mpls-exp-inbound

Function

The mpls-exp-inbound command maps EXP priorities of MPLS packets to PHBs and colors in a DiffServ domain on an inbound interface.

The undo mpls-exp-inbound command restores the default mapping.

The following table shows the default mappings from EXP priorities to PHBs and colors of MPLS packets in a DiffServ domain on an inbound interface.

**Table 1** Default mappings from EXP priorities to PHBs and colors of MPLS packets in a DiffServ domain on an inbound interface
EXP Priority	PHB	Color
0	BE	green
1	AF1	green
2	AF2	green
3	AF3	green
4	AF4	green
5	EF	green
6	CS6	green
7	CS7	green

Format

mpls-exp-inbound exp-value phb service-class [ color ]

undo mpls-exp-inbound [ exp-value ]

Parameters

Parameter	Description	Value
exp-value	Specifies the EXP priority of an MPLS packet.	The value is an integer ranging from 0 to 7. A larger value indicates a higher EXP priority of MPLS packets.
service-class	Specifies a PHB.	The value can be BE, AF1 to AF4, EF, CS6, or CS7.
color	Specifies the color of a packet.	The value can be green, yellow, or red.

Usage Guidelines

To implement QoS scheduling on the MPLS packets that come from the upstream device, run the mpls-exp-inbound command to map EXP priorities of MPLS packets to PHBs and colors. After a DiffServ domain is bound to the inbound interface of packets, the QoS mechanism performs congestion management and congestion avoidance according to PHBs and colors of the packets.

Example

# In the DiffServ domain ds1, map EXP priority 2 of MPLS packets to PHB AF1 and color incoming MPLS packets as yellow.
