The Cisco Catalyst 9200L-24P-4G-A is a 24-port managed Layer 2/Layer 3 enterprise Ethernet switch from Cisco’s Catalyst 9200L Series, designed primarily for branch, campus access layer, or small-to-medium business networks. It offers Power over Ethernet Plus (PoE+) — useful for powering devices like VoIP phones, wireless access points, and security cameras — along with modern software features through Cisco’s IOS XE and Network Advantage licensing.

Key Specifications

Ports & Connectivity

• 24 × 10/100/1000 Mbps PoE+ ports — all capable of supplying IEEE 802.3at PoE+ power.

• 4 × 1 Gbps fixed uplink ports (SFP) for fiber or other uplink connections.

• PoE power budget: typically ~370 W with one PSU (enough for most APs/phones), upgradable with a second PSU for up to ~740 W total.

Performance & Architecture

• Switching capacity: ~56 Gbps total.

• Forwarding rate: ~83.3 Mpps.

• Stacking: Supports Cisco stacking via StackWise (up to ~80 Gbps).

• Memory: ~2 GB DRAM, ~4 GB flash.

Features

Software & Features

• Cisco IOS XE OS: modern enterprise OS with programmability, security, and automation.

• Network Advantage license (-A suffix): enables advanced Layer 3 routing features (OSPF, EIGRP, RIP, VRRP), policy-based routing, Flexible NetFlow, enhanced telemetry, and more.

• Security: MACsec encryption, Trustworthy Systems, ACLs, DHCP snooping, etc.

Physical & Environmental

• Rack-mountable 1U form factor with redundant fans and field-replaceable parts.

• Typical enterprise environmental ratings (operating temperature up to ~45 °C).

Performance & Scaling

• Cisco UADP 2.0 Mini architecture with integrated CPU for optimized scale and performance efficiency.

• Stacking support (e.g., with StackWise backplane) allows multiple switches to operate as a single logical unit, improving scalability and manageability.

• Layer 2 and Layer 3 performance — supports routing for distributed and segmented networks.

Advanced Software & Intelligence

• Cisco IOS XE with Network Advantage license (-A) — enables advanced Layer 3 routing such as OSPF, EIGRP and more.

• Support for Cisco SD-Access — simplifies operations and automates policy-based configurations for consistency across campus or branch environments.

• Plug-and-Play (PnP) support for easier rollout and onboarding of new network devices.

Security & Monitoring

• AES-128 MACsec encryption for secure data links between switches and endpoints.

• Policy-based segmentation and trust anchor features provide strong network access controls.

• Full Flexible NetFlow (FNF) for deep traffic visibility and enhanced monitoring.

Deployability & Management

• Scalable VLAN and segmentation support for flexible traffic separation in enterprise environments.

• Support for a broad set of protocols and automation tools including RESTCONF/NETCONF and telemetry (depending on IOS XE features).

• Rack-mountable 1U form factor for standard enterprise infrastructure deployments.

Summary of What Makes It Stand Out

• Full PoE+ support across all 24 ports with scalable power budget.

• Enterprise-grade switching and routing features due to the Network Advantage license.

• Advanced security and monitoring capabilities fit for modern network access layers.

• Stackability and automation readiness for growth and simplified management.

What the Model Code Means

• C9200L: Cisco Catalyst 9200L Series (lightweight, cost-efficient variant of the 9200 platform).

• 24P: 24 PoE+ ports.

• 4G: 4 × 1 Gb uplinks.

• A (“Network Advantage”): Enhanced software license with more advanced routing and features than the Essentials tier.
