• Flow Label. Flow label is 20-bit number that is unique to an IPv6 packet, used by end 
stations to signify quality-of-service handling in routers. Flow label can be specified 
within the range (0 to 1048575).
• IPv6 DSCP Service. 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 IPv6 header. This is 
an optional configuration. Enter an integer from 0 to 63. The IPv6 DSCP is selected 
by possibly selection one of the DSCP keyword from a drop-down menu. If a value is 
to be selected by specifying its numeric value, then select the Other option in the 
drop-down menu and a text box will appear where the numeric value of the DSCP can 
be entered.
6.  Click the Apply button.
 To delete an IPv6 rule:
1.  On the IPv6 Rules screen in the ACL Name list, select the name of the ACL that 
includes the rule to remove. 
2.  In the IPv6 Rule Table, select the check box of the rule to delete.
3.  Click the Delete button.
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 screen to assign ACL lists to ACL 
Priorities and Interfaces. 
 To bind an IP ACL to one or more interfaces:
1.  Select Security > ACL > Advanced > IP Binding Configuration.
2.  From the ACL ID list, select an existing IP ACL in which you want to add an IP ACL interface 
binding.
The packet filtering direction for ACL is Inbound, which means the IP ACL rules are 
applied to traffic entering the port.
3.  (Optionally) In the Sequence Number field, specify a sequence number to indicate the order 
of this access list relative to other access lists already assigned to this interface and 
direction. 
A low number indicates high precedence order. If a sequence number is already in use 
for this interface and direction, then the specified access list replaces the currently 
attached access list using that sequence number. If the sequence number is not specified 
by the user, then a sequence number that is one greater than the highest sequence 
number currently in use for this interface and direction will be used. The valid range is 
1–4294967295.
4.  Click the appropriate icon to expose the available ports or LAGs. 
• To add the selected ACL to a port or LAG, click the box directly below the port or LAG 
number so that a check mark displays in the box.
