Comparison: Cisco Catalyst 9500 Vs Cisco Catalyst 4500 Vs Cisco 3850 Switches
Today I am going to talk about the fixed core chassis Cisco catalyst 9500 which Cisco released a month back. Cisco 9500 is actually enhanced version of Cisco catalyst 4500 chassis and also Cisco 3850 Switch. There are lot of other best features in Cisco 9500 Chassis as some of the features are just amazing in this device.
So we have Cisco 3850, Cisco 4500 Catalyst Switches, Cisco 6500 Catalyst switches, Cisco 6800 Catalyst switches and now Cisco 9000 catalyst switches with 3 flavours ( Cisco 9300 catalyst switches, Cisco 9400 catalyst switches and Cisco 9500 Catalyst switches)
How topology and the demand changes, below is the example topology showing the changes which leads to the next generation fabric network with cloud ready solutions and automation. CLI is gone for the campus fabric, All policy is driven with the SDN controller.
If we have Cisco 4500 and Cisco 3850 fixed chassis why we required Cisco 9500 chassis ?
I knew this is one of the question which you actually thinking and for this i would like to say that you need to understand the next generation campus requirements where customer wants to be have the smart campuses with much more features and future ready. With the help of Cisco 9500 catalyst switch, Cisco is going to leverage the programmability in their IOS-XE with UDAP 2.0 features.
The most amazing feature is encrypted traffic analytics, Yes with the help of Cisco catalyst 9500 switch you are going to have the analytics with even decrypted the traffic. Just wow...
Note: Make sure you are not going to confuse yourself with the Cisco Nexus 9500 Switches as they are different. These are Catalyst 9500 which is designed for Campus Fabric network with SD-Access Features. Both are different switches and will have used in different domains.

Cisco Catalyst 9500 Series fixed core switches are actually designed to help you change your network from a platform of connectivity to services. The first purpose-built platforms designed for full fabric-control with Cisco DNA and Software-Defined Access these switches deliver stellar performance and functionality and extend Cisco’s networking leadership with significant innovations in security, mobility, IoT and cloud.
Yes Cisco 9500 switch is dedicate and is used for the SD-Access environment where you are going to make your campus network as a fabric network and Automation, Analytics and Security with IOT features on top of it.
Do you know about SD-Access, Well I will come up with the SD-Access topic in another article where i will explain how transformation of the network from the VSS environment to the full fabric auto drive policy based network works.
Below is the comparison between the Cisco 3850 Fiber Switch with Cisco 4500-X and Cisco 9500 Fixed Chassis at the core in the campus network.

Please let me know your queries, I will come up with the post where i will going to define how to configure the SD-Access and how protocols work with L3 and L2 transport in the network.
