ERVICE
Differentiated Services (DiffServ) provides policy-based management
mechanisms used for prioritizing network resources to meet the
requirements of specific traffic types on a per-hop basis. Each packet is
classified upon entry into the network based on access lists, DSCP values,
or VLAN lists. Using access lists allows you select traffic based on Layer 2,
Layer 3, or Layer 4 information contained in each packet. Based on
network policies, different kinds of traffic can be marked for different kinds
of forwarding.

ILTERING
Specific multicast traffic can be assigned to its own VLAN to ensure that it
does not interfere with normal network traffic and to guarantee real-time
delivery by setting the required priority level for the designated VLAN. The
switch uses IGMP Snooping and Query to manage multicast group
registration for IPv4 traffic, and MLD Snooping for IPv6 traffic. It also
supports Multicast VLAN Registration (MVR) which allows common
multicast traffic, such as television channels, to be transmitted across a
single network-wide multicast VLAN shared by hosts residing in other
standard or private VLAN groups, while preserving security and data
isolation for normal traffic.
