Tips #11 - Shorthand notation for network diagrams

The following are some example rules for diagram shorthand notation.  This was developed to be able to not only indicate where the connections are, but to identify the ports on each end.  Makes it easy to put a wiring list together.

  • General Format: {port_from}[What_flow_contains]{port_to}
  • Port designation: {device-port}
    • {ONT} for Verizon ONT
    • {SW1-5} for Switch#1, port 5
    • {RT3-2} for Router#3, port 2
    • {RT3-W} for Router#3, wan port
    • {RPi05-D1} for Raspberry Pi #5, dongle on usb port 1
    • {RPi05-E} for Raspberry Pi #5, ethernet port
    • {PP1-15} for patch panel #1, port 15
  • Flow designation: [non_tagged_vlan/Ttrunk_vlan_list]
    • [32] for non-tagged vlan 32
    • [T4,6,8] for tagged vlans 4, 6, and 8
    • [12/T14,70] for non-tagged vlan 12 with tagged vlans 14 and 70
    • [Trunk] for generic <defined elsewhere> trunk with tagged vlans; shorthand
