Introduction

LANCOM “firewalls” overview (LCOS-FX, LCOS, LCOS-SX)

Product families you’ll meet

• LCOS-FX = Unified Firewalls (R&S® UF-series). Admin via web UI on TCP 3438 (HTTPS). Defaults below.
• LCOS (routers/gateways) = classic LANCOM devices with the tree-style CLI (cd, set, add, del). Often used as edge firewall too.

• LCOS-SX (switches) = where you’ll do VLAN tagging/trunks, view MAC tables, etc., via Cisco-like CLI (switchport …, show vlan …).
