Integrates Security Group Tags (SGTs) and hardware-based MACsec encryption to secure data in transit across the campus.

Unlike the traditional IOS 12.2(50)SG or 15.1(2)SG releases, Release 3.11.0E runs on the IOS XE architecture. While the Catalyst 4500E implementation does not utilize the full "Front Panel Access" (Fretta) Linux Container architecture found in the Catalyst 3850 or 9000 series, it represents a significant kernel modernization.

Designed for basic layer 2 access switching. It includes standard VLAN trunking, robust Quality of Service (QoS), fundamental security features (such as 802.1X and Access Control Lists), and static routing capabilities. 2. IP Base

The platform offers granular Class of Service (CoS) and Differentiated Services Code Point (DSCP) mapping. It features advanced policing, shaping, and queuing algorithms to guarantee bandwidth for critical voice and data paths.

is a solid, mature choice for a stable production environment. However, if your hardware supports it, check the Cisco Software Download page : Designed for basic layer 2 access switching

The software ensures that the control plane (routing protocols, management traffic, and system configuration) remains decoupled from the data plane (hardware-accelerated packet forwarding). If a control plane process stalls, hardware-level switching and routing continue uninterrupted. Symmetric Multiprocessing (SMP)
