mechanism supported by associated client stations. For example, if you set VSC-based low priority,
then all devices that connect to the VSC have their traffic set at this priority, including SVP clients.

DiffServ (Differentiated Services)
This mechanism classifies traffic based on the value of the Differentiated Services (DS) codepoint
field in IPv4 and IPv6 packet headers (as defined in RFC2474). The codepoint is composed of the
six most significant bits of the DS field.
DiffServ (DS codepoint value)Queue
111000 (Network control)1
110000 (Internetwork control)
101000 (Critical)2
100000 (Flash override)
011000 (Flash)3
000100 (Routine)
010000 (Immediate)4
001000 (Priority)
TOS
This mechanism classifies traffic based on value of the TOS (Type of Service) field in an IP packet
header.
TOS (Type of Service field value)Queue
0x30, 0xE0, 0x88, 0xB81
0x28, 0xA02
0x08, 0x203
All other TOS traffic4
IP QoS
This option lets you assign traffic to the queues based on the criteria in one or more IP QoS profiles.
Each profile lets you target traffic on specific ports or using specific protocols.
Disabled
When QoS traffic prioritization is disabled, all traffic is sent to queue 3.
IP QoS profiles
This option is only available if you set the Priority mechanism to IP QoS.
Select the IP QoS profiles to use for this profile. To add QoS profiles to the list, use the Controller
>> Network > IP QoS page.
