As a result, 32 IP multicast addresses are mapped to the same MAC address. ¾ Multicast Address Table The switch is forwarding multicast packets based on the multicast address table. As the - TP-Link TL-SL2218 | TL-SL2218 V1 User Guide - Page 82
, including four submenus: IGMP Snooping, Multicast IP, Multicast Filter and Packet Statistics. 8.1 IGMP Snooping ¾ IGMP Snooping Process The switch, running IGMP Snooping, listens to the IGMP messages transmitted between the host and the router, and tracks the IGMP messages and the registered - TP-Link TL-SL2218 | TL-SL2218 V1 User Guide - Page 83
to the multicast router. Member Port: Indicates a switch port connected to a multicast group member. 2. Timers Router Port Time: Within the time, if the switch does not receive IGMP query message from the router port, it will consider this port is not a router port any more. The default value is 300 - TP-Link TL-SL2218 | TL-SL2218 V1 User Guide - Page 84

congested, the problem that many packets compete for resources must be solved, usually in the way of queue scheduling. The switch supports four schedule modes: SP, WRR, SP+WRR and Equ. ¾ Priority Mode This switch implements three priority modes based on port, on 802.1P and on DSCP. By default, the - TP-Link TL-SL2218 | TL-SL2218 V1 User Guide - Page 98
switch processes untagged packets based on the default priority mode. 3.
