Hi LSA,

Function

The trust upstream 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 command unbinds a DS domain from an interface.

Format

In the Interface view, the command format is as follows:

trust upstream { 5p3d | ds-domain-name | default } [ inbound | outbound ]

undo trust upstream { 5p3d | ds-domain-name | default } [ inbound | outbound ]

In the BD view, the command format is as follows:

trust upstream { 5p3d | ds-domain-name | default } [ inbound | outbound ]

undo trust upstream [ inbound | outbound ]

For more information, please refer to https://support.huawei.com/hedex/hdx.do?docid=EDOC1100038601&id=trust_upstream&lang=en

I hope it helps!

The trust upstream command binds DS domain on an interface to support BA and modify the priorities of IP packets and MPLS packets.

The undo trust upstream command removes the binding.

diffserv domain
Function

The diffserv domain command defines a DS domain. If the domain has been created, then enter the domain view.

The undo diffserv domain command deletes a user-defined DS domain.
Format

diffserv domain ds-domain-name

undo diffserv domain ds-domain-name
Example

# Define a DS domain named d1.

[HUAWEI] diffserv domain d1

Hi,
In my understanding, the trust upstream command is used to trust the priority sent from the upstream device so that packets can enter the corresponding queue for forwarding.
If the command is not configured, all traffic is forwarded through the BE queue.
