+
+  3. **Advanced Layer 2 and Layer 3 Features**: The switch provides comprehensive Layer 2 and Layer 3 switching
+     and routing features, including support for VLANs, VXLAN, Routing Information Protocol (RIP), Open
+     Shortest Path First (OSPF), Border Gateway Protocol (BGP), and Enhanced Interior Gateway Routing
+     Protocol (EIGRP). VXLAN and EVPN: With Virtual Extensible LAN (VXLAN) and Ethernet VPN (EVPN)
+     capabilities, the switch allows for scalable multi-tenant network segmentation, enabling organizations
+     to create isolated virtual networks across Layer 3 domains. Advanced Multicast Capabilities: It
+     includes support for Protocol Independent Multicast (PIM), Internet Group Management Protocol (IGMP),
+     and Multicast Listener Discovery (MLD) for efficient handling of multicast traffic.
+
+  4. **Programmability and Automation**: The N9K-C93108TC-FX3P can operate in Cisco NX-OS mode for traditional
+     environments or in Cisco Application Centric Infrastructure (ACI) mode for SDN and policy-driven
+     networking, providing flexibility in deployment. The switch supports RESTful APIs, Python scripting,
+     and Linux-based programmability, allowing network operators to automate and streamline network
+     management tasks. Real-time telemetry provides deep visibility into network traffic and device health,
+     enabling proactive monitoring and troubleshooting. This feature can be integrated with Cisco Nexus
+     Dashboard Insights or third-party analytics tools.
+
+  5. **Power over Ethernet (PoE) and PoE+ Support**: The N9K-C93108TC-FX3P supports up to 60W of Power over
+     Ethernet (PoE) on 36 ports, providing enough power for devices such as IP phones, wireless access
+     points, and IoT devices. The switch complies with the IEEE 802.3bt standard, allowing it to provide
+     PoE++ capabilities, which are essential for high-power devices.
+
+  6. **Security and Policy Management**: MACsec provides encryption on wired connections, ensuring data
+     security on critical network links and protecting against unauthorized interception. Access Control
+     Lists (ACLs) and Role-Based Access Control (RBAC): The switch includes granular ACLs and RBAC for
+     controlling access to network resources and restricting user actions based on roles, enhancing
+     overall security. The switch provides Control Plane Policing (CoPP) and Dynamic ARP Inspection
+     (DAI), which protect it from malicious attacks and prevent disruptions to network traffic.
+
+  7. **Energy Efficiency and High Availability**: The switch includes front-to-back or back-to-front airflow
+     options, along with redundant power supply support, enabling it to fit into a variety of data center
+     cooling configurations. It also has hot-swappable fans and power supplies for minimal service
+     interruption. Cisco EnergyWise: EnergyWise technology optimizes energy consumption, reducing the
+     overall energy footprint and operational costs.
+
+  8. **Quality of Service (QoS) and Application Prioritization**: The switch includes features like Weighted
+     Random Early Detection (WRED) and priority flow control, allowing administrators to prioritize
+     critical application traffic, ensure smooth performance for latency-sensitive applications, and
+     reduce congestion. The switch supports eight egress queues per port, enabling granular traffic
+     management for different classes of service, which helps ensure consistent performance for high-priority
+     applications.
+
+  9. **Spine-Leaf Architecture Compatibility**: The N9K-C93108TC-FX3P is well-suited for deployment as a
+     leaf switch in a leaf-spine architecture, enabling easy scalability and predictable performance.
+     It allows organizations to scale their network in a modular fashion by adding more leaf switches
+     as required, without requiring changes in the spine layer.
+
+  10. **Support for Cisco Intelligent Traffic Director (ITD)**: Cisco Intelligent Traffic Director (ITD)
+      provides efficient traffic distribution across multiple servers, reducing the need for a dedicated
+      load balancer and maximizing server utilization. ITD is particularly useful in clustered application
+      environments, such as data analytics or web hosting, where traffic needs to be evenly distributed
+      across multiple servers.
+
