Glossary 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. Link Aggregation Control Protocol (LACP) Allows ports to automatically negotiate a trunked link with LACP-configured ports on another device. Management Information Base (MIB) An acronym for Management Information Base. It is a set of database objects that contains information about a specific device. MD5 Message-Digest Algorithm An algorithm that is used to create digital signatures. It is intended for use with 32 bit machines and is safer than the MD4 algorithm, which has been broken. MD5 is a one-way hash function, meaning that it takes a message and converts it into a fixed string of digits, also called a message digest. Glossary-3
