attribute (Affinity attribute mapping view)

Function

The attribute command configures the mappings between affinity bit values and names.

The undo attribute command deletes the mappings between affinity bit values and names.

By default, no names are specified for affinity bits.

Format

attribute bit-name bit-sequence bit-number

undo attribute bit-name

Parameters

Parameter	Description	Value
bit-name	Specifies the name of an affinity bit.	The name is a string of 1 to 31 characters.
bit-sequence bit-number	Specifies the sequence number of an affinity bit.	The value is an integer ranging from 0 to 127. Value 0 indicates the left-most bit, and value 127 indicates the right-most bit.

Usage Guidelines

Usage Scenario

Before configuring names for affinity and link administrative group bits, mappings between affinity bits and names must be configured on each node that is used to calculate a path for an MPLS TE tunnel. To configure the mappings between affinity bit values and names, run the attribute command.

Prerequisites

An affinity name template has been created using the path-constraint affinity-mapping command.

Precautions

The mappings on each node must be the same to achieve a semantic consistency during path calculation.

Example

# Name the third bit in an affinity yellow.

<HUAWEI> system-view
[~HUAWEI] mpls
[*HUAWEI-mpls] mpls te
[*HUAWEI-mpls] quit
[*HUAWEI] path-constraint affinity-mapping
