C-10 Glossary
Full-duplex
A system that allows packets to be transmitted and received at the same time and, in effect, doubles the
potential throughput of a link.

GARP
See “Generic Attribute Registration Protocol.” on page 10.
GARP Information Propagation
GIP is the propagation of information between GARP participants for the same application in a bridge is
carried out by a GIP component.
GARP Multicast Registration Protocol
GMRP provides a mechanism that allows Bridges and end stations to dynamically register (and
subsequently, de-register) Group membership information with the MAC Bridges attached to the same LAN
segment, and for that information to be disseminated across all Bridges in the Bridged LAN that support
Extended Filtering Services. The operation of GMRP relies upon the services provided by the GARP.
GARP VLAN Registration Protocol.
GVRP allows workstations to request admission to a particular VLAN for multicast purposes.
Gateway
A local device, usually a router, that connects hosts on a local network to other networks.
GE
See “Gigabit Ethernet” on page 10.
General Purpose Chip-select Machine
GPCM provides interfacing for simpler, lower-performance memory resources and memory
mapped-devices. The GPCM does not support bursting and is used primarily for boot-loading.
Generic Attribute Registration Protocol.
GARP provides a generic attribute dissemination capability that is used by participants in GARP
Applications (called GARP Participants) to register and de-register attribute values with other GARP
Participants within a Bridged LAN. The definition of the attribute types, the values that they can carry, and
the semantics that are associated with those values when registered are specific to the operation of the GARP
Application concerned.
Gigabit Ethernet
An Ethernet system that is designed to operate at 1000 Mbps (1 Gbps).
