Mapping from Priorities to CoS Values (PHBs) and Colors in the Inbound Direction on an Interface in the DiffServ Domain

  • Table 13-3 describes the mapping from 802.1p priorities to CoS values (PHBs) and colors in the inbound direction on an interface in the DiffServ domain.
  • Table 13-4 describes the mapping from DSCP priorities in IP packets to CoS values (PHBs) and colors in the inbound direction on an interface in the DiffServ domain.
NOTE:
The mapping from interface priorities to CoS values (PHBs) and colors is similar to the mapping from 802.1p priorities to CoS values (PHBs) and colors. The color is used to determine whether the packets are discarded, and is independent of the mapping between internal priorities and queues.

Mapping Between CoS Values and Interface Queue Indexes

  • Table 13-5 describes the mapping between CoS values and queue indexes supported by the CX31x&CX91x series switch module 10GE switching planes and CX710 switch module 40GE converged switching plane.
  • Table 13-6 describes the mapping between CoS values and queue indexes supported by the CX11x switch module GE switching plane.

Mapping from CoS Values (PHBs) and Colors to Priorities in the Outbound Direction on an Interface in the DiffServ Domain

  • Table 13-7 describes the mapping from CoS values (PHBs) and colors to 802.1p priorities in the outbound direction on an interface in the DiffServ domain.
  • Table 13-8 describes the mapping from CoS values (PHBs) and colors to DSCP priorities in IP packets in the outbound direction on an interface in the DiffServ domain.
NOTE:
The mapping from CoS values (PHBs) and colors to interface priorities is similar to the mapping from CoS values (PHBs) and colors to 802.1p priorities. The color is used to determine whether the packets are discarded, and is independent of the mapping between internal priorities and queues.
