Enabling Multi-domain architecture from campus to cloud with Catalyst 9600

 

Campus Network environments are very diverse and constantly in a state of change. Today’s networks are extended across multiple sites, domains and geographies with complex networking infrastructure for wired, wireless and remote connectivity built on platforms of all types, makes and operating systems.

 

IT is looking for ways to simplify network design and deploy standardized products which will work together easily in the campus and allow seamless cross-domain integration across campus, WAN, data center and cloud to help lower operational cost, reduce time to deploy and maintain and improve end-to-end reliability of the network.

 

Catalyst 6000 has been known as a ‘Swiss army knife’ in the industry delivering the richest set of software and services such as full Layer2, Layer3, Multicast, ACL, QoS and MPLS L2/L3 VPN to address many use cases in the campus core.

 

Continuing the legacy of the Catalyst 6000 for innovation and industry leadership, Cisco has announced Catalyst 9600 next-generation modular core switches. These are purpose built for Cisco’s Intent Based Networking (IBN) at scale, delivering comprehensive security, high resiliency and automation powered by Cisco’s UADP 3.0 and IOS-XE. Cisco Catalyst 9600 enables multi-domain architecture by providing many key innovations under IBN along with high performance and flexibility of speed from 1G, 10G, 25G, 40G and 100G to suit any customers’ current and future campus needs.

Key innovations and deployment use cases addressed by Catalyst 9600 are as below:

 

IBN Innovations

 

Security: Segmentation and Policy, MACsec256, Trustworthy Solutions

Automation and Programmability: SD-Access, Embedded Wireless Lan Controller, NETCONF and YANG APIs, Application Hosting

Analytics: Application visibility with NBAR AVC, Flexible NetFlow, Streaming Telemetry

High Availability: In-Service Software Upgrade, SSO, Stack wise Virtual, GIR and Hot patching

 

 

Deployment use cases

 

  1. L3 Core, Distribution or Collapsed Core-Distribution

Three-tier campus design is most common in medium and large enterprises where scalability, flexibility and reliability of the network is of utmost importance. Conversely, two-tier designs are more suitable for smaller networks providing simplicity by combining the core and distribution layers.

 

Cisco’s Catalyst 9600 delivers the full suite of Layer2, Layer3, ACL, QOS and Multicast functionality along with pre-defined ASIC templates for core and distribution scenarios. It can be easily deployed as an L3 Core and a Distribution switch in a three-tier design or as a Collapsed Core-Distribution Switch in the two-tier design.

  2. L3 Core + MPLS-PE

In enterprise networks, MPLS provides network segmentation locally within a site or for geographically distributed sites over WAN in a scalable way.

Catalyst 9600 delivers rich set of MPLS features such as MPLS L3 VPN, L2 VPN and MPLS over GRE with up to 1024 VRFs.

Customers can deploy the Catalyst 9600 Switch combining L3 Core and MPLS PE functionality on the same switch to achieve better performance and scale and to simplify their network design across LAN and WAN.

 

  3. Fabric Border

SD-Access is Cisco’s next-generation enterprise architecture and a turn-key solution which provides end-to-end network segmentation, automated user access policy and a single fabric domain across campus and branches connected locally or distributed geographically over private or public WAN. By allowing seamless integration across Cisco SD-Access, SD-WAN and ACI solution, Cisco’s IBN architecture further extends end-to-end network segmentation and consistent security policies from campus, branch and WAN to private data center and cloud.     

 

With higher performance and scale using Cisco’s latest ASIC UADP 3.0 and 8 Core x86 CPU, better resiliency and integrated security, Catalyst 9600 is designed to deploy SD-Access Border functionality at scale.

In addition, Catalyst 9600 also supports standards-based Overlay and Control-Plane with VXLAN BGP EVPN as a ‘Do It Yourself’ solution which can be managed using standard tools and APIs.

 


“The exponential growth in both wired and wireless devices connecting to our network is driving a requirement for increased throughput, security, and reliability all the way back to the core. The Catalyst 9600 series switch is ideal for our needs because it delivers on Intent Based Networking requirements to ensure our network remains always on.”
