Chose Cisco Catalyst 9800 Series Wireless Controllers
Compared to the previous Cisco 5520 and 5505 controller, 5508. The new Cisco Catalyst 9800 Series Wireless Controllers has been redesigned from scratch, Tag-based configuration is effective and transparent.
I would say the Cisco Wireless LAN Controllers would be a top contender as the best enterprise wireless controller that I have used. It has so many features and settings that can be controlled compared to other vendors. The newer Cisco 9800 is a different technology. At …
I think any size organization can benefit from them. The smaller "L" models work well for a smaller organization and of course, the same answer for the larger platforms. The failover/redundancy options are quite nice and the unified setup and UI is always nice for consistency.
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.
I think the updates are great. ISSU upgrading code is fantastic. I think the speed with which CAPWAP converges or reconverges, I think the redundancy mechanisms for roaming APs to other controllers is very good. I think overall, getting away from more of a monolithic processor where subprocesses handle what they call the WNCD tasks, I think fundamentally is an improvement in performance.
The radioactive tracing, all of the troubleshooting and all of the logging and all of the importing and exporting features for logging and analytics within the controller itself is really, really good compared to the predecessor AireOS.
The only downside I would say is the GUI performance is a little bit slow, even with a newer 9800, performance still lags a bit even compared to the previous generations. So I would like to see that improved. But aside from that, that's really the only issue that we have with it.
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
Despite common software and hardware issues this is still the best product on the market for large scale enterprise deployments. Cisco has worked with us extensively to reduce the amount of bugs in every iteration however new bugs are introduced or new incompatibilities always arise with major releases. Thus, while I'm hesitant to recommend the product it's still much better than all the other competitors such as Aruba and Juniper in the WIFi space. There is also extensive integration with DNAC/Catalyst Center and ISE in an SDA deployment. Recently there has been a number of critical issues with the controller software and Cisco has proved themselves to be incapable of timely troubleshooting and diagnosis. This has reduced our confidence in the product and it's current and future stability and maintainability. At it's current state the product is taking up too much of our engineering resources to maintain despite also paying for premium support from Cisco. As such I have reduced by rating as we are likely to look at alternative vendors for our long-term wireless management solution
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.
Due to our HA set up we have always managed to access our wireless networks without problems, when issues occur. When we have lost access to the GUI, due to internal network problems, console access is always welcomed and brings with it the normal Cisco CLI syntax. From previous versions of CLI, it is now a lot simpler and reflects other Cisco products, making it easier to troubleshoot and navigate when necessary.
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.
Monitoring is very good Seamless integration with Cisco ISE RRM configuration very easy. It has REST API support IOS-XE is very powerful operation system. Multicasting and mDNS features are really good and very easy to configure. It supports Pyats and Genie so getting constructed data from python script calls very helpful.
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.
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.
Ubiquiti WLAN is very much a consumer platform. It is not production ready, it is buggy, it has issues. It is cheaper than Cisco, but you get what you pay for. Aruba doesn't integrate nicely with our existing largely Cisco based networks, so when time came to replace AireOS, the Cisco Catalyst 9800 Series Wireless Controllers came out on top.
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.
Positive impacts, yeah, is good to have a central location to control all these profiles for different countries and locations. And the drawback, like I said to you really because of the too many integrations that have a dependency on the software version. For example, Cisco ONE for Access have certain software that can run through and then this scatter center need to make sure it's working with the others APS version that is currently working. And we also, the Cisco Catalyst Center also have some kind another version of software that you need to support this controller. So it's like two tier three tiers of the software version that we need to match. Then only it can work.
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.
