IGMP Snooping
Configure IGMP Snooping Settings
IGMP Snooping
The IGMP snooping feature filters multicast traffic sent across your switch only to the
multicast hosts and servers. This will prevent multicast traffic from flooding all ports of
the switch in order to prevent unnecessary switch processing and optimize switch
traffic. The switch supports IGMP 1/2/3 snooping.
1. Log into your switch management page (see “ Access your switch management page ”
on page 6).
2. Click on IGMP Snooping.
3. Review the settings. Click Apply to save the settings.

Block Unknown Multicast – Enabling this option will prevent or drop multicast
traffic from an unknown multicast source address.

Enable IGMP Snooping – Check this option to enable IGMP snooping.

IGMP Static Router Port – IGMP snooping will automatically learn the ports of
the multicast server, you may statically set the port where the multicast server
is connected or linked from another switch.
The table will display the discovered multicast group address, multicast
server/router port, and VLAN ID.
PoE Configuration
The main advantage of PoE is that it can make installing a network easier. The selection
of a location for a network device is often limited by whether there is a power source
nearby. This constraint limits equipment placement or requires the added time and cost
of having additional electrical sources installed. However, with PoE, you can install PoE
compatible devices wherever they are needed without having to worry about whether
there is power source nearby.
Power Sourcing Equipment (PSE)
A device that provides PoE to other network devices is referred to as
power sourcing equipment (PSE). The Gigabit Web Smart PoE+ Switch is a PSE
device which provides DC power to the network cable and functions as a central power
source for other network devices.
Powered Device (PD)
A device that receives power from a PSE device is called a powered
device (PD). Examples include wireless access points, IP phones, webcams, and even
other Ethernet switches.
PD Classes PDs are grouped into five classes. The classes are based on the amount of
power that PDs require. The Gigabit Web Smart PoE+ Switch supports all five classes.
