ERVICE
Differentiated Services (DiffServ) provides policy-based management
mechanisms used for prioritizing network resources to meet the
requirements of specific traffic types. 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.

NOOPING
This feature enables the DHCP Snooping to include information
about client when forwarding DHCP requests from a DHCP client to a
DHCP server via Trust Port. DHCP snooping can be configured on
LAN switches to harden the security on the LAN to only allow clients
with specific IP/MAC addresses to have access to the network. In
short, DHCP snooping ensures IP integrity on a Layer 2 switched
domain.
