Applying an IPv6 ACL to an Interface
This section describes how to apply IPv6 ACLs to network interfaces. You can apply an ACL to outbound
or inbound traffic on Layer 3 interfaces, or to inbound traffic on Layer 2 interfaces.
Beginning in privileged EXEC mode, follow these steps to control access to an interface:
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Identify a Layer 2 interface (for port ACLs) or Layer 3 interface
(for router ACLs) on which to apply an access list, and enter
interface configuration mode.
interface interface_id
Example:
Switch# interface interface-id
Step 2
If applying a router ACL, change the interface from Layer 2 mode
(the default) to Layer 3 mode.
no switchport
Example:
Switch# no switchport
Step 3
Configure an IPv6 address on a Layer 3 interface (for router ACLs).
This command is not required on Layer 2 interfaces or if the
interface has already been configured with an explicit IPv6 address.
ipv6 address ipv6_address
Example:
Switch# ipv6 address ipv6-address
Step 4
Apply the access list to incoming or outgoing traffic on the
interface. The out keyword is not supported for Layer 2 interfaces
(port ACLs).
ipv6 traffic-filter access-list-name
Example:
Switch# ipv6 traffic-filter
access-list-name {in | out}
Step 5
Returns to privileged EXEC mode. Alternatively, you can also
press Ctrl-Z to exit global configuration mode.
end
Example:
Switch(config)# end
Step 6
Verify the access list configuration.show running-config
Step 7
(Optional) Saves your entries in the configuration file.copy running-config startup-config
Example:
copy running-config startup-config
Step 8
Displaying IPv6 ACLs
You can display information about all configured access lists, all IPv6 access lists, or a specific access list by
using one or more of the privileged EXEC commands.
