Cisco 8540 Wireless Controller vs. Cisco Mobility Express (discontinued)

[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.

As it provides virtual WLC functionality, it has incredibly amazing built-in features that perfectly suit small to medium companies. It has the capability to manage the entire organization network seamlessly. It might be possible that it won't work smoothly and elegantly for large firms where there is a bulk amount of data bandwidth used.

• 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.

Incentivized

• Easy to setup
• Less maintenance
• Less disconnection

• 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.

• Honestly, I haven't found very many issues since we started using it, and I'm glad for that!

Very well made product. Very stable. We have had no issues administering the 8540.

Incentivized

We are using it 24x7 and it never hangs or create problems in connectivity.

After initial configuration and fixing minor issues with the firmware, the system worked really well, without any downtime. We were also satisfied with the throughput and range.

It is a better product. The evolution is positive.

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.

Cisco Mobility Express is far better than other products. It is a renowned brand in network products, and they are reliable and efficient as compared to other products that I have used so far. It is highly recommended.

• 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.

Incentivized

• It has given our IT team time back from not having to fix issues everyday with the network.
• It makes it easy for visibility of the network and allows those who are new to it to learn it quickly.
