Generic Multicast Registration Protocol. GMRP allows network devices to
GMRP
register end stations with multicast groups. GMRP requires that any
participating network devices or end stations comply with the IEEE 802.1p
standard.
Specifies a general method for the operation of MAC bridges, including the
IEEE 802.1D
Spanning Tree Protocol.
VLAN Tagging—Defines Ethernet frame tags which carry VLAN information.
IEEE 802.1Q
It allows switches to assign endstations to different virtual LANs, and
defines a standard way for VLANs to communicate across switched
networks.
An IEEE standard for providing quality of service (QoS) in Ethernet
IEEE 802.1
P
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.
An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which
IEEE 802.1
S
provides independent spanning trees for VLAN groups.
An IEEE standard for the Rapid Spanning Tree Protocol (RSTP) which
IEEE 802.1
W
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)
Port Authentication controls access to the switch ports by requiring users to
IEEE 802.1X
first enter a user ID and password for authentication.
Defines frame extensions for VLAN tagging.
IEEE 802.3
AC
Defines Ethernet frame start/stop requests and timers used for flow control
IEEE 802.3
X
on full-duplex links. (Now incorporated in IEEE 802.3-2002)
Internet Group Management Protocol. A protocol through which hosts can
IGMP
register with their local router for multicast services. If there is more than
one multicast switch/router on a given subnetwork, one of the devices is
made the "querier" and assumes responsibility for keeping track of group
membership.
