Default Settings for Priority Mapping
The device provides multiple priority mapping tables. The default settings are as follows:
- For the AR100&AR120&AR150&AR160&AR200 series, AR1200 series, AR2220E, and AR2204, 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, AR2204-27GE, AR2204-27GE-P, AR2204-51GE-P, AR2204-51GE-R, AR2204E, AR2204E-D, AR2202-48FE, AR2220, AR2240C, AR2240 and AR3200&AR3600 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.
