize interference and by using radio triangulation mechanisms can locate geographically the devices. They are able to observe on the device the hardware status, the situation of the physical ports, and a summary of the Access Points APs connected anytime they want.

Traffic aggregation and processing for wireless devices function It is important to know that this function is not all the time performed inside the WLC, for this it will depend on the network architecture used.

Management and operation function These two functions enable you to utilize and manage the wireless local network in a much simpler manner. Local wireless function In the case of the radio features of wireless technology, it is preferable to utilize the coordination and protection mechanisms in the radio spectrum for more efficient use in a particular area. They all adhere to the All controllers have fast, optimized network performance.

Flexibility is also paramount. Cisco can help scale a small, medium-sized, or large enterprise network, whether your solution involves a cloud-based controller, or an on-premises controller designed to handle your organization's needs. Catalyst cloud controllers are able to be deployed in either the public or private setting. Security is another important consideration for any organization, with hacking and data breaches in the news every day. Cisco WLAN controllers battle all kinds of threats to your business based on user ID and location thanks to built-in security features.

Finally, Cisco provides simplicity. With a Cisco WLAN controller, your network has a centralized hub where you can manage and control your access points. Skip to content Skip to search Skip to footer. Contact Cisco. Get a call from Sales.

Does the size of a controller matter? The diagram below provides and visual layout of the logical interfaces and how they connect to the physical ports of a WLC:. Figure 4. In this case, the Distribution port is configured as an The management interface is the default interface used to access and manage the WLC. The management interface is also used by the access points to communicate with the WLC. A controller can have one of more AP-Manager interfaces which are used for all Layer 3 communications between the controller and lightweight access points after they have joined the controller.

For these models, under the Management interface settings , there is an option labeled Enable Dynamic AP Management , that allows the Management interface to work as an AP-Manager interface at the same time:. Figure 5. If more access points are installed, then multiple AP-Manager interfaces are required to be configured. The virtual interface is used to manage and support wireless clients by providing DHCP relay functionality , guest web authentication , VPN termination and other services.

The virtual interface plays the following two primary roles:. The virtual interface IP address is only used for communications between the controller and wireless clients. It never appears as the source or destination address of a packet that goes out through the distribution ports and on to the local network.
