RSTP Port Configuration
Port: The port ID can’t be changed. “Aggregations” refers to any configured trunk group.
Protocol Enabled: Click to enable (checked) or disable (default). When checked, you’re enabling RSTP for this port as per the configuration in the RSTP Port Configuration menu.
Edge: The default setting is enabled (checked); click to disable (unchecked). Edge ports don’t participate in the Spanning Tree Protocol, but still send configuration messages, linking to an end station or another STP device.
Path Cost: This parameter is used by the STP to determine the best path between devices. Lower values should be assigned to ports attached to faster media; higher values for slower media. Set the RSTP pathcost on the port. Enter a value from 0 to 200000000 or keep the default setting (Auto).
IGMP Snooping
Internet Group Management Protocol (IGMP) Snooping is the process of listening to IGMP network traffic. As implied by the name, IGMP Snooping is a feature that allows a Layer 2 switch to “listen in” on the IGMP conversation between hosts and routers by processing the Layer 3 IGMP packets sent in a multicast network. When enabled in a switch, IGMP Snooping analyzes all IGMP packets between hosts connected to the switch and multicast routers in the network. When a switch hears an IGMP report from a host for a given multicast group, the switch adds the host’s port number to the multicast list for that group. And when the switch hears an IGMP “leave,” it removes the host’s port from the table entry. As a result, this feature prevents flooding of IP multicast traffic and limits
