Accelerate Technology Innovation at Your Access Layer with New Cisco Catalyst 9300 Switch Models


The Catalyst 9300 series switch line includes two new additions that are built from the bottom up for intent-based networks. Catalyst 9300 1G fiber switches provide a seamless migration path from Catalyst 3850 Fiber with a far better price-to-value ratio, avoiding cable upgrade costs, for a lower total cost of ownership. These new models extend the Catalyst 9300 series to desktop fiber applications and 1G fiber aggregation. Optimized for 1G cable access, the C9300L models are the fixed access replacement for the Catalyst 3650 series, with Fabric-in-a-Box capability making them ideal for business-critical branch office deployments. All of those new switches offer equivalent benefits of upper availability, higher speed and capacity, and more advanced security and programmability found within the remainder of the Catalyst 9000 family of switches.

Catalyst 9300 1G fiber - excellent for aggregation

By replacing your Catalyst 3850 switches with Catalyst 9300 1G fiber switches, you'll gain many security benefits common to the remainder of the Catalyst 9k family. This is important in a world where protecting your network is increasingly challenging due to the increasing complexity of the network, the increased scale of attacks, and the increased sophistication of the methods used by attackers.

New security solutions that you can use include MACsec 256 link encryption and encrypted traffic analysis (ETA). The Catalyst 9300 1G fiber switches also extend the SD-Access implementation. Cisco Switch Catalyst 9300 stacks can now be connected to extended nodes with the fiber interface.

Fiber to the Desktop is back with a bang

While running fiber to the desktop (FTTD) is not common practice, given the traditionally high cost of installing fiber cables, some network administrators find it to be the right solution for certain scenarios. These are situations in which high-speed connectivity and higher performance are demanded. In these cases, the 24-port and 48-port Catalyst 9300 1G fiber switches are an excellent choice to have at your disposal.

Here are some of the FTTD use cases:

  • High bandwidth applications such as media and entertainment.
  • Extreme physical conditions, such as manufacturing, where operating temperatures and cable lengths make copper less than ideal.
  • Use of low latency, such as financial trading desks.
  • Security sensitive facilities, where FTTD can reduce the risk of data loss and disruption.

Speaking of costs, it is important to consider more than just the cost of copper cabling compared to fiber optic cable. There's also the wiring closet, with all of your requirements for conditioned uninterruptible power supplies, HVAC costs, data grounding, and just plain extra space. When setting up a completely new network, FTTD can actually be very competitive with copper because the higher bandwidth and longer cable runs allow for a more optimized network design. Catalyst 9300 1G fiber switches provide the lowest total cost of ownership of any solution on the market today, as it is an integrated solution.

Catalyst 9300L for the critical business branch

The other new addition to the Catalyst 9300 series is a full complement of fixed uplink models, designated as the 9300L models. They are ideal for branch office deployments that need a critical level of security, reliability, and automation for the business. These switches provide a great balance between performance and cost, allowing you to stack up to 8 enclosures and provide a greater scale of performance and more advanced features than are available on the Catalyst 3650 switches they are intended to upgrade.

Software-defined access with a single box

With full SD-Access functionality, Catalyst 9300L switches provide fabric-in-a-box capability that allows you to implement a network fabric without the need for a second box to act as a controller. This gives you benefits like simplified provisioning, seamless roaming across the campus, and a consistent experience across wired and wireless domains.

New models, same advanced security and programmability

As more users bring more devices to connect to the network and more applications require more diverse access to the cloud, networks become more complex to manage and keep secure. These are the challenges we at Cisco are solving with the features found throughout the Catalyst 9000 family of switches. Catalyst 9300 1G fiber and Catalyst 9300L switches provide advanced functionality such as model-based scheduling capability, an out-of-box Python scripting guest shell, and application hosting, expanding the tools you have to manage and monitor your network. These switches also provide the power to use equivalent advanced security measures because the remainder of the Catalyst 9300 series, like MACsec 256 link encryption, encrypted traffic analysis, fully flexible Netflow, and reliable solutions.
