The trust upstream default command binds a DS domain to an interface to support BA classification and modify the priorities of IP packets and MPLS packets.
The undo trust upstream default command unbinds a DS domain from an interface.
By default, no DS domain is bound to an interface.
For NetEngine 8000 F1A, NetEngine 8000 F2A:
trust upstream { 5p3d | ds-domain-name | default } [ inbound | outbound ]
For NetEngine 8000 F1A, NetEngine 8000 F2A:
undo trust upstream [ 5p3d | ds-domain-name | default ] [ inbound | outbound ]
For NetEngine 8000 F1A, NetEngine 8000 F2A:
trust upstream { ds-domain-name | default }
undo trust upstream [ ds-domain-name | default ]
| Parameter | Description | Value |
|---|---|---|
| 5p3d | Specifies the 5p3d DS domain, which is predefined in the system. |
- |
| ds-domain-name | Specifies the name of a DS domain. A DS domain consists of a group of connected DS nodes that provide the same service policy and implement the same PHB set. |
The value is a string of 1 to 48 case-sensitive characters. |
| default | Specifies the default DS domain, which is predefined in the system. |
- |
| inbound | Specifies the inbound direction of a interface which the DS domain is bound. |
- |
| outbound | Specifies the outbound direction of a interface which the DS domain is bound. |

Usage Scenario
To configure the traffic policy based on BA classification on an interface (such as the priorities of IP packets and MPLS packets), you can configure a DS domain on the interface and configure the mappings between priorities and DS domains.
You can specify inbound or outbound to have the command take effect for only incoming or outgoing packets. If neither inbound nor outbound is specified, the command takes effect for both incoming and outgoing packets. If the inbound parameter is specified, the priority fields, dscp, exp, 8021p, configured in the DS domain is mapped to the internal priorities (queue, color) for the inbound interface traffic. If the outbound parameter is specified, the internal priorities (queue, color) configured in the DS domain is mapped to the priority fields, dscp, exp, 8021p, for the outbound interface traffic.Prerequisites
The DS domain specified by ds-domain-name has been created.
Precautions
After a physical interface is added to a trunk interface, BA classification is not supported on the physical interface.
The command cannot be configured on VLANIF interface. This command takes effect only for untagged packets after being configured on a Layer 2 interface configured with the port vlan-stacking ce-default-vlan stack-vlan command. This command can be delivered but does not take effect after being configured on a Layer 2 interface configured with the port vlan-stacking vlan command. This command is not supported on any other Layer 2 interface.<HUAWEI> system-view [~HUAWEI] diffserv domain 1 [~HUAWEI-dsdomain-1] quit [~HUAWEI] interface GigabitEthernet0/1/16 [*HUAWEI-GigabitEthernet0/1/16] trust upstream 1
