Dynamic Host Control Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a TCP/IP
network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability
of automatic allocation of reusable network addresses and additional configuration
options.
Extended Universal Identifier (EUI)
An address format used by IPv6 to identify the host portion of the network address.
The interface identifier in EUI compatible addresses is based on the link-layer (MAC)
address of an interface. Interface identifiers used in global unicast and other IPv6
address types are 64 bits long and may be constructed in the EUI-64 format. The
modified EUI-64 format interface ID is derived from a 48-bit link-layer address by
inserting the hexadecimal number FFFE between the upper three bytes (OUI field)
and the lower 3 bytes (serial number) of the link layer address. To ensure that the
chosen address is from a unique Ethernet MAC address, the 7th bit in the high-order
byte is set to 1 (equivalent to the IEEE Global/Local bit) to indicate the uniqueness of
the 48-bit address.
Extensible Authentication Protocol over LAN (EAPOL)
EAPOL is a client authentication protocol used by this switch to verify the network
access rights for any device that is plugged into the switch. A user name and
password is requested by the switch, and then passed to an authentication server
(e.g., RADIUS) for verification. EAPOL is implemented as part of the IEEE 802.1X
Port Authentication standard.
GARP VLAN Registration Protocol (GVRP)
Defines a way for switches to exchange VLAN information in order to register
necessary VLAN members on ports along the Spanning Tree so that VLANs defined
in each switch can work automatically over a Spanning Tree network.
Generic Attribute Registration Protocol (GARP)
GARP is a protocol that can be used by endstations and switches to register and
propagate multicast group membership information in a switched environment so
that multicast data frames are propagated only to those parts of a switched LAN
containing registered endstations. Formerly called Group Address Registration
Protocol.
Generic Multicast Registration Protocol (GMRP)
GMRP allows network devices to register end stations with multicast groups. GMRP
requires that any participating network devices or end stations comply with the IEEE
802.1p standard.
Group Attribute Registration Protocol (GARP)
