In a hub or an unmanaged switch, the uplink port (the port to which the hub is connected) should be set in multi-session mode. A supplicant, in some contexts, refers to a user or to a client in a network environment seeking to access network resources secured by the IEEE 802.1X authentication mechanism.
Unmanaged switch es have no configuration interface or options. They are plug and play. They are typically the least expensive switches, and therefore often used in a small office/home office environment. Unmanaged switches can be desktop or rack mounted. [28] Managed switches have one or more
4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.

Avaya 5600 Family of stackable switches. A stackable switch is a network switch that is fully functional operating standalone but which can also be set up to operate together with one or more other network switches, with this group of switches showing the characteristics of a single switch but having the port capacity of the sum of the combined switches.
IGMP snooping is designed to prevent hosts on a local network from receiving traffic for a multicast group they have not explicitly joined. It provides switches with a mechanism to prune multicast traffic from links that do not contain a multicast listener (an IGMP client). Essentially, IGMP snooping is a layer 2 optimization for the layer 3 IGMP.
However, as soon as either end of the connection attempts to send any significant amount of data, the network suddenly slows to very low speed. Since the network is otherwise working, the cause is not so readily apparent. A duplex mismatch causes problems when both ends of the connection attempt to transfer data at the same time.
