Cisco Nexus Room for Improvement
Practice Lead - Data Center Networking at a construction company with 5,001-10,000 employees
There is an ongoing problem with the limitation of the TCAM table, which is that it doesn't have enough memory to allow you to be really granular with your policy. Without enough memory, it requires manual manipulation if you exceed or get near to the TCAM limits. They have improved it, but in the early days, it took down some companies.View full review »
I'm not in a good position to comment on what might be lacking. I just use the Nexus switches, and I'm very happy to use the machines.
A lot of technologies and features are present on Cisco Nexus and I haven't had a chance to dive into all of them just yet.
We had some issues, strange issues with our firewall from Cisco, however, we resolved them with Cisco. They were very, very strange issues indeed. However, they seem to originate only on our site, and not from Nexus. From my point of view, I've never seen in 20 years, a single breakdown.
They should work to make the pricing more reasonable for the local market.View full review »
The licensing is very complicated. They should work to simplify it.
Every feature you want to use you have to pay for separately as an extra cost. The features should be bundled together. It sometimes causes us to have clashes with dealers.
We don't find that there's any difference between the Nexus and Catalyst solutions. It seems that just the marketing is somewhat different, even though they seem to be the same technology.View full review »
Manager IP Core and Transmission Networks at GO PLC
One of the biggest challenges, which I see is that there's a constant evolution in the product. For example, our configuration is based on what is known as traditional data center implementation. Today there is the ACI deployment and to implement, to migrate from one technology to another, that's challenging both from a configuration perspective and also from a cost perspective. We have had a problem in an order of a batch of optics, which is practically failing. So that was about the average of optics, which caused us quite some problem.View full review »
Network Manager at a financial services firm with 1,001-5,000 employees
I am looking for a GUI that goes alongside them and more SD-WAN built to their core switches.
I'm looking at changing our firewall estate, and at the same time, looking at integrating our firewalls with whatever our core switch solution is going to be. I can't necessarily do that with the costings of a Cisco organization, as they're too expensive.View full review »
The cost of the support can be improved. We had critical operations, and we needed 24/7 support for 365 days, which was quite expensive. We had to go for a very costly support contract, which was really a concern. The availability of spare parts, especially in a remote location such as Egypt, can also be improved.View full review »

Founder & CEO at a computer software company with 1,001-5,000 employees
They could improve on having different technologies between product models. The management dashboard could be better if it could handle the Catalyst and the Nexus at the same time. If Cisco could find management connectivity between the DMA center and the ACI connectivity this would be helpful.View full review »
Network Manager at a transportation company with 5,001-10,000 employees
The operating system needs to be improved. There should be stability in the operating system, and it should not have as many vulnerabilities.
It is very expensive. Its price could be better.View full review »
Cisco Nexus could also have better documentation.
Moreover, it would be nice if the solution offered multiple types of port support. It does not have, for example, a single switch for both internet and fiber ports.View full review »
