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 802.1X
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.
IGMP Snooping
Listening to IGMP Query and IGMP Report packets transferred between IP
Multicast Routers and IP Multicast host groups to identify IP Multicast group
members.
IGMP Query
On each subnetwork, one IGMP-capable device will act as the querier — that is,
the device that asks all hosts to report on the IP multicast groups they wish to join
or to which they already belong. The elected querier will be the device with the
lowest IP address in the subnetwork.
