Ip Multicast Filtering; Link Aggregation - SMC Networks 8748L2 Management Manual

LOSSARY
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.
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.
In-Band Management
Management of the network from a station attached directly to the
network.

IP Multicast Filtering

A process whereby this switch can pass multicast traffic along to
participating hosts.
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.
