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.
GE. See “Gigabit Ethernet” on
page 335.
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. A high-speed
Ethernet connection.
GIP. See “GARP Information
Propagation” on page 334.
GMRP. See “GARP Multicast
Registration Protocol” on page 334.
GPCM. See “General Purpose
Chip-select Machine” on page 335.
GVD. GARP VLAN Database.
GVRP. See “GARP VLAN
Registration Protocol.” on page 335.
H
.h file. Header file in C code.
Contains function and coding
definitions.
HAPI. See “Hardware Abstraction
Programming Interface” on
page 335.
Hardware Abstraction
Programming Interface. HAPI is
the module that contains the NP
specific software that interacts with
the hardware.
hop count. The number of routers
that a data packet passes through
on its way to its destination.
I
ICMP. See “Internet Control
Message Protocol” on page 336.
