What You Will Learn

1. Initial Configuration and Password Recovery

• Perform initial setup on Cisco routers and switches.

• Configure hostnames, passwords, and IP addresses.

• Recover lost passwords using password recovery techniques.

2. Switching Technologies

• VLANs: Create and manage VLANs, configure trunk ports, and implement inter-VLAN routing.

• STP (Spanning Tree Protocol): Understand and configure STP to prevent loops in the network.

• VTP (VLAN Trunking Protocol): Learn how to synchronize VLAN information across switches.

• EtherChannel: Configure link aggregation for increased bandwidth and redundancy.

3. Switch Security
