IGMP Snooping
Running at the data link layer, IGMP Snooping is a multicast control
mechanism on the Layer 2 Ethernet switch and it is used for multicast
group management and control. This document describes:

MLD Snooping
Multicast Listener Discovery Snooping (MLD Snooping) is an IPv6
multicast constraining mechanism that runs on Layer 2 devices to
manage and control IPv6 multicast groups. This document describes:

Features Description
QoS Overview
For network traffic, the Quality of Service (QoS) involves bandwidth, delay,
and packet loss rate during traffic forwarding process. This document
describes:
z Introduction to QoS
z Introduction to QoS Service Models
z QoS Techniques Overview
QoS Configuration
Approaches
Two approaches are available for you to configure QoS: policy-based and
non policy-based. This document describes:
z QoS Configuration Approach Overview
z Configuring a QoS Policy
Priority Mapping
The priorities of a packet determine its transmission priority. There are two
types of priority: priorities carried in packets and priorities locally assigned
for scheduling only.
When a packet enters the device from a port, the device assigns a set of
QoS priority parameters to the packet based on a certain priority and
sometimes may modify its priority, according to certain rules depending on
device status. This process is called priority mapping.
