Launched as Cisco’s first “Smart Switch” in the Catalyst 9000 family, the Cisco Catalyst 9350 is designed for modern enterprise campuses powering AI, IoT, and high-density Wi-Fi 7 access. It delivers up to 51.2 Tbps switching architecture, latency under 5 µs, and 100 G hardware-based IPsec encryption for secure campus access.
Aligned with Al fuzail’s mission to deliver secure, scalable, and manageable LAN infrastructure, the 9350 sets the standard for future-proof networking.
Architecture & Core Components
Built on Cisco’s UADP 2.0sec ASIC, the 9350 offers:
| Component | Specification |
| Stacking | StackWise-1.6T (1.6 Tbps, up to 8 switches) |
| Power | Up to 48× 90 W UPOE+ ports, StackPower+ for power pooling |
| Throughput | 1,760 Gbps standalone; 14 Tbps in stack at 3.8 Bpps |
| Encryption | Hardware IPsec up to 100 G AES-256; MACsec for link-level encryption |
| Software | Runs Cisco IOS XE with programmability via RESTCONF, gNMI, and containerized app hosting (e.g., ASAc firewall) |
These capabilities make the Cisco Catalyst 9350 a resilient, high-performance building block for mission-critical campus networks.
How Traffic Moves (Data Flow Insights)
Data from endpoints (wired, Wi-Fi 6/7, IoT, VoIP) enters via access ports, is classified and forwarded using QoS and ACLs, and exits through distribution/core layered routing. In campus stacks, StackWise-1.6T ensures hitless failover and unified connectivity.
Telemetry integration via Flexible NetFlow (up to 128k flows) enables real-time analytics tied into DNAC, ThousandEyes, and Stealthwatch.
Deployment Use-Cases & Configuration Models
- Standalone Access Switch: Ideal for small-to-medium branch offices.
- Stacked Campus Access: Up to 8 switches stacked as one logical unit.
- Edge & IoT Access Fabric: Use software-defined access (SD-Access) with segmentation and identity-based policies.
- Meraki-Managed Variant: Cisco provides Meraki dashboard integration on the same hardware for cloud-controlled management.
Recommended Deployment Steps
- Pre-deployment survey: RF planning, port requirement, PoE budget
- Staging: Pre-configure VLANs, QoS, stacking priority
- Infra build: Fiber and copper uplinks, power redundancy design
- Validation: Stack failover, MACsec encryption tests, route convergence
- Production handover: Continuous telemetry into Catalyst Center or Meraki dashboard
Benefits For Enterprise Network Modernization
Asserted real-world advantages include:
- Ultra-secure campus edge: AES-256 MACsec and 100 G IPsec protect both wired and inter-site traffic
- Resilient stacking: StackWise-1.6T with StackPower+ offers greater uptime (NSF/SSO under 50 ms failover)
- Scalable PoE+: Supports high port-density UPOE applications like Wi-Fi access points, keyboards, lighting, and sensors
- Cloud and automation ready: IOS XE offers model-driven programmability and built-in container support for apps like ASAc firewall
- Operational intelligence: Integrated ThousandEyes and NetFlow analytics aids troubleshooting beyond your campus perimeter
In trials by service providers, deploying C9350 stacks reduced VLAN convergence failures by 70% and improved encrypted IoT device onboarding times by 40%.
Deployment Guide for 2025
Planning & Site Survey
- Map required stacking bandwidth and PoE budget
- Plan for multigigabit access uplinks (2.5G/5G/10G)
- Identify roles: edge, distribution or IoT fallout
Configuration Essentials
- Enable MACsec on uplinks for campus segments
- Use Cross-stack EtherChannel for resilient uplinks
- Configure NetFlow Export to SIEM or ThousandEyes endpoints
- Deploy ASAc container only on C9350X if firewall consolidation is required
Optimization Checklist
- Validate StackPower+ ring topology
- Test stack rollback recovery for switch replacement
- Enable Flexible NetFlow templates for monitoring up to 128K entries
- Enforce secure keychain and TACACS credential management for access control
