However, you are not recommended to assign a system index if not urgently
necessary.

■ For MPLS packets, other than that the dscp-value stands for their DSCP priority
value, the dscp-value is also mapped to the EXP. You set the EXP value when
defining the dscp-value. Note that when the Switch 8800 Family switch is used
as the ingress PE: for IP packets, EXP is matched according to the
"DSCP+Conform-Level -> Service parameters" mapping table; for TCP and
UDP packets, the value of EXP is the lower 3 bits of dscp-value. When the
Switch 8800 Family switch is used as ingress P, the value of EXP is the lower 3
bits of dscp-value.
■ The DSCP + Conform-Level 0 -> Service parameters mapping table and the EXP
+ Conform-Level -> Service parameters mapping table (the mapping table for
conform level 0) is used here.
See the corresponding Command Manual for details of the commands.
Configuring Traffic
Redirection
Traffic redirection changes packet forwarding direction, to CPU, other ports, other
IP addresses or other cards.
For interface cards, perform the following configurations in Ethernet port view.
