IGMP Notes
•
It must set up 802.1Q VLAN first before enabling IGMP Snooping.
•
It had better not to have many IGMP query to save the resources. If you are not sure of the forwarding relationship
of the unknown multicast group, please choose all the ports.
Static Multicast FWD
The device provides the function of static MAC address forwarding. The destination address includes the
data packets with static MAC address which will be transferred to the appointed port. Embedded forwarding
address list in the switch chip can learn and support 4,000 MAC addresses and 256 multicast forwarding
ports list.
Bottoms [Add] and [Delete] are used to add and delete static MAC address. Static MAC Address asks the
user to input a valid address. If it is not valid, a warning ejects. Join port is used to choose MAC address
forwarding port. You can appoint one or more forwarding ports. Click [Add] and [Delete] to update static MAC
address forwarding.
IGMP Notes
1.
This function has great impact on forwarding multicast, unless you can make sure the address is no problem,
otherwise, please use it with caution.
2.
The following multicast addresses are reserved for the device or protocol, please don't use them:
0180C20000xx, 01005E0000xx.
3.
IGMP dynamic learning will not update the multicast address, static multicast forwarding is a kind of safety
mechanism.
