MPLS QoS commands

if-match mpls-exp

Use if-match mpls-exp to define a criterion to match the EXP field in the first MPLS label.

Use undo if-match mpls-exp to delete the match criterion.

Syntax

if-match [ not ] mpls-exp exp-value&<1-8>

undo if-match [ not ] mpls-exp exp-value&<1-8>

Default

No criterion is defined to match the EXP field in the first MPLS label.

Views

Traffic class view

Predefined user roles

network-admin

Parameters

not: Matches packets not conforming to the specified criterion.

exp-value&<1-8>: Specifies a space-separated list of up to eight EXP values. The value range for the exp-value argument is 0 to 7. If the same EXP value is specified multiple times, the system considers them as one. If a packet matches one of the defined MPLS EXP values, it matches the if-match clause.

Examples

# In traffic behavior database, define a criterion to match packets with EXP value 3 or 4 in the first MPLS label.

<Sysname> system-view

[Sysname] traffic classifier database

[Sysname-classifier-database] if-match mpls-exp 3 4

if-match second-mpls-exp

Use if-match second-mpls-exp to define a criterion to match the EXP field in the second MPLS label.

Use undo if-match second-mpls-exp to delete the match criterion.

Syntax

if-match [ not ] second-mpls-exp exp-value&<1-8>

undo if-match [ not ] second-mpls-exp exp-value&<1-8>

Default

No criterion is defined to match the EXP field in the second MPLS label.

Parameters

not: Matches packets not conforming to the specified criterion.

exp-value&<1-8>: Specifies a space-separated list of up to eight EXP values. The value range for the exp-value argument is 0 to 7. If the same MPLS EXP value is specified multiple times, the system considers them as one. If a packet matches one of the defined MPLS EXP values, it matches the if-match clause.

Examples

# In traffic behavior database, define a criterion to match packets with EXP value 3 or 4 in the second MPLS label.

<Sysname> system-view

[Sysname] traffic classifier database

[Sysname-classifier-database] if-match second-mpls-exp 3 4

remark mpls-exp

Use remark mpls-exp to configure an action of marking the EXP value in the first label in a traffic behavior.

Use undo remark mpls-exp to delete the action.

Syntax

remark mpls-exp exp-value

undo remark mpls-exp

Default

No action of marking the EXP value in the first label is configured in a traffic behavior.

Views

Predefined user roles

network-admin

Parameters

exp-value: Specifies an EXP value in the range of 0 to 7.

Usage guidelines

This command takes effect only when the QoS policy is applied to the outbound direction.

Examples

# In traffic behavior database, set the EXP value in the first label to 0 for MPLS packets.

<Sysname> system-view

[Sysname] traffic behavior database

[Sysname-behavior-database] remark mpls-exp 0

remark second-mpls-exp

Use remark second-mpls-exp to configure an action of marking the EXP value in the second MPLS label in a traffic behavior.

Use undo remark second-mpls-exp to delete the action.

Syntax

remark second-mpls-exp exp-value

undo remark second-mpls-exp

Default

No action of marking the EXP value in the second MPLS label is configured in a traffic behavior.

Parameters

exp-value: Specifies an EXP value in the range of 0 to 7.

Examples

# In traffic behavior database, set the EXP value in the second MPLS label to 0 for MPLS packets.
