Cisco 3504 WLAN Controller vs. Cisco 8540 Wireless Controller

I was given the task to setup a new wifi network in a very large building. With many departments and a complicated layout, we needed to have a solid router to handle all of the network traffic and throughput. I was given the task to find a reliable, robust and cost-effective solution. With the Cisco 3504 WLAN Controller, I was easily able to setup an autonomous access point with a few clicks. The cloud based controller software was easy to use and had many features I was able to utilize and control.

[Cisco 8540 Wireless Controller's] software quality has been shed in recent years. The only problem I have with it is its inability to work with older Cisco Access Points. However, that's to be expected for any deployment. While the controller's UI works well, some areas could be improved. API integrations lack flexibility. [I feel] it's time for policy redesign. It can be a little difficult to determine coding quality.

• [...] One thing which always fascinated me is the user interface because it is very friendly in nature.
• Also, with this tool, [my team and I] have started feeling more secure and safe because this platform does not require any such implementation. [A]ll the security patches happen on their own.
• One of the main pros of this app is that because it is so compact, it makes this platform a very good travel option. [I]t is also portable [and] can be easily carried anywhere.

• The GUI on the Cisco 8540 WLC is much better designed than other Cisco products. Its easy to navigate between the different settings to find what is needed.
• The AP groups allows touching multiple APs at one time.
• It also allows us to create standard SSIDs that can be used at all sites that connect back to it, this saves a lot of time instead of hitting each site with a local controller.

• The interface needs improvement, it is still complex to find some functions quickly
• The price of the product is still a big limiter
• The fragility of its physical structure, any impact, which is a little stronger, can cause damage to the product

• Code quality is a bit hit and miss. This will be great for a while, then things will be bad for a while, then we'll do it again. The UI of the controller works, but could do with a refresh, and I would like to see some improvement on layout and organization.
• The constant code/firmware upgrades and the QA of new code could be better.
• Maybe the compatibility with old Cisco Access Points could be improved, but it's normal in all kinds of deployments.

The GUI is easier to navigate as compared to the 2504. Also the responsiveness of the GUI, the quicker failover capabilities and the enhanced visibility are all major improvements over the previous generation WLC.

Cisco TAC is well known and SLA levels are great. Cisco support website and Cisco communities are another help for issues resolution. TAC is always supportive over Webex and helps to resolve issues pretty fast. This is another assurance for people to go with Cisco as the TAC capabilities are proven for all product lines.

It is a better product. The evolution is positive.

The main reason why our company chose to opt for the Cisco 3504 WLAN Controller was the magnificent quality-price ratio of the product. It is very easy to handle if you have the appropriate technical knowledge and if not, you will always have Cisco technical support supporting you for whatever you need. Once the product is configured, it works stably without intervention and is fully integrated with the company's other Cisco solutions.

We have [done] some work before with the Cisco 3504 product, but the more recent Cisco 8540 Wireless Controller provides a wider range of capabilities for managing the wireless network and each individual device [and] also being able to handle more users. Unfortunately, we didn't test and deploy equivalent products from other concurrent companies.

• The WLAN controller is a great tool for wireless network administration. With the Cisco Wireless Controller, we can quickly configure and manage all Cisco access points. It's also very easy to set up and manage. The Wlan Controller is a must-have for all our wireless network design.
• The WLAN Controller is a really useful device, it's easy to use and the setup is clear. The 3504 we use has 4 interfaces, we use 2 for data, one for management and one for failover. The wireless controller is very reliable, it will not let your network down. The only downside is that it can be a little bit slow when you need to add a lot of new access points.
• Cisco 3504 Wireless Controller is a great tool for managing WLANs. The controller allows you to manage a large number of access points and allows you to very quickly manage and configure all devices in the network and have one of the most important components of the system. The controller is easy to use and supports a large number of connections and devices.

• The Cisco 8540 Wireless Controller allows you to reduce your hardware footprint of wireless controllers deployed in your environment. Instead of having a controller per site deployed, you can have a couple of 8540 controllers in your data center that can handle up 6000 Access Points.
• Some of the savings on hardware cost is offset by the cost of redundant WAN circuits. The access points will continue to function when connectivity to the Cisco 8540 Wireless Controller is unreachable, but it will not allow any new connections in that wireless environment.
