The Cisco 8540 Wireless Controller is a highly scalable, service-rich, resilient, and flexible platform. It provides centralized control, management, and troubleshooting for high-scale deployments in service provide, enterprise, and large campus deployments.
[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.
In a corporate environment that requires strong security and the ability to block / allow a large variety of users, the Cisco Wireless platform excels. The system is extremely robust and can provide literally a blanket of coverage, with very good performance. They also offer external/out doors access points which provide excellent performance. Because the system is well built and designed, you often go through the lifetime of the product (you really need to apply updates) with very little issues. However, when you reach the end of the support life on the box, it is not cheap at all to upgrade/replace. You really need to keep an eye on the current life cycle and plan accordingly for a replacement date and fund.
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.
It's Cisco and like all our other Cisco products, chiefly switches, once you get it set up to your liking, it just runs itself after that. The reliability factor has been huge for us.
Ease in deploying new APs has been nice. We have a DNS record (and DHCP Option 43 as a fallback) that helps new AP find the WLC. The WLC takes it from there.
Good monitoring of connections, kicking people off, [and] blocking certain MACs are all useful features.
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.
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
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.
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.
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.
That was a great experience of having a new project and working on it. Although we got some hurdles and challenges but we overcome all the things and try to work efficiently for this. in this time Cisco support team also helps a lot an give pro tips which help us.
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 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.
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.
Positive impact 1. Our employees are able to move around anywhere in our 12-story building and have access to our corporate network. Employees are not tied down to an office and can easily move around to meetings and stay connected.
Because the equipment is so reliable, we do not have any unscheduled outages. Employees come in the building and connect without issues and have a sense that the wireless network "Just Simply Works."
When performing network maintenance, I usually have to block out several ours for our maintenance window. Upgrades sometimes do not go as smoothly as planned. This can be frustrating for the engineer.
