Cisco Catalyst 9400 Series Switches are well suited for data closets in today’s ever expanding network system requirements. Today’s businesses rely on stable, fast, and highly available data connectivity. Businesses perform at such a quick pace now and the need to consume data resources is an integral part of most every business function. There can no longer be outages. Slow data connectivity and sluggish system response is directly related to business success. The Cisco Catalyst platform has provided our company with a network foundation that is fast and reliable so that the business can concentrate on what they do best.
Cisco FabricPath seems to be well suited for larger datacenters where you need the scalability and flexibility that's provided. We've been able to provide our customers with much more bandwidth than they previously had throughout our datacenter and with applications generating much more east/west traffic now rather than large volumes of north/south traffic FabricPath and the nexus switches have given us the ability to provide our customers with the bandwidth that's needed to serve today's applications.
The Cisco Catalyst 9400 Series Switches provide reliable connectivity for multiple client device types whether computers, phones, wireless access points, etc.
The Cisco Catalyst 9400 Series Switches has deployment flexibility from traditional IOS-XE deployments to Cisco Catalyst SD-Access and now Meraki monitored solutions.
Multiple switch models allow us to customize each data closet deployment to exactly fit the port density and power-over-Ethernet requirements.
It's been fairly easy for people to learn and work with.
It has simplified network administration by utilizing Fabric Extenders which are all configured from the same switch and treated as an extension of the switch rather than as a separate entity.
Software needs improvement, where features are added (Stack wise) or removed (GLBP) without solicitation from a wider audience or depreciation, respectively
Software bugs recently in basic features like AAA
Ability to turn off all unused services or features to reduce the attack surface
Cisco CoPP functionality is not like it was on the Cat 6k platform - users cannot create custom policies for use at the control-plane interface
The Catalyst switches definitely have a more robust feature set than the Meraki switches but the Meraki switches are intended for a different use case than the Catalyst switches. We used Catalyst switches in our wiring closets because they fit in better with the topology and feature sets that we wanted to deploy.
In comparison to Cisco ACI, Cisco Catalyst, and Juniper EX Switches the Nexus switches have stood their ground and we've been fairly happy with them. I like that similar to Cisco's ACI and the Juniper EX switches that I've worked with I can manage multiple chassis from one place. ACI can do this on a much larger scale though. I think Juniper limited the number of devices in a single virtual chassis to 10 or less depending on the device type. ACI can do a few hundred leafs plus their fabric extenders so if you're looking for one place to manage all your devices it can scale well beyond either the Cisco FP or Juniper EX series switches, but it also has a much steeper learning curve and completely different interface. The loop prevention built into FP has been a great improvement vs our old Catalyst switches.
Stability - even 10 year old devices are still running and doing the job
Sometimes lines of products are on the market for a very short time (eg. 6800 instant access) - it is hard to buy equipment to make the network bigger.
FabricPath is easy enough to learn that the adoption on the team has been fairly quick. This allows us to quickly troubleshoot and allows us to meet and beat SLAs that demand we maintain 99.99%+ uptime for our paying customers.
