IGMP (Internet Group Management Protocol)

A standard protocol that lets you originate multiple IP tunnels using one IP multicast address. IGMP allows IP multicast frames to be routed to remote IP subnets that have hosts participating in the multicast group. By enabling IGMP, access points can act as IP hosts and participate in an IP multicast group.

inbound frames

Frames moving toward the primary LAN.

IP router

A software and hardware connection between two or more subnetworks that permits traffic to be routed from one network to another on the basis of the intended destinations.

IP subnet

A single member of the collection of hardware networks that comprise an IP network. Host addresses on a given subnet share an IP network number with hosts on all other subnets of the IP network. The local address is divided into subnet-number and host-number fields to indicate which subnet a host is on.

IP tunneling

IP tunneling is used on networks with routers. IP tunneling allows wireless end devices to roam across IP subnet boundaries without losing connection. IP tunneling encapsulates standard IP frames with Generic Routing Encapsulation (GRE) and forwards the frames from the root access point on a home IP subnet to another access point on a remote IP subnet. IP tunneling is done through the access points’ logical IP ports.

MAC address

There are two types of MAC addresses: unicast and broadcast. Unicast specifies a single Ethernet interface, while multicast specifies a group of Ethernet addresses. Broadcast is a variation of multicast in which a multicast is received by all interfaces.

MIB (Management Information Base)

This repository stores network traffic information that SNMP management programs collect. Your network administrator can use management software interacting with the MIB to obtain information about network
