Igmp Snooping - SMC Networks SMC TigerStack III SMC6824M Management Manual

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 SMC6824MPE switch ports by requiring
users to first enter a user ID and password for authentication.
IEEE 802.3ac
Defines frame extensions for VLAN tagging.
IEE 802.3af (PoE)
An IEEE standard for providing Power over Ethernet (PoE) capabilities. When
Ethernet is passed over copper cable, two twisted pairs are used for data transfer,
and two twisted pairs are unused. With PoE, power can either be passed over the
two data pairs or over the two spare pairs.
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.)

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.
