Hallittava L2/L3 Gigabit Ethernet -kytkin Cisco C9300L-24P-4X-E

The Cisco C9300L-24P-4X-E is a managed L2/L3 Gigabit Ethernet switch from the Cisco Catalyst 9300 Series, designed for enterprise access and aggregation. It provides 24 Gigabit RJ-45 ports (10/100/1000 Mbps), one USB 2.0 port and supports full-duplex operation, a 32,000-entry MAC address table and a range of IEEE networking standards for interoperability. The switch is optimized for secure, high-density deployments and integrates with Cisco architectures such as Software-Defined Access (SD-Access), StackWise stacking and StackPower for resilient power and stacking performance.

Advantages

The C9300L-24P-4X-E delivers high-density Gigabit connectivity with PoE capabilities and enterprise-class L2/L3 feature support. It offers StackWise stacking bandwidth and StackPower-compatible power resiliency, a modern x86-based platform with increased memory for programmability and support for Cisco IOS XE features including advanced security and IoT convergence. Compliance with multiple IEEE standards ensures wide interoperability in mixed-vendor networks.

Suitable for

• Access-layer switching in enterprise and campus networks
• PoE deployments for IP phones, wireless access points and cameras
• Racked network closets and distribution switches
• Environments requiring integration with Cisco SD-Access and StackWise stacks

How to use

Mount the switch in a standard 19-inch rack and connect power according to site guidelines. Use the Gigabit RJ-45 ports to connect endpoints, access points and uplinks; configure VLANs, L2/L3 routing, PoE settings and security policies through the Cisco IOS XE command-line interface or management platform. For stacked deployments, connect StackWise stack cables and verify stack master election; enable StackPower as required for redundant power sharing. Apply firmware and configuration templates following Cisco best practices.

Recommendations

For typical enterprise access deployments, enable appropriate PoE budgets per port for connected devices, configure port security and 802.1X authentication for user access control, and integrate the switch into a StackWise stack to benefit from sub-50 ms failover and centralized management.
