Specify an IP protocol to use to classify traffic by specifying its Internet Assigned Numbers
Authority (IANA) protocol number. Protocol numbers are pre-defined for a number of
common protocols. If the protocol you require does not appear in the list, select Other and
specify the appropriate number manually. You can find IANA-assigned protocol numbers on
Start port/ End port
Optionally specify the first and last port numbers in the range of ports to which this IP QoS
profile applies. To specify a single port, specify the same port number for both Start port
and End port. Port numbers are pre-defined for a number of common protocols. If the
protocol you require does not appear in the list, select Other and specify the appropriate
To accept traffic on all ports for a specified protocol, set Start port to Other and 0.
Select the priority level that will be assigned to traffic that meets the criteria specified in this
IP QoS profile.
It is strongly recommended that you reserve Very high priority for voice applications.
Upstream DiffServ tagging
Enable this option to have the AP apply differentiated services marking to upstream traffic.
Layer 3 upstream marking ensures end-to-end quality of service in your network. Data
originating on the wireless network can now be carried throughout the network (wireless
and wired) with a consistent quality of service and priority. This feature is enabled by default.
When this feature is enabled, packets received on the wireless interface that include Wi-Fi
Multimedia (WMM) QoS values are remarked using IP TOS/DiffServ values when transmitted
to the wired network.
Upstream/downstream traffic marking
Depending on the priority mechanism that is active, upstream and downstream traffic is
marked as described in this section.
