QUALITY OF SERVICE 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.

MULTICAST FILTERING 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.

SYSTEM DEFAULTS

The switch’s system defaults are stored in a non-volitile memory. To reset

the switch defaults, see "Restoring Factory Defaults" on page 288.

The following table lists some of the basic system defaults.
