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.
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.
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 802.1p
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 802.1s
An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which provides
independent spanning trees for VLAN groups.
IEEE 802.1w
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 802.3ac
Defines frame extensions for VLAN tagging.
IEEE 802.3x
Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex
links. (Now incorporated in IEEE 802.3-2002)
