What is our primary use case?
I design, implement, and troubleshoot networks that use Cisco switches. I am involved in every part of the design, including wireless.
What is most valuable?
The biggest advantage of having this solution is that it is easy to find engineers, and they are cheaper than hiring HP engineers. HP engineers are difficult to find and you have to train them, which brings up the price of an HP solution.
What needs improvement?
Cisco switches are really expensive compared to other solutions, which is something that should be improved. They are almost double in price.
As of late, Cisco has been moving from one technology to the next and they don't support each other. If you want new features then you have to buy a new product and forget about the old one. This is from a licensing perspective. For example, the Cisco DNA license versus then Cisco One license are things that I don't know about.
I would like to see better compatibility between Cisco and other vendors. There are a lot of features that are for Cisco devices only, and when you bring in a second or third vendor there are a lot of problems. Fixing this incompatibility would be an improvement. I have not tried a lot of other brands, but I have connected both Huawei and Aruba Wireless with Cisco. Connecting Huawei with Aruba Wireless works well with no hangs. However, connecting Cisco and Huawei is terrible. Sometimes you have to restart one, whereas other times you have to restart the other. I do not recommend mixing equipment between these two companies.
For how long have I used the solution?
I have been working with Cisco Catalyst switches for close to 11 years.
What do I think about the stability of the solution?
If the switch is set up properly in the first place then you don't need to come back to do anything with it. This is especially true with the Catalyst 3750. It is the most stable thing in the world. I have found that some of the newer switches will hang or lose their configuration, but this never happened with the 3750.
For example, I have faced a lot of problems with the 3850, especially if there are Aruba access points. Sometimes, it will just reject the access point, although when I bring a new one, it will allow it. Sometimes the VLAN, itself, hangs. Then you can put in another VLAN and it will work. There are a lot of mysterious things that I could not find an explanation for.
What do I think about the scalability of the solution?
I have not faced any problem with scalability.
In my opinion, the Catalyst switches are for enterprise-level organizations with 5,000 or more employees. If there are 1,000 or fewer employees then any switch will manage.
Some of the places I have worked in had networks with 20,000 to 70,000 users.
How are customer service and technical support?
I have not contacted technical support from Cisco. I have friends and colleagues who have received support but I just keep reading, then trial and error until I get it. I wouldn't want to pay for support if I don't use it. The only time I would require support is a hardware failure.
I have worked on two projects in the past where support licenses were purchased for a year. What I found was that I could purchase four additional switches and in total, they would cost less than the support. Those switches then go into storage and if one of the others fails then a replacement is available. Ultimately, it is much, much cheaper.
Which solution did I use previously and why did I switch?
I have always used Cisco networking solutions, although we are opening a new branch and I think that this time, we will use HP. They do not want to pay one to two million dollars for IT infrastructure. With HP, if they have to pay half a million then they will approve it.
I have experience with a hybrid environment where it was a Cisco LAN and an HP Aruba wireless LAN, and I didn't like it. I was losing some great options. Based on that experience, I think that all of the hardware should be from a single vendor. Either Cisco all the way, or HP Aruba all the way.
How was the initial setup?
It is very easy and very straightforward to set up and deploy. It takes maybe 15 to 30 minutes to get it working.
What's my experience with pricing, setup cost, and licensing?
The price of Cisco equipment is very expensive and you have to pay extra for support.
What other advice do I have?
My advice for anybody who is implementing this solution is to design the system well before deploying it. You have to consider all of the aspects and all of the options. Always beware. If there is a 1% chance of failure then consider it to be a 90% failure rate because when it fails, you will have options. Always have a plan A, B, C, and D. In my experience, sometimes all of the plans will fail, and sometimes the first one succeeds.
I can't give them a perfect market but they undeniably are of good quality.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?
On-premises
