Always-on wireless network with stateful switchover when wireless functionality is enabled on stack of
Catalyst 9300 Series Switches.
Deep buffer technology
The Catalyst 9300 Series higher-scale models have a deeper buffer to address the requirements of rich multimedia
lossless content delivery and large routing tables in a fixed access solution with a wide range of uplink choices for
deployment flexibility.
Flexible NetFlow
• Cisco IOS Software FNF is the next generation in flow visibility technology. It enables optimization of the network
infrastructure, reduces operating costs, and improves capacity planning and security incident detection with
increased flexibility and scalability. The Catalyst 9300 Series is capable of up to 64,000 flow entries on 48-port,
24-port, and 12-port models and up to 128,000 flow entries on Multigigabit models.
Application visibility and control
• Next-Generation Network-Based Application Recognition (NBAR2) enables advanced application classification
techniques, up to 1400 predefined and well-known application signatures, and up to 150 encrypted applications
on the Cisco Catalyst 9000 switches. Some of the most popular applications included are Skype, Office 365,
Microsoft Lync, Webex, and Facebook, among many others that are predefined and easy to configure. NBAR2
provides the network administrator with an important tool to identify, control, and monitor end-user application
usage while helping ensure a quality user experience and securing the network from malicious attacks. NBAR2
leverages FNF to report application performance and activities within the network to any supported NetFlow
collector, such as Cisco Prime®, Cisco Secure Network Analytics, or any compliant third-party tool.
