GMRP

Generic Multicast Registration Protocol. 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.

GVRP

GARP VLAN Registration Protocol. 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.

IEEE 802.1D

Specifies a general method for the operation of MAC bridges, including the
Spanning Tree Protocol.

IEEE 802.1Q

VLAN Tagging—Defines Ethernet frame tags which carry VLAN information.

It allows switches to assign endstations to different virtual LANs, and

defines a standard way for VLANs to communicate across switched

networks.

IEEE 802.1

P

An IEEE standard for providing quality of service (QoS) in Ethernet

networks. The standard uses packet tags that define up to eight traffic

classes and allows switches to transmit packets based on the tagged

priority value.

IEEE 802.1

S

An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which

provides independent spanning trees for VLAN groups.

IEEE 802.1

W

An IEEE standard for the Rapid Spanning Tree Protocol (RSTP) which

reduces the convergence time for network topology changes to about 10%

of that required by the older IEEE 802.1D STP standard. (Now incorporated

in IEEE 802.1D-2004)

IEEE 802.1X

Port Authentication controls access to the switch ports by requiring users to

first enter a user ID and password for authentication.

IEEE 802.3

AC

Defines frame extensions for VLAN tagging.

IEEE 802.3

X

Defines Ethernet frame start/stop requests and timers used for flow control

on full-duplex links. (Now incorporated in IEEE 802.3-2002)

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.
