Object Description
• Configure - Configure the corresponding match criteria for the selected rule.
• Delete -
Remove the currently selected Rule from the selected ACL. These changes will
not be retained across a power cycle unless a save configuration is performed.
• Service Type Select a Service Type match condition for the extended IP ACL rule from the
pulldown menu. The possible values are IP DSCP, IP precedence, 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 a
selection is made the appropriate value can be specified.
• IP DSCP Configuration 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. 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.
Enter an integer from 0 to 63.
• IP Precedence
Configuration
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 Configuration 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.
