#How to shutdown cisco virtual wireless lan controller upgradeIn all cases, customers should ensure that the devices to upgrade contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. In most cases this will be a maintenance upgrade to software that was previously purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:Īdditionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. #How to shutdown cisco virtual wireless lan controller installCustomers may only install and expect support for software versions and feature sets for which they have purchased a license. Note: Meshed mode is not enabled by default.Ĭisco has released free software updates that address the vulnerability described in this advisory. The following example shows a WLC configured for meshed mode:Ĭisco AP Identifier. To determine whether a WLC is configured for meshed mode, use the show ap config general command and verify that the AP mode is set to Bridge. Refer to the "Fixed Software" section of this security advisory for more information about the affected releases. #How to shutdown cisco virtual wireless lan controller seriesCisco Flex 7500 Series Wireless Controller.If an AP goes down, it can instruct nearby APs to increase their power levels to fill the coverage gap.This vulnerability affects the following products running a vulnerable version of Wireless LAN Controller software and configured for meshed mode: Due to the RF nature, the wireless access controller can easily detect interference between nearby APs and re-configure their power and channel settings automatically. It can accurately locate and identify each user. The self-configuring and self-healing wireless network is better for management and troubleshooting. ![]() ![]() ![]() Simplified Network Maintenance: Wireless LAN controllers eliminate site-surveys by including intelligent RF planning software. ![]() Enabling the centralized monitoring of the entire wireless infrastructure, which will decrease the total cost of ownership and unification of wired and wireless access, a future-proofing investment for upgrades. WLAN controllers, literally, "lock the air."Ĭentralized and Flexible Network Management: Centralized wireless controller provides flexibility for deployment, which will reduce overall budget, planning tools, and time spent organizing a wireless network in the business. Detecting and stopping unauthorized (rogue) APs to prevent all unauthorized wireless connectivity in the network. Instead of stopping the encryption at the AP, it helps to keep WLAN traffic fully isolated until it has passed through a firewall at the wireless access controller. Secured Wired and Wireless Network: Controlling wireless users' access privileges using a variety of deterministic criteria (authentication method, device type, application requested, etc.) to provide differentiated access to maintain security. What Are the Benefits of a Wireless LAN Controller?
