IEEE 802.3X
Defines Ethernet frame start/stop requests and timers used for flow control on full-
duplex links. (Now incorporated in IEEE 802.3-2002)
Internet Group Management Protocol (IGMP)
A protocol through which hosts can register with their local Router for Multicast
services. If there is more than one Multicast Switch/Router on a given subnetwork,
one of the devices is made the “querier” and assumes responsibility for keeping track of
group membership.
IGMP Snooping
Listening to IGMP Query and IGMP report packets transferred between IP Multicast
Routers and IP Multicast host groups to identify IP Multicast group members.
IGMP Query
On each subnetwork, one IGMP-capable device will act as the querier — that is, the
device that asks all hosts to report on the IP Multicast groups they wish to join or to
which they already belong. The elected querier will be the device with the lowest IP
Address in the subnetwork.
IP Multicast Filtering
Allows or denies the Client to add the specified Multicast group.
Multicast Switching
A process whereby the Switch filters incoming Multicast frames for services for which
no attached host has registered, or forwards them to all Ports contained within the
designated Multicast group.
Layer 2
Data Link layer in the ISO 7-Layer Data Communications Protocol. This is related directly
to the hardware interface for Network devices and passes on traffic based on MAC
addresses.
Link Aggregation (See Port Trunk).
Link Aggregation Control Protocol (LACP)
Allows Ports to automatically negotiate a trunked link with LACP-configured Ports on
another device.
