Streamlines network operations with automation and visibility while initial setup complexity and code stability improve

Pros

"The VPC feature of Cisco Nexus is great because it provides an active-active way of forwarding the traffic and avoids blocking any of the links."

Cons

"Initially, the codes I received through ACI were quite unstable, causing me to frequently replace them, which led to significant issues."

What is our primary use case?

I use Cisco Nexus for our data center.

What is most valuable?

The VPC feature of Cisco Nexus is great because it provides an active-active way of forwarding the traffic and avoids blocking any of the links. It also helps prevent STP loops, which is a valuable feature. Additionally, Cisco Nexus allows me to connect additional devices, such as FEX devices, when we need to extend services or connect physical servers. This capability of connecting additional factors as uplinks to Cisco Nexus is very beneficial. Overall, it has helped streamline network-related operations with its automation and API capabilities. It provides visibility and configuration options, aiding significantly in network management initiatives.

Enhancing data center network efficiency with reliable security integrations and good switching

Pros

"Cisco Nexus provides a reliable switching platform for our data centers. "

Cons

"Cisco's security features are in line with other OEMs, however, for data center security in terms of layer seven security, we prefer to have different OEMs rather than relying solely on Cisco."

What is our primary use case?

We use Cisco Nexus as a switching platform in all our data centers. We are running dynamic routing protocols such as OSPF, IS-IS, and BGP. On a few platforms, we also use MPLS and LDP protocols, along with MP-BGP to facilitate network efficiency.

What is most valuable?

Cisco Nexus provides a reliable switching platform for our data centers. It allows us to run dynamic routing protocols and helps improve network efficiency with features like MPLS. 

Additionally, it supports integration with third-party security tools, which is advantageous for our network architecture. Security-wise, we utilize Cisco's solutions while exploring other vendor options too.

Offers the ability to segregate VLANs and networks

Pros

"The most valuable feature of the solution is to segregate the network."

Cons

"In my company, we encountered some challenges since the network was not stable. The network is unstable, making it an area where improvements are required."

What is our primary use case?

I use the solution in my company for interconnecting servers and the nodes with the core switch or distribution switch.

What is most valuable?

The most valuable feature of the solution is to segregate the network. Cisco Nexus is effective since we can segregate the VLANs properly. I have probably been able to understand that it is an effective tool.

Offers good processing power to users

Pros

"Cisco Nexus and Cisco Catalyst have processing power and offer good utilization of Cisco devices."

Cons

"As a device meant to lead the processes related to networking and troubleshooting, I feel both aspects can be described as areas with certain concerns where improvements are required."

What is our primary use case?

I work in a cyber security company. My company handles cyber security products as a part of networking. In the networking part, my company handles routers and switches, along with the configurations related to routing and switching areas, while taking care of network troubleshooting. As a network administrator, the aforementioned areas consist of my main tasks.

My company does not get to utilize the tool for our organization's data center architecture since we don't deal in the area of data centers. The tool is useful in the area of networking.

What is most valuable?

Cisco Nexus and Cisco Catalyst have processing power and offer good utilization of Cisco devices. Cisco Catalyst is defined on Cisco SD-WAN and Palo Alto. The processing power of Cisco Catalyst is good compared to that of Cisco Nexus. Additional features are available on Cisco Catalyst, and its ports offer higher speeds than those of Cisco Nexus. Cisco Catalyst on the cloud offers support in the areas attached to switches and interfaces, along with ports that are faster compared to Cisco Nexus.

Offer high performance capabilities and enables efficient data transmission and processing

Pros

"The in-service software upgrade (ISSU) feature is quite valuable."

Cons

"Currently, the switches don't behave like the 4500 switches in terms of acting as one physical chassis. So the multi-chassis PortChannel feature is not applicable in this case. Nevertheless, virtual port-channel feature covers this."

What is our primary use case?

We mainly use them as core network switches. They are configured as a VPC cluster, and we have distribution layer switches attached to both chassis with virtual port channels. Additionally, we have another VDC to connect all the access layer switches for user connectivity.

How has it helped my organization?

Line rate is very important for us. The resilience is improved as we have redundant supervisors on both chassis, and the benefit of connecting downstream with VPC bundles allows us to present it as one logical entity to the downstream switches and other devices that support link aggregation.

Enhances the management infrastructure, making it preferable for many clients

Pros

"The seamless integration of Nexus in the data center provides a scalable and stable solution."

Cons

"The interface integration of Cisco Nexus with AI can be improved for better infrastructure management."

What is our primary use case?

The primary use case is the implementation of the test data center integrated with ICI and some tools to manage data centers. The network architecture includes configuring the chassis of many virtual switches in the same physical chassis and connecting with management tools.

How has it helped my organization?

The seamless integration of Nexus in the data center provides a scalable and stable solution. It enhances the management infrastructure, making it preferable for many clients.

Offers good reliability and network efficiency

Pros

"The product's initial setup phase is very easy."

Cons

"The product's high price is an area of concern where improvements are required. Cisco Nexus should lower its current prices."

What is our primary use case?

Basically, the Cisco Nexus is an L3 switch, and it offers the capabilities of L2 and L3 switches. The product is used for server farm switches and core switches, where there are big servers and data flow.

What is most valuable?

The solution's most valuable feature is its ability to handle big data, involving a large volume of data ranging from 3,00,000 to 9,00,000. I have experience with three types of switches from Cisco Nexus, and I know that they can handle lots of data. You can use the features you want and stop the features you don't want.

A low-latency, high-density switch for general deployments and high-performance computing

Pros

"We've found their tech support to be excellent, especially in their willingness to resolve issues promptly."

Cons

"The scalability can be improved. "

What is our primary use case?

Currently, our infrastructure relies on hyper-converged technology, in conjunction with Cisco infrastructure, which is essential for our features. Spamify utilizes Cisco infrastructure for its functionality, while Linksys manages connections with other systems. Our servers handle computation, storage, and related technologies, while Cisco takes care of network functions, including routing and switching. We also employ Cisco's firewall for security purposes, both externally and internally. Now, we're in search of structural virtualization technology with security and virtualization capabilities for version 4.16.

What needs improvement?

The scalability can be improved.
