NOTE

At least one switch must be designated the querier when enabling Turbo Ring and IGMP

snooping simultaneously.

IGMP Table

EDS-508 displays the current active IGMP groups that it detected.

The information includes VID, Auto-learned Multicast Router Port, Static Multicast Router Port,

Querier Connected Port, and the IP and MAC addresses of active IGMP groups.

Add Static Multicast MAC

MOXA EtherDevice Switch can also support adding multicast groups manually if required.

Add New Static Multicast Address to the List

Setting Description Factory Default

Join Ports

Setting Description Factory Default

Using Rate Limiting

Single devices should not occupy unlimited bandwidth, especially when the device malfunctions.

The most well-know problem is the broadcast storm caused by an incorrect topology or

malfunctioning device. The EDS-508 series not only prevents broadcast storms, but can also

configure the ingress/egress rate of unicast/multicast/broadcast packets, thus helping the

administrator control fully the limited bandwidth, and prevent unpredictable faults before they

occur.
