Command Manual – QoS/ACL
Quidway S8500 Series Routing Switches
Note:
The Interface cards support the command syntax in Ethernet port view; while the
service processor cards (LSB1NATB0 cards in the context of this document)
support the command syntax in VLAN view.
Before executing the traffic-redirect command on a service processor card, you
must first configure traffic redirection in Ethernet port view to redirect Layer 3
packets of a specific VLAN to the service processor card.
Traffic redirection setting is only available for the permitted rules in the ACL.
The packet redirected to the CPU cannot be forwarded normally.
You can achieve policy route by selecting the next-hop keyword in this command.
Multicast packets are not allowed to be redirected to the service processor cards.
Related command: display qos-interface traffic-redirect. Refer to the "VLAN&QinQ"
section in the manual for the information on the traffic-redirect { nested-vlan |
modified-vlan } command.
Example
# Configure traffic redirection on the interface cards for packets that match the permit
rules in ACL 4000: packets are redirected to the port Ethernet5/1/1.the destination-vlan
ID is 4094, L3 VPN packet is permitted..

# Configure traffic redirection on a service processor card for packets that match the
permit rules in ACL 3000.
1) Redirect the packets of VLAN4 that match the permit rules in ACL 3000 to a
service processor card in Ethernet port view.

2) Redirect the packets that are distributed to the service processor card to the next
hop 202.119.85.1 and 202.119.95.1 in VLAN view.
