8.1.9 - Logical Network Diagrams

Flashcards covering key concepts and definitions related to logical network diagrams, including layers of networking, schematic representation, and iconography.

PHY (Physical Layer)

Deals with asset IDs, cable links, and wall/patch panel/switch port IDs.

Data Link (Layer 2)

Shows interconnections with asset IDs, interface IDs, link-layer protocol, and bandwidth.

Logical (IP/Layer 3)

Involves IP addresses, static IP assignments, firewalls, network ID, netmask, VLAN ID, and DHCP scopes.

Schematic Diagram

A simplified representation of a system showing equipment placement without capturing exact positions.

Color-Coding in Network Diagrams

A method to represent different cable types in diagrams, requiring a legend for clarity.

Line Thickness in Diagrams

Can be used to represent bandwidth in the Data Link layer.

Cisco Icons

Standard icons created by Cisco used in network schematic diagrams.

Performance Baselines

Configuration information including CPU, memory, storage, and network utilization.

Common Network Devices Icons

Includes symbols for hub, access point, switch, router, firewall, etc., used in network diagrams.
