Applying a Layer 3 ACL to a physical interface

Enter configure terminal to change to global configuration mode.
```
device# configure terminal
```
Enter the interface ethernet command, specifying the port number.
```
device(config)# interface ethernet 0/2
```
Enter the ip/ipv6 access-group command, specifying the ACL that you are applying to the interface.
- For IPv4 ACLs, specify the ingress or egress direction.
```
device(conf-if-eth-0/2)# ip access-group test_02 out
```
- For IPv6 ACLs, specify the ingress direction.
```
device(conf-if-eth-0/2)# ipv6 access-group stdV6ACL_1 in
```
Enter the ip/ipv6 access-group command, specifying the ACL that you are applying to the interface.
- For IPv4 ACLs, specify the ingress or egress direction.
```
device(conf-if-eth-0/2)# ip access-group test_02 out
```
- For IPv6 ACLs, specify the ingress direction.
```
device(conf-if-eth-0/2)# ipv6 access-group stdV6ACL_1 in
```

Example

The following example applies an IPv4 ACL to a physical interface.

device# configure
device(config)# interface ethernet 0/2
device(conf-if-eth-0/9)# ip access-group ipacl2 in

Example

The following example applies an IPv6 ACL to a physical interface.

device# configure
device(config)# interface ethernet 0/2
device(conf-if-eth-0/2)# ipv6 access-group ip_acl_1 in

device(conf-if-eth-0/2)# do show access-list ipv6 ip_acl_1 in
ipv6 access-list ip_acl_1 on ethernet 0/22 at Ingress (From User)
    seq 10 deny ipv6 2001:2002:1234:1::/64 2001:1001:1234:1::/64 count (Active)
