Viktor Barzin be80ef23bb ADR-0017 rev 3: single switch — PE replaces the SG105E, CCTV rides a VLAN-30 trunk on the LAN1 cable
Viktor prefers not running two switches, so the TL-SG105PE takes over
all rack duties (apartment uplink, 4G, UPS, camera PoE) and the CCTV
segment moves onto a managed tagged trunk over the existing LAN1 cable:
pfSense net3 re-pointed from vmbr2 to vmbr0 tag=30 (applied live; same
MAC so vtnet3/dCCTV survived untouched). This is safe where the original
802.1Q rejection was not, because the managed switch is the only device
on eno1 and polices VLAN-30 membership. eno2/vmbr2 kept dormant as the
documented fallback. Old SG105E retires to cold spare; PE inherits
192.168.1.6. Glossary Segment term updated (all three segments are now
bridge-tags feeding untagged pfSense vNICs).
