Overall Satisfaction with Cisco Catalyst 9800 Series Wireless Controllers

Our scenario has 2 WLCs in redundancy to cover in the event of a possible link or equipment failure, we used the WLC 2504 in the past and migrated a little over 1 year to the Catalyst 9800-L which currently supports up to 250 access points. Management is essential for our AP park at our headquarters with more than 70 access points. The WLC performs all the necessary settings on the access points when it is connected to the network. Our WLC sets the VLANs, security rules, authentication portal, and signal strength/range of the installed equipment. The configuration is quite simple and everything can be done via a friendly graphical interface.
  • 10G Uplinks to improve the performance of network traffic.
  • Supports up to 5,000 connected clients.
  • Supports up to 250 access points.
  • Visibility of applications transmitted by users/groups in vlans.
  • 1x authentication portal with radius.
  • Compact 1RU.
  • To support more access points and customers to manage, it is necessary to purchase another performance license that we have not purchased.
  • Artificial intelligence to manage and distribute the best signal to access points and users on the WLAN network.
  • Support for the new 802.11ac wave 2 protocol with gigabit ethernet.
We prioritize a scenario in high availability and redundancy with an active WLC and the secondary standby in order to prevent the wireless network from being inoperable. Our second redundancy in addition to the equipment is the internet links where we also have two. With two WLCs we have a secure and always available network.
As previously mentioned, we have no problems with inoperative WLC because we have two units in an active/standby scenario. The WLAN network is not essential for the company because many use notebooks and smartphones on the corporate network and need access to the internet at all times.
Our controller manages and automates the entire wifi network. We have automatic radio frequency control, access point range, 802.1x authentication, VLANs, DHCP server, visibility and control by applications in a layer 7 firewall, and also the quality of service, prioritizing certain sensitive traffic such as voice and video from our network. Our WLCs also manage to update the access points' firmware at the same time in the nighttime when there is no user connected.
I always recommend two Wireless Controllers (WLC) instead of a single one to think about the failover scenario. It is very important to think about this detail. Cisco Catalyst 9800-L Series Wireless Controllers is for small to medium scenarios supporting up to 300 access points to purchase the performance license. Licenses can be extended over time without any problems. As the company grows, we buy more and enable our access points.
