IntrisingTM WDG0204S-1ac

IntrisingTM WDG0204S-1ac is a high performance wireless router build-in L2+ 4x GE ports ethernet switch w/ 4 PoE 802.3af/at per port 30W which provides L2+ wire speed and management functions for network deployment. In the redundancy, It delivers ITU G.8032 ring recovery less than 50ms, further less than 20ms** in the enhance mode. It can help optimization network traffic by comprehensive QoS and load balancing. Security functions including L2/L3 ingress and egress ACL, port based DHCP server, MAC based DHCP server, also include option 82/66* for DHCP relay. In order optimization AV traffic, it provide IGMP v1/v2/v3/ and router port support, which are important features required in AV network. The network discovery support LLDP and CDP(Cisco Discovery Protocol)** that help scan and show whole network topology. That support four mechanism for load balancing include fixed, failover, priority and round robin. It can help to fully used WAN resource. VRRP can increase availability and reliability via automatic choice master default gateway in network topology. If the master is broken, slaves will be wake up and replace it quickly. WI-FI can work as access point (AP) or station (client) mode, both support dual-band 2.4G and 5G, providing a way to easy and flexible to build up a wireless environment.

Dual gigabit WAN ports and load balancing with four mechanisms

WDG0204S-1ac provides two gigabit ethernet WAN port that work concurrent. Also support four algorithm to scheduling WAN port traffic, include fixed, failover, priority and round robin that help to appropriate used WAN bandwidth.

2.4G & 5G Dual Band WI-Fi

Support 801.11a/b/g/n/ac WI-FI, maximum three antenna with 3x3 MIMO, bandwidth up to 1300 Mbps.


VRRP let more availability and reliability in the network. VRRP can automatic choice one router as default gateway(master) and let others as standby(slave).

PoE at/af ports with advanced PoE management

Compliant with 802.3af/at standard, the WDG0204S-1ac is able to feed each PoE port up to 30 Watt, 250W totally. Also supports advanced PoE management functions, such as PD detection, scheduling and health tracking**. PoE detection can detect if the connected PD status such as enabled/disabled, voltage, current, watt and temperature; scheduling is to allow pre-set power feeding schedule upon routine time table; health tracking can detect PD is alive or not, if PD is dead, will restart it.

QoS and DiffServ

WDG0204S-1ac supports 802.1p CoS(Class of service) QoS and DiffServ that greatly enhance the bandwidth management in a network.

IGMPv1/v3/v3 and Router port

IGMPv1/v2/v3 is an important feature in the AV network. It bring a lot of benefit such as management multicast traffic, save switch bandwidth.

G.8032 ring and 8/16* MSTI MSTP

ITU G.8032 ring which can be self-healed in less than 50ms for single ring topology protection. It also supports various ring topologies that include double ring, multi-chain, basic ring and multiple-VLAN ring**. It supports MSTP with up to 8 MSTI that allows each spanning tree for each VLAN for redundant links and backward compatible STP and RSTP.

Port/MAC based DHCP server, option 82** DHCP Relay and IPv6 DHCP server**

MAC based DHCP server can assign dedicated IP address by by client’s MAC Address. Option 82 can assign IP address by port for multiple switches with single DHCP option 82 server.

Event log and Event Action

WDG0204S-1ac has many useful log for network trouble shutting. Once out of the situation sending SMS**, e-mail, SNMP trap or syslog to the manager immediately.

Dual power DC input

WDG0204S-1ac supports dual DC power supplies DC 9V to 56V input to increase the network reliability.
