ICMP
Internet Control Message Protocol is a network layer protocol that reports
errors in processing IP packets. ICMP is also used by routers to feed back
information about better routing choices.
IGMP
Internet Group Management Protocol. 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.
IGMP P
ROXY
Proxies multicast group membership information onto the upstream
interface based on IGMP messages monitored on downstream interfaces,
and forwards multicast traffic based on that information. There is no need
for multicast routing protocols in an simple tree that uses IGMP Proxy.
IGMP Q
UERY
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.
IGMP S
NOOPING
Listening to IGMP Query and IGMP Report packets transferred between IP
Multicast Routers and IP Multicast host groups to identify IP Multicast
group members.

ANAGEMENT
Management of the network from a station attached directly to the
network.

ULTICAST
F
ILTERING
A process whereby this switch can pass multicast traffic along to
participating hosts.
IP P
RECEDENCE
The Type of Service (ToS) octet in the IPv4 header includes three
precedence bits defining eight different priority levels ranging from highest
priority for network control packets to 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.
LACP
Link Aggregation Control Protocol. Allows ports to automatically negotiate
a trunked link with LACP-configured ports on another device.
L
AYER
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.
