What should be noted when we use the marking function of the NE80E?
Version: VRP (R) software, Version 5.30 (NE40E&80E V300R002C06B285)
1. The NE80E adopts the mapping table to implement 802.1p, DSCP, IPP, and EXP. You can view the mapping table by running the display differsive domain command. By default, there is a table titled default.
2. In the scenarios where 8021p is mapped to EXP and DSCP is mapped to EXP, the mapping effect depends on the trust upstream default and trust 8021p commands. If both commands are configured, the effective one is the trust 8021p command.
3. The mapping of EXP to 8021p is effective only on the sub-interfaces.
4. The mapping of EXP to DSCP is effective only on the main interfaces.
