CCNA 2 v7.0 Case Study - Rev B: A Comprehensive Guide

—he reclaimed control, forcing the core switch to take its rightful place at the center of the universe. 3. The Security Breach ccna-2v7.0 case study -rev b-

Option B – Layer 3 Switch (if applicable) – enable IP routing and SVI. CCNA 2 v7

• Enabling the physical interface with no shutdown.
• Creating subinterfaces (e.g., interface g0/0.10, g0/0.20, g0/0.30).
• Assigning 802.1Q VLAN IDs and IP addresses using encapsulation dot1Q vlan-id and ip address.
• The switch port connecting to the router is configured as a trunk, carrying all VLANs.

4. Common Pitfalls (Rev B)

• Forgetting to set native VLAN match on both ends of trunk.
• Using switchport access vlan on trunk ports.
• Not enabling ip routing on a multilayer switch if using SVIs.
• EtherChannel config mismatch (mode and VLANs must be identical on both switches).
• Not disabling DTP if setting trunk manually.

Do not proceed until you draw the topology from the case study document. Label all interfaces, IP networks, and VLAN IDs. This visual map is your single source of truth. Enabling the physical interface with no shutdown
