Configuring ETS parameters

ETS provides committed bandwidth. To avoid packet loss caused by congestion, the device performs the
following tasks:
Uses ETS parameters to negotiate with the server adapter.
•
• Controls the server adapter's transmission speed of the specified type of traffic.
Guarantees that the transmission speed is within the committed bandwidth of the interface.
•
To configure ETS parameters, you must configure the 802.1p-to-local priority mapping and group-based
WRR queuing.
Configuring the 802.1p-to-local priority mapping
You can configure the 802.1p-to-local priority mapping either in the MQC approach or in the priority
mapping table approach. If you configure the 802.1p-to-local priority mapping in both approaches, the
configuration made in the former approach applies.
To configure the 802.1p-to-local priority mapping in the MQC approach:
Step
1. Enter system view.
2. Create a class, specify the operator of the class
as OR, and enter class view.
3. Configure the class to match packets with the
specified service provider network 802.1p
priority values.
4. Return to system view.
5. Create a traffic behavior and enter traffic
behavior view.
Command
•
(Method 1) To the outgoing
traffic of all ports:
qos apply policy policy-name
global outbound
•
(Method 2) To the outgoing
traffic of a Layer 2 Ethernet
interface:
a. Enter Layer 2 Ethernet
interface view:
interface interface-type
interface-number
b. Apply the QoS policy to
the outgoing traffic:
qos apply policy
policy-name outbound
Command
system-view
traffic classifier classifier-name operator or
if-match service-dot1p 8021p-list
quit
traffic behavior behavior-name

Remarks
•
Configurations made in system
view take effect on all ports.
•
Configurations made in Layer 2
Ethernet interface view take
effect on the interface.
