diffserv domain
Function
The diffserv domain command creates a DiffServ domain and displays the DiffServ domain view, or displays an existing DiffServ domain view.
The undo diffserv domain command deletes a specified DiffServ domain.
By default, the system defines a DiffServ mode named default.
Usage Guidelines
Scenario
A DiffServ domain defines the mapping between the packet priority and PHB/colors packets for managing and avoiding congestion. You can run the display diffserv domain command to view the mappings and packet colors defined in the DiffServ domain.
A DiffServ domain defines the mapping between the PHBs/colors and packet priorities (802.1p and DSCP). When binding a DiffServ domain to an interface, you can run the trust command to configure 802.1p or DSCP priority mapping on the interface.
Precautions
The DiffServ domain default exists by default. In addition to this domain, the device allows a maximum of 7 DiffServ domains. You can only change the mapping for the DiffServ domain default, but cannot delete the domain.
DiffServ domains d, de, def, defa, defau, and defaul all refer to the DiffServ domain default.
