Cisco-Catalyst WS-C3850-24S-E
The Cisco Catalyst WS-C3850-24S-E is a 24-port Gigabit Ethernet Layer 3 managed fiber switch designed for enterprise campus, aggregation, distribution, and fiber-based access networks. It provides 24 × 1G SFP interfaces, advanced Layer 2/Layer 3 switching, StackWise-480, enterprise security, QoS, and Cisco IOS XE with the IP Services feature set.
Description
The Cisco Catalyst WS-C3850-24S-E is part of the Cisco Catalyst 3850 Series, an enterprise-class switching platform designed to provide scalable, secure, and reliable network connectivity for campus and business environments.
The switch provides 24 Gigabit Ethernet SFP ports, making it particularly well suited for fiber-based network infrastructure. These interfaces can connect to aggregation and distribution switches, servers, remote buildings, backbone links, and other fiber-enabled network equipment.
The SFP interfaces provide flexibility in selecting compatible Cisco transceivers based on the required fiber type, transmission distance, and network topology. This makes the WS-C3850-24S-E appropriate for environments where copper connectivity is not required at the access layer.
The switch operates on Cisco IOS XE, providing enterprise Layer 2 and Layer 3 functionality. Supported technologies include VLANs, trunking, STP/RSTP/MST, EtherChannel, IPv4/IPv6 routing, OSPF, EIGRP, VRF-Lite, multicast, QoS, and security controls.
The Catalyst 3850 platform incorporates StackWise-480, enabling compatible switches to be connected and managed as a single logical switching system. StackWise-480 provides up to 480 Gbps of stack bandwidth, helping organizations build scalable and resilient switching infrastructures.
The -E designation identifies the IP Services software feature set, providing advanced enterprise Layer 3 routing capabilities compared with IP Base configurations.
The WS-C3850-24S-E uses a 1U rack-mount chassis, allowing it to be installed efficiently in enterprise network cabinets, server rooms, and data-center environments.
