qos phb enable vlan

Function

The qos phb enable vlan command enables priority mapping on the outbound interface.

The undo qos phb enable vlan command disables priority mapping on the outbound interface.

By default, an interface does not check the PHB table when forwarding packets downstream.

Format

qos phb enable { ds-name | default } [ vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> ]

undo qos phb enable [ vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> ]

Parameters

Parameter	Description	Value
ds-name	Specifies the name of a DS domain.	The value is a string of 1 to 48 case-sensitive characters.
default	Specify default domain.	-
vlan	Indicates VLAN configuration on a Layer 2 interface.	-
vlan-id1	Specifies a start VLAN ID.	The value is an integer ranging from 1 to 4094.
to vlan-id2	Specifies an end VLAN ID.	The value is an integer ranging from 1 to 4094. vlan-id2 must be greater than vlan-id1.

Usage Guidelines

Usage Scenario

This command indicates that a DS domain is bound to the Layer 2 interface based on Layer 2 VLAN packets to implement priority mappings for the VLAN packets.

As defined in simple traffic classification, external priorities of upstream packets are mapped to internal priorities based on the behavior aggregate (BA) table; internal priorities of downstream packets are mapped to external priorities based on the PHB table.

After the qos phb enable command is used on the outbound interface, internal priorities of the outgoing packets on the interface are mapped to external priorities based on the PHB table.

# Enable PHB for VLAN 1 to VLAN 10 on the Layer 2 interface GE 0/1/0.
