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 username 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 endstations with multicast groups.
GMRP requires that any participating network devices or endstations comply with
the IEEE 802.1p standard.
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the CSMA/
CD access method.
Group Attribute Registration Protocol
See Generic Attribute Registration Protocol.
IEEE 802.1D
Specifies a general method for the operation of MAC bridges, including the
Spanning Tree Protocol.
