Product Description
The Cisco CBS350‑48T‑4X‑CN is a high‑performance 48‑port managed Gigabit Ethernet switch in Cisco’s Business 350 Series tailored for modern business networks that demand high‑density connectivity, advanced security, and scalable uplinks. It combines robust Layer 2 switching features with basic Layer 3 routing capabilities, enabling VLAN segmentation and inter‑VLAN communication across medium to large networks.
Model Type: Managed Gigabit Ethernet Switch (Layer 2 + Basic Layer 3)
Category: Cisco Business 350 Series 48‑Port Managed Switch with 10 Gbps Uplinks
Key Features
• 48 × 10/100/1000 Mbps Gigabit RJ‑45 Ports — Provides high‑density copper connectivity for desktops, servers, APs, and other network devices.
• 4 × 10 Gbps SFP+ Uplinks — High‑speed fiber uplinks support backbone aggregation and connections to core switches or data center links, enabling scalable growth.
• Advanced Switching & Routing — Combines advanced Layer 2 features with static IPv4/IPv6 routing, support for up to 990 static routes, Policy‑Based Routing (PBR), and RIP v2 for inter‑VLAN routing and basic Layer 3 traffic handling.
• Robust Security & Traffic Control — Includes IEEE 802.1X port access control, RADIUS/TACACS+, DHCP Snooping, IP Source Guard, Dynamic ARP Inspection, IPv6 First Hop Security, and ACLs for secure network segmentation and protection.
• True Hardware Stacking — Up to 4 switches can be stacked into a single managed system with fast failover and centralized management IP.
• Comprehensive VLAN Support — Supports up to 4,094 VLANs with 802.1Q tagging and multiple spanning tree protocols (PVST+, RPVST+, MSTP).
• Quality of Service (QoS) — Eight hardware queues with support for strict priority and Weighted Round Robin (WRR) scheduling for prioritizing voice, video, and other critical traffic.
• Flexible Management — Manage via Cisco Business Dashboard, web UI, CLI, SNMP (v1/v2c/v3), RMON, SSH, and HTTPS; also supports Cisco Network Plug and Play (PnP).
• Energy Efficient Design — Compliant with IEEE 802.3az Energy Efficient Ethernet to reduce power consumption during idle periods.
