2.1.1 Enterprise Network Documentation
▪ Network infrastructure diagrams
- Physical topology map - Logical topology map
- Describe the Point-of-Presence for service delivery. - Identify security considerations and equipment at the
enterprise edge.
▪ Identify router and switch hardware characteristics and use router CLI configuration and verification commands.
▪ Documentation of the cable plan and testing are critical to network operations.
- All cables should be labeled at both ends, using a standard convention that indicates source and destination.
▪ Switches need to be positioned near patch panels and close to where the cabling is gathered into cable trays.

2.1.2 Network Operations Center (NOC)
▪ Equipment in the enterprise NOC is usually mounted in racks.
- All cable runs should be documented on the physical network topology diagram.
- All cable runs, both copper and fiber, should be tested end-toend by sending a signal down the cable and measuring loss.
▪ Blueprints can be marked up, or redlined, to show the changes.
▪ As-built diagram documents changes from original plans.
