Default Settings for Priority Mapping

Default Settings for Priority Mapping

The device provides multiple priority mapping tables. The default settings are as follows:
  • For the AR120-S&AR150-S&AR160-S&AR200-S series, AR1200-S series and AR2204-S, the 802.1p-to-DSCP mappings are listed in Table 2-1. The output 802.1p priorities are the same as the input 802.1p priorities. The DSCP-to-802.1p mappings are listed in Table 2-3. The output DSCP priorities are the same as the input DSCP priorities. The output MPLS EXP priorities are the same as the input MPLS EXP priorities.
  • For the AR2201-48FE-S, AR2220-S, AR2240-S and AR3200-S series, the mappings from 802.1p priorities to DSCP priorities and local priorities are listed in Table 2-2. The output 802.1p priorities are the same as the input 802.1p priorities. The mappings from DSCP priorities to 802.1p priorities and local priorities are listed in Table 2-4. The output DSCP priorities are the same as the input DSCP priorities. The mappings from MPLS EXP priorities to local priorities are listed in Table 2-5. The output MPLS EXP priorities are the same as the input MPLS EXP priorities.
