Cisco BCMSN 640-811

1. Multilayer Switching: Understanding the concepts and configurations related to multilayer switching, including VLANs, VLAN trunking, inter-VLAN routing, and Layer 3 switching.

2. Spanning Tree Protocol (STP): Knowledge of STP operation, including IEEE 802.1D, IEEE 802.1w (Rapid Spanning Tree Protocol), and IEEE 802.1s (Multiple Spanning Tree Protocol).

3. Virtual LANs (VLANs): Configuration and management of VLANs, including VLAN membership, VLAN trunking, VLAN tagging, and VLAN routing.

4. EtherChannel: Configuration and implementation of EtherChannel to provide higher bandwidth and redundancy by aggregating multiple physical links into a single logical link.

5. IP Routing: Understanding of IP routing concepts and protocols, including static routing, dynamic routing (such as OSPF and EIGRP), and route redistribution.

6. Network Security: Knowledge of network security features and technologies, including access control lists (ACLs), port security, and private VLANs.

Before learning Cisco BCMSN 640-811, it's recommended to have a foundational understanding of networking concepts and technologies. Here are some skills that can be beneficial:

1. Basic Networking Knowledge: Familiarity with networking fundamentals such as OSI model, TCP/IP protocol suite, IP addressing, subnetting, and Ethernet LAN technologies.

2. CCNA-level Knowledge: Having completed Cisco's CCNA (Cisco Certified Network Associate) certification or possessing equivalent knowledge would provide a solid foundation. CCNA covers topics like network fundamentals, LAN switching technologies, routing technologies, WAN technologies, infrastructure services, and infrastructure maintenance.

3. Switching Concepts: Understanding of switching concepts including VLANs (Virtual LANs), STP (Spanning Tree Protocol), EtherChannel, VLAN trunking, VLAN routing, and Layer 3 switching.

4. Routing Protocols: Basic knowledge of dynamic routing protocols like OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol).

5. Network Security Fundamentals: Understanding of network security principles and technologies such as access control lists (ACLs), port security, and basic authentication mechanisms.
