ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual Type field in the IP header, however each uses a different user notation. After a selection is made the appropriate value can be specified. • IP DSCP - Specify the IP DiffServ Code Point (DSCP) field. The DSCP is defined as the high-order six bits of the Service Type octet in the IP header. This is an optional configuration. Enter an integer from 0 to 63. The IP DSCP is selected by possibly selection one of the DSCP keyword from a dropdown box. If a value is to be selected by specifying its numeric value, then select the 'Other' option in the dropdown box and a text box will appear where the numeric value of the DSCP can be entered. • IP Precedence - The IP Precedence field in a packet is defined as the high-order three bits of the Service Type octet in the IP header. This is an optional configuration. Enter an integer from 0 to 7. • IP TOS - The IP TOS field in a packet is defined as all eight bits of the Service Type octet in the IP header. The TOS Bits value is a hexadecimal number from 00 to FF. The TOS Mask value is a hexadecimal number from 00 to FF. The TOS Mask denotes the bit positions in the TOS Bits value that are used for comparison against the IP TOS field in 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 0xA0 and a TOS Mask of 0xFF. This is an optional configuration. 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.
