The Cisco 5520 Series Wireless LAN Controller is a highly scalable, service-rich, resilient, and flexible platform that is ideal for medium-sized to large enterprise and campus deployments.
Cisco 5520 Wireless Controller has better high availability features compared to the others. Also Cisco has a worldwide service center and is located in nearly all countries to offer fast and reliable support in case of any hardware issue. Also Cisco offers more features, for …
[The] best bet is the integration with ISE. Users use their active directory credentials to access the wireless and very simple guest portal to gain access to the Internet. We plan on integrating Cisco DNA Centre in the future that will give us more visibility and improved …
Cisco Wireless LAN controllers provide solid performance and security. Configuration can be overwhelming but if taken in small chunks is not that difficult to accomplish.
At this point the Cisco 5520 Wireless Controllers are end of life as a Cisco product, so I would not recommend them to anyone looking to purchase a wireless controller for an enterprise. However, many people are still using these, and they do work reliably, even if they are a bit long in the tooth now.
I believe that Cisco Wireless LAN Controllers are well suited for the enterprise environment for medium sized to very large companies. While there are smaller WLC appliances for smaller sized businesses, a case can be made for simpler or more cost effective wireless licensing solutions (e.g. Cisco Meraki). Cisco Wireless LAN Controllers are extremely well suited for dense deployments like stadiums, arenas, hospitals, theaters, and large offices because of their ability to support a large number of APs with a very diverse technology feature set.
We have had some issues with access points losing their configurations and going offline. This is not a common issue and we are not entirely certain if it is a fault of the controller or the individual APs. That said, the controller does not appear to retain the knowledge of the offline AP which can be a management headache.
Configuring wireless settings is very confusing because various settings are scattered all over the interface in different tabs
Lots of settings use Cisco's technical verbiage rather than common phrasing, so it's confusing what a lot of settings will do and requires researching the meaning before modifying the setting
The interface could be easier to use to do simple tasks such as reboot an access point
This equipment from Cisco has been dependable and we are able to easily continue to add access points or make changes easily to the Wi-Fi password settings.
We have been operating this equipment for a number of years and it does not give us any issues.
Although it is a very good product, support is easy and can manage by Level 1 support persons and downtime is too much less but still there is a cost factor matters which is consider by each organization. Furthermore, organizations also compare with other competitors so it is hard to pursue and defend the high prices.
Overall the usability is ok. The centralized management reduces complexibility and offers bulk features like adding access points to specific groups which automatically applies linked configurations.
On the other hand the GUI is very outdated and some features are not displayed correctly on new browsers. Also automation possibilities are very limited compared to the new 9800 series controller.
As I said before, the only thing we miss in our old model is the fact that the management interface never received an improvement in design. It has the same look and feels since it was launched. It's not that it's hard to use. It's just the case of could be modernized.
Downtime fear is the first fear which IT persons look and want to eliminate as much as they can but eventually you have to face it as nothing is perfect. Cisco Wireless Lan controller are feasible to use and easy to manage and other than this their issue reported are pretty low so you can get the best up time. now it also depends on scenario as well as environment.
Cisco Wireless Lan controller are feasible to use and easy to manage and other than this their issue reported are pretty low so you get the better uptime. if your get the uptime then it means its a stable product in your environment. Product performance also depends on the product management and Cisco Wireless Lan controller management is easy so you can get the great output.
Cisco support is always ready to support and engage in any problem or issue. Starting from the implementation support, troubleshooting any software issue or hardware. Their engineers are engaging whenever we ask for support, keep following up with us, and troubleshoot any problem till we find a solution and be satisfied [with] the service.
As usual, the support from Cisco's TAC (Technical Assistance Center) is lacking. Granted, they always get the job done, but the amount of lead time on a non-emergency is enough to make you just handle it yourself. The good news is that if you ask for Cisco's assistance and forget about it, they'll jump on by the time you've forgotten where you were in troubleshooting it and have it fixed for you.
Just take your time when setting up the HA pairs as those can be tricky. Also take your time setting up AP groups and make sure they are on all the SSIDs you need to be on.
Originally, when we deployed our first controller it was on a very limited basis. We only deployed it to our administration building and our High School. It was pretty straight forward. Because this was new to us we leaned heavily on our Cisco partner to assist us. With our last upgrade, we upgraded the controllers, added redundancy and expanded the building count along with new SSID's and restrictions. It went much easier, but again, we did rely on Cisco TAC and our partner to clarify and assist as needed. Having already been familiar with the product help tremendously.
Cisco Identity Services Engine is well integrated on Cisco 5520 Wireless Controller because the WLC supports a lot of authentication methods and security protocols (such as PEAP, EAP-TLS, Captive Portal redirect). They perform very well with ISE. Cisco ISE is able to manage centrally the AAA sessions from all the WLCs keeping a central point of management for wireless infrastructure.
The Aironet access points are used for employee WiFi access, and they integrate well with Meraki. They would offer a separate guest network, too, but the decision was made to physically separate the guest network, so even if a bad actor would gain access to the ethernet port of the AP, they'd still not see any company traffic.
Cisco is a brand name and people trust on it. if any one thing about the networking then Cisco is among those brand which is count as trusted brand and people rely on it. Also it support is good so people can use it. Cisco Wireless Lan controller are easy to use and manage so it requires less effort.
Implementing the [Cisco] 5520 [Wireless] Controllers offered us a huge improvement in administrative time over our previous Cisco 3850 deployment. Being able to see all of our APs on a single controller as well as centrally manage them is a great benefit. This also removed the need to deploy specific equipment in different IDFs throughout our Industrial locations and instead only requiring switches with Power Over Ethernet (POE) capability.
Wireless performance has improved with the deployment of our 5520s, which allows our plant operators to do their jobs more efficiently while on the move.
Having three Cisco 5520 Wireless Controllers provides tertiary redundancy for our wireless networks. The solution is elegantly simple. Preventing downtime is, obviously, a profound part of our supply chain capabilities.
We have had our [Cisco Wireless LAN Controller] 5508s for a very long time now and although they are getting dated, they have earned us our money's worth with consistency, stability, and ease of use. Users have minimal wireless complaints and when they do seldom are they WLC-related.
