Defining a Rule (ACE) for an IPv6-based ACL 
STEP 1 Click Access Control > IPv6 Based ACE. The IPv6 Based ACE Page opens.
This window displays the ACE (rules) for a specified ACL (group of rules).
STEP  2 Select an ACL, and click Go. All currently-defined IP ACEs for the selected ACL are 
displayed.
STEP  3 Click Add. The Add IPv6 Based ACE Page opens.
STEP  4 Enter the parameters.
• ACL Name—Displays the name of the ACL to which an ACE is being added.
• Priority—Enter the priority. ACEs with higher priority are processed first.
• Action—Select the action assigned to the packet matching the ACE. The 
options are as follows:
- Permit—Forward packets that meet the ACE criteria.
- Deny—Drop packets that meet the ACE criteria.
- Shutdown—Drop packets that meet the ACE criteria, and disable the 
port to which the packets were addressed. Ports are reactivated from the 
Port Management page.
• Protocol—Select to create an ACE based on a specific protocol. Select Any 
(IPv6) to accept all IP protocols. Otherwise select one of the following 
protocols:
- TCP—Transmission Control Protocol. Enables two hosts to communicate 
and exchange data streams. TCP guarantees packet delivery, and 
guarantees that packets are transmitted and received in the order they 
were sent.
- UDP—User Datagram Protocol. Transmits packets but does not 
guarantee their delivery.
- ICMP—Matches packets to the Internet Control Message Protocol 
(ICMP). 
• Protocol ID to Match—Enter the ID of the protocol to be matched.
• Source IP Address—Select Any if all source address are acceptable or 
User defined to enter a source address or range of source addresses.
