NOTE
An LPU may not support a traffic policy; therefore, applying the traffic policy in the system or in a VLAN
on the LPU fails. Run the display traffic-policy applied-record [ policy-name ] command to view the
LPU where the traffic policy takes effect.
On the X40SFC, if ports among ports 1 to 20 and ports 21 to 40 are added to the same Eth-Trunk or VLAN,
when the car command is used in the outbound direction of the Eth-Trunk or VLAN, the rate of outgoing
traffic in the Eth-Trunk or VLAN is two times the configured CAR value.
Applying a traffic policy to the system or a slot
1. Run:
system-view
The system view is displayed.
2. Run:
traffic-policy policy-name global { inbound | outbound } [ slot slot-id ]
A traffic policy is applied to the system or a slot in the inbound or outbound direction.
Only one traffic policy can be applied to the system in the inbound or outbound
direction.
Only one traffic policy can be applied to a slot in the inbound or outbound direction.
A traffic policy cannot be applied to the system and a slot simultaneously.
– After a traffic policy is applied to the system, the system performs traffic policing
for all the packets that match traffic classification rules in the inbound or outbound
direction.
– After a traffic policy is applied to a slot, the system performs traffic policing for
all the incoming or outgoing packets that match traffic classification rules on the
slot.
Applying a traffic policy to an interface
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number [.subnumber ]
The interface view is displayed.
3. Run:
traffic-policy policy-name { inbound | outbound }
A traffic policy is applied to the interface in the inbound or outbound direction.
Only one traffic policy can be applied to an interface in the inbound or outbound
direction.
After a traffic policy is applied, the system performs traffic policing for the packets
that pass through this interface and match traffic classification rules in the inbound or
outbound direction.
