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.
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 router on a given subnetwork, one of
the routers 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.
IP Precedence
The Type of Service (ToS) octet in the IPv4 header includes three precedence bits
defining eight different priority levels ranging from the highest priority for network
control packets to the lowest priority for routine traffic. The eight values are
mapped one-to-one to the Class of Service categories by default, but may be
configured differently to suit the requirements for specific network applications.
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.
Layer 3
Network layer in the ISO 7-Layer Data Communications Protocol. This layer
handles the routing functions for data moving from one open system to another.
Link Aggregation
See Port Trunk.
