Cisco Catalyst 9300 Series Switches

The Cisco Catalyst 9300 Series switches are Cisco’s premier stackable enterprise access switches, engineered for a hybrid world where the workplace is anywhere, devices are diverse, and applications are distributed across clouds and data centers. As the cornerstone of the Catalyst 9000 family, these switches deliver secure, high-performance access and are purpose-built for scalable, resilient network architectures.

Powering the Future of Enterprise Connectivity

Designed to transform enterprise networking, the Catalyst 9300 Series—including the advanced Catalyst 9300X models—brings unprecedented flexibility and innovation. Whether deployed on-premises, virtually, or via the cloud, these switches empower IT teams with operational agility, security, and advanced network intelligence.

Key Innovations and Industry Firsts

• Unmatched Stacking Bandwidth: Up to 1 Tbps with StackWise-1T, the industry’s highest-density stacking solution.
• Flexible Uplink Options: Support for 100G, 40G, 25G, 10G, 1G, and Multigigabit modular uplinks.
• Mixed Stacking: Backward-compatible stacking across Catalyst 9300, 9300X fiber, and Multigigabit models.
• Unrivaled Multigigabit Density: Up to 48 mGig ports per switch, and 448 mGig ports in an 8-member stack.
• Leading 90W UPOE+ Support: Deliver up to 384 ports of 90W UPOE+ across a stack.
• Hardware-based 100G IPsec: Secure, high-speed edge connectivity with line-rate IPsec encryption.
• Application Hosting: Run high-performance Cisco apps natively with expanded RAM, storage, and compute.
• Secure Tunnel Connectivity: Native AES-256 IPsec tunneling for site-to-site and cloud service integration.
• ThousandEyes & ASAc Integration: Enable full path visibility and embedded firewall functions directly on the switch.
• Cloud Management with Meraki Dashboard: Optional cloud-based visibility, configuration, and troubleshooting.
• Investment Protection: Redundant fans, power supplies, stack cables and modules are fully backward-compatible.

Engineered for a Software-Defined Future

As a foundational element of Cisco’s Software-Defined Access (SD-Access) architecture, Catalyst 9300 switches support:

• Automated policy-based operations from edge to cloud
• Simplified segmentation and virtualization
• Unified wired and wireless network management
• Group-based policies and context-aware analytics

With Cisco DNA and Meraki software subscriptions, customers benefit from:

• Flexible, value-based software licensing
• Ongoing access to software updates and innovations
• Cross-platform management and visibility through Cisco DNA Center or Meraki Dashboard

Advanced Platform Capabilities

• Built on the Cisco UADP 2.0 and 2.0sec ASICs for programmable Layer 2/3 forwarding, ACLs, and QoS
• x86 CPU architecture, up to 16GB RAM, and up to 240GB external SSD for container-based services
• PoE, PoE+, UPOE and UPOE+ support for high power endpoint devices
• Cisco StackPower for dynamic power sharing and redundancy
• Line-rate Flexible NetFlow, IPv6 support, dual-stack forwarding, and Precision Time Protocol (PTP)
• Encrypted Traffic Analytics (ETA) for malware detection in encrypted traffic
• MACsec 256-bit encryption across all models
• Secure Boot and SUDI for hardware and software integrity validation

Simplified Deployment and Operations

• Plug and Play (PnP) support for secure, zero-touch provisioning
• Fully programmable OS with Cisco IOS XE, supporting YANG models, Python scripting, RESTCONF, and streaming telemetry
• Consistent policy and management across all deployment models—on-prem, virtual, and cloud
