NETGEAR 8800 User Manual Dynamic ACLs Dynamic ACLs are created using the CLI. They use a similar syntax and can accomplish the same actions as single rule entries used in ACL policy files. More than one dynamic ACL can be applied to an interface, and the precedence among the dynamic ACLs can be configured. By default, the priority among dynamic ACLs is established by the order in which they are configured. Note: Dynamic ACLs have a higher precedence than ACLs applied using a policy file. The steps involved in using a dynamic ACL on an interface are: • Creating the Dynamic ACL Rule on page 313 • Configuring the ACL Rule on the Interface on page 314. • Configuring ACL Priority on page 315 Creating the Dynamic ACL Rule Creating a dynamic ACL rule is similar to creating an ACL policy file rule entry. You specify the name of the dynamic ACL rule, the match conditions, and the actions and action-modifiers. You can configure a dynamic ACL to be persistent or non-persistent across system reboots. The match conditions, actions, and action-modifiers are the same as those that are available for ACL policy files (see ACL Rule Syntax on page 300). In contrast to the ACL policy file entries, dynamic ACLs are created directly in the CLI. Use the following command to create a dynamic ACL: create access-list {non-permanent} As an example of creating a dynamic ACL rule, compare an ACL policy file entry with the CLI command that creates the equivalent dynamic ACL rule. The following ACL policy file entry will drop all ICMP echo-requests: entry icmp-echo { if { protocol icmp; icmp-type echo-request; } then { deny; } } To create the equivalent dynamic ACL rule, use the following command: create access-list icmp-echo "protocol icmp;icmp-type echo-request" "deny" Chapter 13.
