Class Order
The COS mappings on the QoS and Advanced QoS Configuration panels may yield conflicting
results for ingress packet priority. Use the Class Order tab (Figure 85) to specify the order in which
to apply each of the rules. When a packet arrives at the AP, the AP checks to see whether a
mapping exists for the first rule in the class order list. If so, that mapping is applied to the packet. If
not, the AP checks whether a mapping exists for the second rule. If so, that mapping is applied. If
not, the AP continues down the class order list.
The default class order for non-VLAN tagged frames on the Ethernet interface (eth0) is:
• DSCP
• VLAN
• Interface
The default class order for the wlan0 and wlan1 interfaces is:
• TCID
• DSCP
• MAC
• VLAN
• Interface
You can also select IP Protocol and IP Precedence to include in the class order.
