Network Backbone & Access
Production switching, addressing, and remote-access path used by all tile and backend services.
Deployed Facts
Section titled “Deployed Facts”- Four color-coded switches are documented:
white,blue,red,yellow. - Switch docs define a Techtile VLAN and inter-switch links via channel-group ports.
- Port assignments for midspans, DAQ, RAID, server, and time-provider are documented in switchport tables.
- Patch panel to midspan port mappings exist for tile identifiers (
A1..G20). - VPN gateway infrastructure runs on
VEP1405usingVyOS.
Addressing Notes
Section titled “Addressing Notes”Switch_overview.pdfdocuments192.108.0.0/24as Techtile VLAN scope.IP address overview.docxcontains legacy/expanded ranges (/22) and a detailed asset table.- The extracted tables below preserve source values from operational files.
