Step Command Remarks
10. Redirect traffic to a specified
target.
redirect { cpu | next-hop { ipv4-add
[ track track-entry-number ] [ ipv4-add
[ track track-entry-number ] ] | ipv6-add
[ interface-type interface-number ] [ track
track-entry-number ] [ ipv6-add
[ interface-type interface-number ] [ track
track-entry-number ] ] } [ fail-action
{ discard | forward } ] | vpn-instance
vpn-instance-name }
11. Set the DSCP value for
packets.
remark dscp dscp-value
12. Set the 802.1p priority for
packets.
remark dot1p 8021p
13. Set the drop precedence for
packets.
remark drop-precedence
drop-precedence-value
14. Set the IP precedence for
packets.
remark ip-precedence
ip-precedence-value
15. Set the local precedence for
packets.
remark local-precedence
local-precedence
16. Set the EXP value for MPLS
packets.
remark mpls-exp exp-value
17. Assign priority values to
packets using a specified
priority mapping table.
primap { pre-defined { color { up-dot1p
| up-dscp | up-exp | up-lp } |
dscp-dscp } | color-map-dp }
18. Configure the default traffic
redirecting action.
redirect-default next-hop ipv4-add1
[ track track-entry-number ] [ ipv4-add2
[ track track-entry-number ] ]
19. Display traffic behavior
configuration information.
display traffic behavior user-defined
[ behavior-name ] [ | { begin | exclude |
include } regular-expression ]
Optional.
Available in any view
NOTE:
•
The priority mapping table to be included in the primap pre-defined command must be configured
beforehand. For more information, see the chapter “Configuring priority mapping.”
• For an ordinary port in an isolation group, only the following commands take effect on its incoming
traffic: accounting, filter deny, car cir
committed-information-rate red discard, and mirror-to.
• In a traffic behavior, redirecting traffic to the CPU, redirecting traffic to the next hop, and redirecting
traffic to a VPN-instance cannot co-exist and the one configured the last overwrites the previous one.
Defining a policy
In a policy, you can define multiple class-behavior associations, and these associations are matched in
the order they are configured. A behavior is performed for an associated class of packets. In this way,
various QoS features can be implemented.
To define a policy:
