Configuring Basic QoS
Configuration Guidelines
Select the QoS mode according to your network requirements. Three QoS modes are
supported on the switch: Port Based, 802.1P Based and DSCP Based.
Port Based
In this mode, the switch prioritizes packets according to their ingress ports, regardless of
the packet field or type. The port based QoS mode supports four priority queues, which are
labeled as 1, 2, 3, and 4.
802.1P Based
802.1P defines the first three bits in 802.1Q Tag as PRI field. The PRI values are from 0 to 7.
802.1P determines the priority of packets based on the PRI value.
In this mode, the switch only prioritizes packets with VLAN tag, regardless of the IP header
of the packets.
DSCP Based
DSCP (Differentiated Services Code Point) determines the priority of packets based on
the ToS (Type of Service) field in their IP header. RFC2474 re-defines the ToS field in the IP
packet header as DS field. The first six bits (bit 0-bit 5) of the DS field is used to represent
DSCP priority. The DSCP values are from 0 to 63.
In this mode, the switch only prioritizes IP packets.
Note:
The switch works in one and only one QoS mode at any time. When a specific QoS mode is
enabled, the other two QoS modes will be disabled automatically.
