6.4.5 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.
Button [Add/Edit], [Delete] were used for add/delete static Multicast MAC address. All none multicast
address did not allow to add in this table and the format must according to XX-XX-XX-XX-XX-XX, did not
have space or other illegal character, otherwise, will be display warning information. For example, add
address "01-22-6F-01-02-03" member is port 2, 3, 4, and then data frame of destination address can just
send to port 02, 03, and 04.
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.
