Cisco is a name well known in the IT field. The technology is tried and true and they have built a reputation on a solid platform. Though many people do not like the cost of the devices and the continued fees associated with long term ownership, you get what you pay for. I dont hesitate to recommend Cisco because I know people will get a solid product that will last a long time.
If you've got a large network and are already using FortiGate firewalls or FortiAP access points, integrating FortiSwitch Secure Access Switches makes for one integrated solution. Previously we had Cisco switches that had to be configured and managed separately, which was always prone to error. Now that we have our entire network backbone on FortiNet devices, managing and configuring them is smoother. We are now able to see much clearer if there are any configuration issues between networking devices.
Easy setup and configuration. While the web UI has its quirks, setting up VLANs and other tasks which can be exceedingly complicated on other switches, are much easier on Cisco SG switches. You also have the ability to upload an existing configuration to switches, which can speed up the task of deploying many identical switches.
Features for the price. Getting a 48 port L3 switch with PoE+ for less than $2,000 is a great value.
Reliability. We have hundreds of the SG switches in dozens of client sites, many in harsh conditions, and they just keep going.
The web UI has taken a turn for the worse with the latest firmware on the SGx50 models -- the bifurcation between basic and advanced modes and the changes to the way VLANs are modified is a step backward in my opinion.
The power bricks on smaller models are enormous. I'm sure, however, keeping this circuitry external to the switch is what keeps my switches running year after year in hot environments.
Fans can be a bit loud on larger switches -- this is true of pretty much any 1U device though.
Cisco is more enterprise level, more reliable, and generally more feature rich but also very expensive. That being said old or refurbished Cisco switches are much more affordable and in comparison to even new switches from the competitor they are still a great value even though they are used. I like Ubiquiti switches as well but Cisco is usually better overall.
We have previously used both Cisco 220 Series and Dell PowerConnect 8000 Series switches that were managed separately from our firewalls and access points. The Cisco and Dell switch worked fine and we never had a problem with them, but it was always a hassle to have to make configuration changes since that would have to be done via separate GUIs. Having the ability to configure and manage firewalls, switches, and wireless access points all within one central GUI saves time and headache.
