Applying an IP ACL
To apply an IP ACL (standard or extended) to a physical or port channel interface, use the following
commands.
1. Enter the interface number.
CONFIGURATION mode
interface interface slot/port
2. Configure an IP address for the interface, placing it in Layer-3 mode.
INTERFACE mode
ip address ip-address
3. Apply an IP ACL to traffic entering or exiting an interface.
INTERFACE mode
ip access-group access-list-name {in} [implicit-permit] [vlan vlan-range |
vrf vrf-range]
NOTE: The number of entries allowed per ACL is hardware-dependent. For detailed
specification about entries allowed per ACL, refer to your line card documentation.
4. Apply rules to the new ACL.
INTERFACE mode
ip access-list [standard | extended] name
To view which IP ACL is applied to an interface, use the show config command in INTERFACE mode, or
use the show running-config command in EXEC mode.
Example of Viewing ACLs Applied to an Interface
