Explain the function and contents of network documentation, including router, switch, and end-user documentation, as well as network topology diagrams.

Explain the function and contents of network documentation, including router, switch, and end-user documentation, as well as network topology diagrams.

Router documentation:

• The router documentation should include the router names, model designation, location in the enterprise (building, floor, room, rack, panel), configured interfaces, data link layer addresses, network layer addresses, routing protocols configured, and any additional important information about the device.

Switch documentation:

• The switch documentation should include the switch names, model designation, location in the enterprise (building, floor, room, rack, panel), management IP address, port names and status, speed, duplex, STP state, PortFast setting, trunk status, Layer 2 or Layer 3 EtherChannel, VLAN IDs, and any additional important information about the device.

End-user documentation:

• The end-user documentation should include the server names and functions, operating system version, IP address, gateways, DNS server, network application, and any additional important information about the device.

Topology diagrams should be available in a physical and logical variation.

Physical network topology diagram:

• A graphical representation that identifies the physical location of the networking device.
• Also details the types of cabling between them and the cable identification numbers.

Logical network topology diagram:

• A graphical representation that uses symbols to identify each network device and how it is interconnected.
• Also details the logical architecture, including interface types and numbers, IP addresses, subnet masks, routing protocols, autonomous system domains, and any additional important information, such as DLCI numbers and Layer 2 protocol.
