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)
