- Virtual LANs (VLANs): The switch supports VLANs, which allows for segmenting a physical network into multiple logical networks. This improves the security and organization of a network.
- Link Aggregation Control Protocol (LACP): The switch supports LACP, which allows for bundling multiple physical ports into a single logical link. This increases bandwidth and provides redundancy in case of a port failure.
- Quality of Service (QoS): The switch supports QoS which allows for prioritizing different types of traffic to ensure that critical applications receive the bandwidth they need.
- Access Control Lists (ACLs): The switch supports ACLs which allow for filtering of inbound and outbound traffic based on specified criteria. This improves security by blocking unwanted traffic and allowing only authorized traffic to pass through the network.
- Multi-Protocol Label Switching (MPLS): The switch supports MPLS, which allows for efficient routing of data packets by using labels instead of traditional IP addresses and routing tables.
- Advanced Security: The switch supports various security features such as Cisco TrustSec and Cisco Identity Services Engine (ISE) for advanced network access control and security management.
- Virtual Routing and Forwarding (VRF) Lite: This feature allows for creating multiple routing instances on a single router. This improves the security and organization of a network by isolating different routing domains.
These advanced routing and switching capabilities of the WS-C3850-24T-E Cisco Catalyst 3850 series switch provide network administrators with the flexibility and control they need to optimize network performance and security. It supports advanced layer 3 routing protocols, link aggregation, Quality of service, Access control lists, Multi-Protocol Label Switching Advanced security features making it suitable for enterprise-class network deployments.
Security and Quality of Service
Security: The WS-C3850-24T-E Cisco Catalyst 3850 provides advanced security features to help protect your network from threats. Some of these features include:
- Cisco TrustSec: This feature provides identity-based security by allowing you to assign security policies to users, devices, and applications based on their identity, rather than their IP address.
- Cisco Identity Services Engine (ISE): This feature provides network access control by allowing you to authenticate users and devices before granting them access to the network.
- Advanced threat defense: The switch is equipped with advanced threat defense features such as Cisco StackWise-480 technology, which allows for high-performance stacking of up to 9 switches and provides resiliency.
Quality of Service (QoS): The WS-C3850-24T-E Cisco Catalyst 3850 also provides advanced Quality of Service (QoS) features to help ensure that critical network traffic is delivered reliably. Some of these features include:
- Per-flow traffic shaping: This feature allows you to shape traffic on a per-flow basis, which means that you can assign different priorities to different types of traffic.
- Hierarchical QoS: This feature allows you to prioritize network traffic at different layers of the OSI model, which ensures that critical traffic is delivered reliably.
- Advanced QoS: The switch provides advanced QoS features such as class-based weight fair queuing (CBWFQ), low-latency queuing (LLQ), and Weighted Random Early Detection (WRED) which helps in providing better QoS and controlling the congestion.
