Management interfaces
You can also use the
ip access-group
command to apply an IPv4 ACL as a router ACL to the following
interface types:
•
Layer 2 Ethernet interfaces
•
Layer 2 Ethernet port-channel interfaces
However, an ACL applied to a Layer 2 interface with the
ip access-group
command is inactive unless the
port mode changes to routed (Layer 3) mode. To apply an IPv4 ACL as a port ACL, use the
ip port
access-group
command.
The device applies router ACLs on either outbound or inbound traffic. When the device applies an ACL to
inbound traffic, the device checks inbound packets against the rules in the ACL. If the first matching rule
permits the packet, the device continues to process the packet. If the first matching rule denies the packet, the
device drops the packet and returns an ICMP host-unreachable message.
For outbound access lists, after receiving and routing a packet to an interface, the device checks the ACL. If
the first matching rule permits the packet, the device sends the packet to its destination. If the first matching
rule denies the packet, the device drops the packet and returns an ICMP host unreachable message.
If you delete the specified ACL from the device without removing the ACL from an interface, the deleted
ACL does not affect traffic on the interface.
This command does not require a license.
Examples
This example shows how to apply an IPv4 ACL named ip-acl-01 to Ethernet interface 2/1:
switch#
configure terminal
switch(config)#
interface ethernet 2/1
switch(config-if)#
ip access-group ip-acl-01 in
This example shows how to remove an IPv4 ACL named ip-acl-01 from Ethernet interface 2/1:
switch#
configure terminal
switch(config)#
interface ethernet 2/1
switch(config-if)#
no
ip access-group ip-acl-01 in
