Configure Client QoS IPv4 Class Map on the WAP125 and WAP581
The QoS feature contains Differentiated Services (DiffServ) support that allows you to classify and manage network traffic. The configuration of DiffServ begins with the configuration of a class map. A Class Map identifies the traffic that need to be policed. It works as a component of a Policy Map. Class Maps contain conditions that traffic need to match in order to be forwarded or dropped. There can be many Class Maps in a Policy Map where either one Class Map can be matched, or all Class Maps should be matched for the action specified in the Policy Map to take place. A Class Map and a Policy Map are to be created to complete the QoS configuration of an access point.
This article aims to show you how to configure a Client QoS IPv4 Class Map on the WAP125 or WAP581 access point.
220.127.116.11 — WAP125
18.104.22.168 — WAP581
Configure IPv4 Class Map
Step 1. Log in to the web-based utility and choose Access Control > Client QoS.
Note: The images on this article are taken from the WAP125. Options may vary depending on the model of your device.
Step 2. Click the Traffic Classes tab.
Step 3. Click the button to add a traffic class.
Note: You can add up to 50 class maps.
Step 4. Enter a name for the class map in the Traffic Class Name field. The name can be a combination of letters, numbers, and special characters up to 31 characters, without spaces.
Note: In this example, IPv4ClassMap is entered.
Step 5. Choose IPv4 from the Class Type drop-down list.
Note: If you want to know how to configure an IPv6 Class Map, click here. For MAC Class Map configuration, click here.
Step 6. Click the More... button.
Step 7. Choose a Protocol to match by keyword or enter a protocol ID. The options are:
All Traffic — This option allows all traffic from any protocol. If this option is chosen, all fields will be unavailable. Proceed to Step 12.
Select From List — This option lets you choose IP, ICMP, IGMP, TCP, or UDP. If this option is chosen, skip to Step 8.
Custom — This option allows you to enter a protocol ID. The protocol ID is a standard assigned by the Internet Assigned Numbers Authority (IANA). If this is chosen, proceed to Step 9.
Note: In this example, Select From List is chosen.
Step 8. (Optional) Define the protocol that needs to be matched.
IP — This option lets you enter the IP address that needs to be matched.
ICMP — This option filters Internet Control Message Protocol (ICMP) packets.
IGMP — This option filters Internet Group Management Protocol (IGMP) packets.
TCP — This option filters Transmission Control Protocol (TCP) packets.
UDP — This option filters User Datagram Protocol (UDP) packets.
Note: In this example, IP is chosen.
Step 9. Enter the custom protocol number in the Protocol field.
Note: In this example, 3 is entered.
Step 10. Choose a source port from the-drop down list. The options are:
Any — This option considers any origin port a match. If this option is chosen, proceed to Step 13.
Select From List — This option lets you match a keyword associated with the source port which becomes translated into its equivalent port number. These keywords are File Transfer Protocol (FTP), File Transfer Protocol Data (FTPDATA), http, smtp, snmp, telnet, tftp and www.
Custom — This option lets you specify a source port number which will be matched in the datagram header to an IANA port number. It can be from 0 to 65535.
Note: In this example, Any is chosen.
Step 11. Choose a destination port from the Destination Port drop-down list. The options are:
Any — This option considers any destination port a match. If this option is chosen, proceed to Step 13.
Select From List — This option lets you match a keyword associated with the source port which becomes translated into its equivalent port number. These keywords are ftp, ftpdata, http, smtp, snmp, telnet, tftp and www.
Custom — This option lets you specify a destination port number which will be matched in the datagram header to an IANA port number. It can be from 0 to 65535.
Note: In this example, FTP is chosen as the destination port.
Step 12. Choose a Service Type from the drop-down list. The options are:
Any — This option treats any type of service as a match.
IP DSCP Select from List — This option lets you choose between ftp, ftpdata, http, snmp, smtp, telnet, tftp, and www as a filter. If this option is chosen, proceed to Step 13.
IP DSCP Match to Value — This option lets you enter a custom DSCP value from 0 to 63.
IP Precedence — This option matches the IP Precedence value of the packet to the IP Precedence value defined in this field. The IP Precedence range is from 0 to 7.
IP TOS Bits/IP TOS Mask — This option uses the Type of Service (TOS) bits of the packet in the IP header as the match criteria. The IP TOS bit value is a hex value from 00 to FF. The IP TOS Mask allows you to enter a Mask value to identify the bit positions in the IP TOS Bits value that are used for comparison against the IP TOS field in a packet. The IP TOS Mask value is a two-digit hexadecimal number from 00 to FF, representing an inverted mask. The zero-valued bits in the IP TOS Mask denote the bit positions in the IP TOS bits value that are used for comparison against the IP TOS field of a packet.
Note: In this example, IP DSCP Match to Value is chosen.
