Multicast Group | For examples, 224.0.0.1 is for all hosts in this subnet, 224.0.0.2 is for all multicast |
| routers in this subnet, etc. A router will not forward a packet with the destination IP |
| address within this range. See the IANA web site for more information. |

| multicast address. Select Drop to discard the frame(s). Select Flooding to send |
| the frame(s) to all ports. |

| query port. |
| Select Auto to have the Switch use the port as an IGMP query port if the port |
| receives IGMP query packets. |
| Select Fixed to have the Switch always use the port as an IGMP query port. |
| Select this when you connect an IGMP multicast server to the port. |
| Select Edge to stop the Switch from using the port as an IGMP query port. The |
| Switch will not keep any record of an IGMP router being connected to this port. |
