For details about the mappings from the default 802.1p priorities to PHBs and colors, from PHBs
and colors to 802.1p priorities, from DSCP priorities to PHBs and colors, from PHBs and colors
to DSCP priorities, from EXP priorities to PHBs and colors, and from PHBs and colors to EXP
priorities, see the 8021p-inbound, 8021p-outbound, ip-dscp-inbound, ip-dscp-outbound, mpls-
exp-inbound, and mpls-exp-outbound commands.

1.3.5 Applying a DiffServ Domain

After the DiffServ domain is applied to a specified interface, the S7700 performs PHB mapping
for packets passing through the interface.
Context
To map priorities of packets coming from an upstream device to PHBs and colors based on the
mappings defined in a DiffServ domain, bind the DiffServ domain to the inbound interface. The
system maps priorities of packets to PHBs and colors based on the mappings defined in the
DiffServ domain.

command on the inbound interface:
8021p-inbound 8021p-value phb service-class [ color ]
command on the outbound interface:
8021p-outbound service-class color map 8021p-value
the inbound interface:
ip-dscp-inbound dscp-value phb service-class [ color ]
the outbound interface:
ip-dscp-outbound service-class color map dscp-value
on the inbound interface:
mpls-exp-inbound exp-value phb service-class [ color ]
on the outbound interface:
mpls-exp-outbound service-class color map exp-value
NOTE
The MPLS function of the S7700 is controlled by the license. By default, the MPLS function is disabled
on the S7700. To use the MPLS function of the S7700, purchase the license from Huawei local office.
S-series boards do not support MPLS.
S-series boards do not support priority mapping in the outbound direction on an interface.
For details about S-series boards, see Board Classification in the Quidway S7700 Smart Routing Switch
Hardware Description.
If the mpls-exp-inbound and mpls-exp-outbound commands are executed on the F48TFA, G48SFA,
G48TFA, G24TFA, G48TBC, or G48SBC board, a maximum of four DiffServ domains can be configured.
