Gbps, or 10G for 10 Gbps) and the duplex (F for full duplex or H for half). It also shows the cable

Speed.
IGMP Leave
Mode
This displays Immediate when the Switch receives IGMP leave packets, the Switch will close the
multicast stream immediately without any further action.
This displays Fast when the Switch will further generate a group specific query packet to all the
receivers. This could prevent the traffic being cut if some receivers still want to receive the
multicast stream.
This displays Normal when the Switch receives an IGMP leave message from a host on a port, it
forwards the message to the multicast router. The multicast router then sends out an IGMP
Group-Specific Query (GSQ) message to determine whether other hosts connected to the port
should remain in the specific multicast group. The Switch forwards the query message to all hosts
connected to the port and waits for IGMP reports from hosts to update the forwarding table for
this port.
