NOTE:
If a WLAN-ESS interface in service contains WLAN-DBSS interfaces, you cannot change its trusted packet
priority type. To change its trusted packet priority type, you must log off all online users to stop the service
the interface is providing.
Changing the port priority of an interface
If an interface does not trust any packet priority, the device uses its port priority to look for the set of
priority parameters for the incoming packets. By changing port priority, you can prioritize traffic received
on different interfaces.
To change the port priority of an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view or
port group view.
• Enter interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
Settings in interface view (Ethernet or
WLAN-ESS) take effect on the current
interface. Settings in port group view
take effect on all ports in the port group.
3. Set the port priority of
the interface.
qos priority priority-value The default is 0.
CAUTION:
•
If a WLAN-ESS interface in service contains WLAN-DBSS interfaces, you cannot modify its priority. To
do so, you must log off all online users to stop the service the interface is providing.
• For the uplink data packets encapsulated in the tunnel from an AP to an AC, the priority is fixed at class
2. For the data packets encapsulated in the tunnel from an AC to an AP, if the WLAN-ESS interface is
configured with the qos priority command and the wired interface is configured to trust the DSCP values
of incoming packets, the DSCP precedence is obtained from the lp-dscp mapping table based on the
local precedence of packets, and assigned to the packets. The CAPWAP control packets are always
assigned the highest DSCP precedence, that is, 56.
