configure qostype ingress priority

configure qostype ingress priority [diffserv | dot1p | vlan | application]
<qos-priority (0-15)>
Description
Configures the relative priority among the different ingress queue selection criteria.
Syntax Description
diffserv
dot1p
vlan
application
qos-priority (0-15)
Default
• diffserv—3
• dot1p—1
• vlan—2
• application—5
Usage Guidelines
Ingress QoS types with a greater value take higher precedence.
The queue selection criteria with the highest priority, if enabled in the received packet, is used first,
followed by the remaining criteria in descending order.
The priority range is 0-15 (15 is the highest priority). Each queue selection criteria must have a unique
priority; no two selection criteria can have the same priority range.
All VLANs are set to the default ingress QoS profile none.
Congestion can cause ingress traffic to be dropped on oversubscribed
QoS allows received traffic with different VLAN priority values, different DiffServ code points (IP TOS),
or from different VLANS to be classified to up to eight different ingress queues. This allows for
specified traffic types to be queued separately so they remain unaffected by congestion in other ingress
queues.
To configure which DiffServ code points map to which ingress QoS profiles, use the command:
configure diffserv examination code-point <code-point> qosprofile <qosprofile> ports
[<portlist> | all]
