pair of ICMP messages on multicast links. It eliminates the need to configure router
addresses manually, and is independent of any specific routing protocol.
7.1.9.Internet Control Message Protocol (ICMP)
Commonly used to send echo messages (i.e., Ping) for monitoring purposes.
7.1.10.IEEE 802.1D
Specifies a general method for the operation of MAC bridges, including the Spanning
Tree Protocol.
7.1.11.IEEE 802.1Q
VLAN Tagging—Defines Ethernet frame tags which carry VLAN information. It allows
switches to assign endstations to different virtual LANs, and defines a standard way for
VLANs to communicate across switched networks.
7.1.12.IEEE 802.3ac
Defines frame extensions for VLAN tagging.
7.1.13.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.
7.1.14.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.
7.1.15.In-Band Management
Management of the network from a station attached directly to the network.
7.1.16.IP Multicast Filtering
A process whereby this switch can pass multicast traffic along to participating hosts.
7.1.17.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.
