FS728TP Smart Switch Software Administration Manual • Destination L4 Port Number: If the destination L4 keyword is Other, enter a user-defined Port ID by which packets are matched to the rule. • Service Type. Choose one of the Service Type match conditions for the extended IP ACL rule. The possible values are IP DSCP and IP TOS, which are alternative ways of specifying a match criterion for the same Service Type field in the IP header; however, each uses a different user notation. After you select the service type, specify the value associated with the type. • IP DSCP: Specify the IP DiffServ Code Point (DSCP) value. The DSCP is defined as the high-order six bits of the Service Type octet in the IP header. Select an IP DSCP value from the menu. To specify a numeric value in the available field, select Other from the menu and type an integer from 0 to 63 in the field. • IP TOS Bits: Matches on the Type of Service bits in the IP header when checked. In the first TOS field, specify the two-digit hexadecimal TOS number. The second field is for the TOS Mask, which specifies the bit positions that are used for comparison against the IP TOS field in a packet. The TOS Mask value is a two-digit hexadecimal number from 00 to ff, representing an inverted (i.e. wildcard) mask. The zero-valued bits in the TOS Mask denote the bit positions in the TOS Bits value that are used for comparison against the IP TOS field of a packet. For example, to check for an IP TOS value having bits 7 and 5 set and bit 1 clear, where bit 7 is most significant, use a TOS Bits value of a0 and a TOS Mask of 00. 3. To delete an IP ACL rule, select the check box associated with the rule, and then click Delete. 4. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. 5. To modify an existing IP Extended ACL rule, click the Rule ID. The number is a hyperlink to the Extended ACL Rule Configuration page. 6. If you modify the rule, click Apply to submit the changes to the switch. IP Binding Configuration When an ACL is bound to an interface, all the rules that have been defined are applied to the selected interface. Use the IP Binding Configuration page to assign ACL lists to ACL Priorities and Interfaces. To display the IP Binding Configuration page, click Security  ACL, then click the Advanced  IP Binding Configuration link. Chapter 5: Managing Device Security | 185
