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.
As an edge/WAN router that contains internet BGP routes, it handles this work very well. And the devices are robust, able to manage a significant load. However, the interface cost can be somewhat of a hindrance when wanting to use it to interconnect many metro clients.
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.
I would like to able to find more examples of configs. Given the multiple ways to configure the same setting, having a little more documentation would be helpful.
Juniper support is friendly, easy to understand, widely knowledgeable, and easy to get ahold of. I did not give them a higher rating as some of my more complex issues, were solved by myself while under consultation from Juniper TAC.
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.
The simplicity, elegance, and robustness of Juniper's solution make it much easier to troubleshoot and configure, when compared to Cisco Routers, especially considering Cisco's implementation of BGP (why are IPv4 and IPv6 linked in Cisco configuration?). Furthermore, the implementation of commit and rollback cannot be understated when compared to the Cisco solutions. This feature is a huge time saver when attempting to troubleshoot and remote configuration instances.
The stability and robustness of this solution provide a rock-solid foundation for all of our internet traffic.
The easy to use rollback and commit features simplifies remote administration and configuration, alleviating the need to travel to remote installation sites.
