Software User Manual 12/10/09 D-Link Unified Access System Field Class Selector Class Name Class Type Class Match Selector (IPv4) Table 208: Diffserv Class Configuration Fields Description To configure a new DiffServ class, select Create. To modify or view an existing class, select the name of the class from the dropdown menu. Enter a class name. To create a new class, select the class type and click Submit. To rename an existing class, click Rename after you enter the class name. Lists all of the class types. Currently the hardware supports only the Class Type value All, which means all the various match criteria defined for the class should be satisfied for a packet match. All signifies the logical AND of all the match criteria. The menu lists all match criteria you can add to a specified class. To configure the criteria, select a match criteria from the list, and then click Add Match Criteria. The screen changes to the criteria configuration page for that class. After you configure the criteria, click Submit to apply the criteria to the class and return to the Class Configuration page. To return to the Class Configuration page without applying the criteria, click Cancel. The match criteria and configurable fields are as follows: • Destination IP Address: Requires a packet's destination IP address to match the address listed here. In the IP Address field, enter a valid destination IP address in dotted decimal format. In the IP Mask field, enter a valid subnet mask to determine which bits in the IP address are significant. Note that this is not a wildcard mask. • Destination Layer 4 Port: Requires a packet's TCP/UDP destination port to match the port you select. Select the desired L4 keyword from the list on which the rule can be based. If you select Other, the screen refreshes and a Port ID field appears. Enter a user-defined Port ID by which packets are matched to the rule. The valid range is 0- 65535. • Any: All packets are considered to match the specified class and no additional input information is needed. • IP DSCP: Matches the packet's DSCP to the class criteria's when selected. Select the DSCP type from the menu or enter a DSCP value to match. If you select Other, enter a custom value in the DSCP Value field that appears. The valid range is 0-63. • IP Precedence: Matches the packet's IP Precedence value to the class criteria's when Enter a value in the range of 0-7. • IP TOS: Matches the packet's Type of Service bits in the IP header to the class criteria's when selected and a value is entered. In the TOS Bits field, enter a two-digit hexadecimal number to match the bits in a packet's TOS field. In the TOS Mask field, specify the bit positions that are used for comparison against the IP TOS field in a packet. • Protocol: Requires a packet's layer 4 protocol to match the protocol you select. If you select Other, enter a protocol number in the field that appears. The valid range is 0255. • Reference Class: Selects a class to start referencing for criteria. If the specified class references another class, the Reference Class match criterion disappears from the match list to prevent you adding another class reference, since a specified class can reference at most one other class of the same type. Additionally, a Remove Class Reference button appears on the screen. Click the button to remove the current class reference. • Source IP Address: Requires a packet's source port IP address to match the address listed here. In the IP Address field, enter a valid source IP address in dotted decimal format. In the IP Mask field, enter a valid subnet mask to determine which bits in the IP address are significant. Note that this is not a wildcard mask. • Source Layer 4 Port: Requires a packet's TCP/UDP source port to match the port you select. Select the desired L4 keyword from the list on which the rule can be based. If you select Other, the screen refreshes and a Port ID field appears. Enter a user-defined Port ID by which packets are matched to the rule. The valid range is 0- 65535. Document 34CSFP6XXUWS-SWUM100-D7 Configuring Differentiated Services Page 329
