Docs/Switches

Our firewall/router runs pfSense, soon to be migrated to OPNsense.

All IP addressing of servers and virtual machines happens through DHCP, and can be viewed in the pfSense 'DHCP Leases' tab. (except Proxmox nodes, which don't support DHCP and require static addressing)

Otherwise, most configuration can be viewed by poking around the web interface.

Switches

WAN

Our WAN is a LAGG across two ports. The link needs LACP enabled ("Static mode" off in 1Gb Ubiquiti Switch) [1], and STP off.

IT configures their switches to automatically shut off ports if they detect STP advertisements.

Reference commands to make a Cisco switch satisfy the requirements:

(config-if)# spanning-tree bpdufilter enable
(config-if)# spanning-tree bpduguard disable

Internal VLANs
