The DrayTek VigorSwitch P2542x The VigorSwitch P2542x is a Layer 2+ managed switch with 48 × Gigabit PoE/PoE+ ports and 6 × 10G SFP+ fibre uplinks. Its 400W PoE budget supports powering a full range of connected devices, while dual AC and DC power inputs provide deployment flexibility and redundancy. With advanced Layer 3 features such as DHCP Server and VLAN Routing, the switch enhances network efficiency and keeps LAN services running even if the router is offline, making it ideal as a core switch for SMEs and SMBs. Key Features• PoE (Power over Ethernet) – Supplies power and data over one Ethernet cable, with PoE scheduling for automated control.• 10G SFP+ – Provides high‑speed fibre uplinks for aggregation or core‑switch connectivity.• ONVIF‑Friendly – Detects ONVIF surveillance devices, displays camera topology, and supports video streaming and remote maintenance.• Wire‑Speed VLAN Routing – Routes inter‑VLAN traffic directly on the switch to offload the router.• IPv6 Ready – Supports IPv6 features including MLD Snooping, IPv6 ACL, and IPv6 DNS Resolver.• Auto Surveillance & Voice VLAN – Automatically identifies IP cameras and IP phones and applies QoS tags.• Web‑Based GUI – Provides an intuitive interface for monitoring ports and hardware status.• IP Conflict Prevention – Detects and blocks misconfigured or malicious hosts.• Multiple Admin Accounts – Supports multiple administrators with two privilege levels.• Access Control – Supports IP/MAC ACLs and 802.1x port access control with RADIUS.• Central Switch Management – Enables VLAN setup and centralised monitoring from a Vigor router.• QoS (Quality of Service) – Prioritises critical traffic using CoS, DSCP, and IP Precedence.• Energy‑Efficient Ethernet – Reduces power consumption via IEEE 802.3az compliance.• LLDP‑MED – Detects VoIP devices, simplifies VLAN assignment, and prioritises voice traffic.• Stacking – Allows multiple switches to operate as one for improved scalability and resilience. Further Details: Advanced Layer 2+ FeaturesThe switch includes a DHCP Server supporting up to eight VLANs and VLAN Routing supporting up to 512 routes. These features reduce router workload and keep LAN services operating even when the gateway is offline. Bind IP to MACAs a DHCP server, the switch can reserve IP addresses for important devices, ensuring consistent access for frequently used endpoints. Stacking — Build a Resilient & Flexible NetworkUp to four P2542x units can be stacked to form a single logical switch, enabling centralised management, unified configuration, automatic firmware synchronisation, and seamless failover. Stacking also integrates security features such as DHCP Snooping, ARP Inspection, and Port Security. ONVIF‑FriendlyThe switch detects ONVIF devices across VLANs, displays camera topology, and enables remote maintenance such as rebooting or resetting devices. It can also take periodic snapshots and send alerts when cameras stop responding, with PoE models able to power‑cycle affected ports automatically. IP Conflict Detection & PreventionThe switch monitors for IP conflicts and alerts administrators when issues arise. It can also block problematic hosts to maintain a stable network environment. Device CheckContinuously pings LAN devices and sends alerts if they stop responding. On PoE models, it can automatically power‑cycle the affected port. LAN ManagementDrayTek’s management platform enables automatic device discovery, remote provisioning, centralised monitoring, and system maintenance (such as configuration backup or remote reboot) directly from a Vigor router. Software ManagementVigorACS 3Provides provisioning, monitoring, hierarchical views, alarms, remote maintenance, and scheduled reporting.
