Part 1: SMB Network Design Basics

Core-Distribution-Access Layer Concept

Most SMB networks follow a three-layer hierarchy: Core, Distribution, and Access layers:

• Core Layer: Handles high-speed aggregation and routing across floors or departments.
• Distribution Layer: Connects Core and Access, enforcing policies, VLAN segmentation, and security.
• Access Layer: Provides connectivity to endpoints such as PCs, IP phones, APs, and security cameras.

A clear hierarchical design ensures stability, simplified troubleshooting, and smooth future expansion.

L2 vs L3 Switch Comparison

Tip: Use L3 switches at the Core for routing efficiency; L2 switches suffice at Access to optimize costs. See Layer2 vs Layer3 comparison for more.

Part 2: PoE and Stackable Switch Considerations

PoE Deployment Tips

Power over Ethernet (PoE) simplifies powering wireless APs, IP phones, and cameras through a single Ethernet cable. Key considerations:

• Ensure total PoE budget covers all devices
• Choose switches compatible with 802.3af/at/bt standards
• Verify the number of ports meets current and future needs

More on PoE standards and differences and choosing the right PoE switch.

Stackable Switch Design

Stackable switches allow multiple units to operate as a single logical system:

• Scalability: Easily add switches as the network grows
• Simplified Management: Manage the stack as a single device
• High Availability: StackPower and Cross-Stack EtherChannel ensure redundancy
• Cisco StackWise: Catalyst 9300 supports StackWise-1T/480/320, stacking up to 8 switches

Part 4: Sample Deployment Topologies

Small Office (20–50 Users)

• Core: 9300X
• Distribution: 2 x 9300 stacked
• Access: 9200 PoE for APs & IP phones

Multi-Floor Office (100–200 Users)

• Core: 2 x 9500 stacked
• Distribution: 2 x 9300 per floor stacked
• Access: 9200 PoE+ stacked for multiple APs and phones

Part 5: Procurement and Support Guidance

• Fast Quotes and Global Inventory: Router-switch enables users to quickly check stock and obtain quotes, minimizing delays.
• Genuine Products and Technical Guidance: All devices are genuine, with professional network topology and design support.
• Multi-Brand One-Stop Procurement: Simplifies supply chain management with mixed-brand options.
• Flexible Payment and Global Delivery: Multiple payment options and worldwide delivery ensure project continuity across regions.

Integrating these considerations allows technical decisions and procurement actions to align naturally, making deployments smoother and more predictable.

Part 6: FAQ

Q1: What are the key elements in SMB network design?

Core-Distribution-Access layers, L2/L3 choice, PoE support, stackability, and budget considerations.

Q2: How to choose between L2 and L3 switches?
