NETGEAR 24-Port Gigabit Smart Managed Pro Switch with PoE+ and 2 SFP Ports Model GS724TPv2
Two basic types of QoS are supported:
Integrated Services. Network resources are apportioned based on request and are
reserved (resource reservation) according to network management policy (RSVP, for
example).
Differentiated Services. Network resources are apportioned based on traffic
classification and priority, giving preferential treatment to data with strict timing
requirements.
The switch supports DiffServ.
The DiffServ feature contains a number of conceptual QoS building blocks that you can use
to construct a differentiated service network. Use these same blocks in different ways to build
other types of QoS architectures.
You must configure three key QoS building blocks for DiffServ:
Class
Policy
Service (the assignment of a policy to a directional interface)
Class
You can classify incoming packets at Layers 2, 3, and 4 by inspecting the following
information for a packet:
Source/destination MAC address
EtherType
Class of Service (802.1p priority) value (first/only VLAN tag)
VLAN ID range (first/only VLAN tag)
Secondary 802.1p priority value (second/inner VLAN tag)
Secondary VLAN ID range (second/inner VLAN tag)
IP Service Type octet (also known as: ToS bits, Precedence value, DSCP value)
Layer 4 protocol (TCP, UDP and so on)
Layer 4 source/destination ports
Source/destination IP address
From a DiffServ point of view, two types of classes exist:
DiffServ traffic classes
DiffServ service levels/forwarding classes
