Configuring Priority Mapping
227
Setting to Trust the
DSCP Precedence of the
Packets
Refer to Trusting the DSCP Precedence of the Packets for the description on trusting
the DSCP precedence of the packets.
You can modify the “DSCP--
>
other precedence” mapping relationship as required.
The switch also provides a DSCP->DSCP mapping table. When the remap mode is
selected, the switch will firstly obtain a new DSCP precedence by mapping the DSCP
precedence of the packet, and then search for the DSCP->other priority mapping
table according to the new DSCP precedence and assign other precedence for the
packets.
