Confidential and Proprietary Information of ZTE CORPORATION 133
After data packet priority is determined by the previous priority
determination policy, the later policies are ignored. To use the
default port priority to decide the priority of the data packets
received by the port, all the following conditions shall be
satisfied.
îš„ Data packets are not data packets sent by CPU or
management data packets.
îš„ Source MAC address of the data packets cannot be the static
address or the port source priority function is disabled.
îš„ Priority of VLAN that the data packets belong to is disabled
or Priority of the VLAN of the port belongs to is disabled.
îš„ 802. 1P user priority of the port is disabled, or the data
packets are not TAG data packets.
îš„ Port DSCP priority is disabled.
After the priority control policy of the switch is configured, if the
switch receives the data frames, the data frames with higher
priority can be transmitted first to ensure the key applications.
Configuring QoS
This topic describes the configuration of QoS including the data
packet priority.
For the configuration of QoS, perform the following steps.
1. To set the mapping of the user-priority to traffic-class,
use command set qos priority-map user-priority <0-7>
traffic-class <0-3> in global configuration mode. This is
shown in
Table 201.
TABLE 200 SET QOS DSCP COMMAND
Format Mode Function
set qos priority-
map user-priority
<0-7> traffic-
class <0-3>
global config This sets the
mapping of user-
priority to traffic-
class
Result: This sets the mapping of user-priority to traffic-class.
2. To set the mapping of the DSCP to QoS profile, use
command set qos priority-map ip-priority <0-63>
traffic-class <0-3> in global configuration mode. This is
shown in
Table 201.
TABLE 201 SET QOS DSCP COMMAND
