The DSCP priority of the packets matching the traffic classification is re-marked.
l Run:
remark local-precedence { local-precedence-name | local-precedence-value }
[ color ]
The local priority of the packets matching the traffic classification is re-marked.
In a traffic behavior, the remark 8021p command and the remark local-precedence
command cannot be used together.
NOTE
The remark cvlan-id and remark vlan-id commands are used to implement the flow-based VLAN
mapping function. For description and configuration of flow-based VLAN mapping, see VLAN Mapping
Configuration in the Quidway S7700 Smart Routing Switch Configuration Guide - Ethernet.
CAUTION
After the remark vlan-id, remark 8021p, remark cvlan-id, and nest top-most vlan-id
commands are used, the system modifies VLAN tags of packets according to the configuration.
These actions are called VLAN-based actions.
If the ACL6 rule corresponding to the VLAN-based action is based on the following information,
the VLAN-based action does not take effect:
l Source address and prefix of IPv6 packets
l Destination address and prefix of IPv6 packets
l Type and message code of ICMPv6 packets
----End
Configuring the Redirection Action
By configuring the redirection action, the S7700 redirects packets matching the traffic
classification rule to the CPU of the LPU, the specified interface, the specified next hop
address, or the label switching path (LSP).
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
traffic behavior behavior-name
A traffic behavior is created and the traffic behavior view is displayed.
Step 3 Run the following commands as required.
l Run:
redirect cpu
The packets matching the traffic classification are redirected to the CPU.
