traffic-redirect

The system can set service parameters for the matched traffic in one of following
modes:
1 Employ the service parameters automatically allocated by the switch. Upon
receiving a packet, the switch allocates a set of service parameters for it according
to a specific rule. To choose this mode, you should select the auto keyword in this
command.
2 Choose service parameters from the "DSCP + Conform-Level ->
Service-parameter" mapping table according to packet DSCP value and conform
level. To choose this mode, you should select the remark-policed-service
trust-dscp keyword in this command.
3 Choose service parameters from the " DSCP + Conform-Level ->
Service-parameter " mapping table or " EXP + Conform-Level ->
Service-parameter " mapping table according to user's DSCP priority or EXP value
of MPLS packets and packet conform level. To choose this mode, you should select
the remark-policed-service dscp dscp-value parameter in this command.
4 Customize a set of service parameters. To choose this mode, you should select the
remark-policed-service untrusted dscp dscp-value cos cos-value
local-precedence local-precedence drop-priority drop-level parameter in this
command.
The "DSCP + Conform-Level -> Service-parameter" mapping table and " EXP +
■
Conform-Level -> Service-parameter " mapping table here is that for the
conform level 0.
Before selecting the second or third mode, you should make sure that you have
■
configured the "DSCP + Conform-Level -> Service-parameter" mapping table
and " EXP + Conform-Level -> Service-parameter " mapping table. For more
information about this mapping table, see the qos conform-level, dscp and
exp commands.
