te-class0

Function

The te-class command configures a TE-class.

The undo te-class command deletes a TE-class.

By default, no TE-class is set.

Parameters

Parameter	Description	Value
class-type	Indicates the service type.	The IETF-mode DiffServ-aware Traffic Engineering (DS-TE) supports eight service types, namely, CT0 to CT7.
ct0	Specifies service type 0.	-
ct1	Specifies Class-Type 1.	-
ct2	Specifies service type 2.	-
ct3	Specifies service type 3.	-
ct4	Specifies service type 4.	-
ct5	Specifies service type 5.	-
ct6	Specifies service type 6.	-
ct7	Specifies the service type 7.	-
priority priority	Specifies the priority. The priority here refers to the CR-LSP (Constraint-based Routed Label Switch Path) priority in the TE-class mapping table, not the EXP value in the MPLS header. A CR-LSP can be set up only when both <CT, setup-priority> and <CT, hold-priority> exist in the TE-class mapping table. For example, assume that the TE-class mapping table of a node contains only TE-Class [0] = <CT0, 6> and TE-Class [1] = <CT0, 7>, only the following three types of CR-LSPs can be set up successfully (the setup priority of a CR-LSP cannot be higher than the holding priority; therefore, the combination of setup-priority = 6 and hold-priority = 7 does not exist): Class-Type=CT0, setup-priority=6, hold-priority=6; Class-Type=CT0, setup-priority=7, hold-priority=6; Class-Type=CT0, setup-priority=7, hold-priority=7.	The preemption priority ranges from 0 to 7. A smaller value indicates a higher priority.
description description-info	Specifies the description of a TE-class.	The value is a string of 1 to 31 characters.
te-class1	Configures TE-Class 1.	-
te-class2	Configures TE-Class 2.	-
te-class3	Configures TE-Class 3.	-
te-class4	Configures TE-Class 4.	-
te-class5	Configures TE-Class 5.	-
te-class6	Configures TE-Class 6.	-
te-class7	Configures TE-Class 7.	-
te-class0	Configures TE-Class 0.	-

Usage Guidelines

Usage Scenario

A TE-class mapping table has been created using the te-class-mapping command.

The relationship between CT, priorities, and LSP preemption is as follows:

In MAM and extended MAN, a higher-priority LSP preempts the bandwidth of a lower-priority LSP with the same CT. LSPs with different CTs do not preempt each other.
In the RDM, the preemption relationship among CTs is: In the case of 0 ≤ m < ≤7 and 0 ≤ i < j ≤ 7, CTi with priority m can preempt the bandwidth of CTi with priority n and that of CTj with priority n. The total LSP bandwidths of CTi, however, does not exceed the bandwidth of BCi.
All configured TE-classes are deleted after the undo mpls command is run in the system view or the undo mpls te command is run in the MPLS view. All configured TE-classes are also deleted after the undo te-class-mapping command is run in the system view to delete a TE-class mapping table.

Example

# Configure a TE-class mapping table and CT0, CT1, and CT2 mapped to priorities of 0, 1, and 2, respectively.
