Table 12-17: QoS Settings Parameter Descriptions
Parameter Description
Media Premium QoS
media-qos
[PremiumServiceClassMediaDiffServ]
Defines the DiffServ value for Premium Media CoS content.
The valid range is 0 to 63. The default is 46.
Note: You can also configure the the parameter per IP
Profile (IpProfile_IPDiffServ) or Tel Profile
(TelProfile_IPDiffServ).
Control Premium QoS
control-qos
[PremiumServiceClassControlDiffServ]
Defines the DiffServ value for Premium Control CoS content
(Call Control applications).
The valid range is 0 to 63. The default is 40.
Note: You can also configure the the parameter per IP
Profile (IpProfile_SigIPDiffServ) or Tel Profile
(TelProfile_SigIPDiffServ).
Gold QoS
gold-qos
[GoldServiceClassDiffServ]
Defines the DiffServ value for Gold CoS content (streaming
applications).
The valid range is 0 to 63. The default is 26.
Bronze QoS
bronze-qos
[BronzeServiceClassDiffServ]
Defines the DiffServ value for Bronze CoS content (OAMP
applications).
The valid range is 0 to 63. The default is 10.
12.8.2 Configuring DiffServ-to-VLAN Priority Mapping
The QoS Mapping table lets you configure up to 64 DiffServ-to-VLAN priority mapping for
Layer 3 and Layer-2 Quality of Service (QoS). For each packet sent to the LAN, the VLAN
Priority of the packet is set according to the DiffServ value in the IP header of the packet.
Layer-2 802.1Q frames have a 2-byte field called Tag Control Information. The three most
significant bits of this 2-byte field represents the Class of Service (CoS) value. Layer-2 QoS
is represented by this CoS value which is from 0 to 7 (thus 8 values). Layer-2 QoS
parameters define the values for the 3 priority bits in the VLAN tag according to the value
of the DiffServ field in the packet IP header (according to the IEEE 802.1p standard).
Differentiated Services (DiffServ) is an architecture providing different types or levels of
service for IP traffic. DiffServ (according to RFC 2474), prioritizes certain traffic types
based on priority, accomplishing a higher-level QoS at the expense of other traffic types.
By prioritizing packets, DiffServ routers can minimize transmission delays for time-sensitive
packets such as VoIP packets.
The following procedure describes how to configure DiffServ-to-VLAN priority mapping
through the Web interface. You can also configure it through ini file (DiffServToVlanPriority)
or CLI (configure network > qos vlan-mapping).
 To configure DiffServ-to-VLAN priority mapping:
1. Open the QoS Mapping table (Setup menu > IP Network tab > Quality folder > QoS
Mapping).
