access-group mode
access-group mode
To specify the override modes (for example, VACL overrides PACL) and the non-override modes (for
example, merge or strict mode), use the access-group mode command. To return to preferred port mode,
use the no form of this command.
access-group mode {prefer {port | vlan} | merge}
no access-group mode {prefer {port | vlan} | merge}
Syntax Description
Defaults PACL override mode
Command Modes Interface configuration mode
Command History
Usage Guidelines On the Layer 2 interface, prefer port, prefer VLAN, and merge modes are supported. A Layer 2 interface
can have one IP ACL applied in either direction (one inbound and one outbound).
Examples This example shows how to make the PACL mode on the switch take effect:
(config-if)# access-group mode prefer port
This example shows how to merge applicable ACL features:
(config-if)# access-group mode merge
prefer port Specifies that the PACL mode take precedence if PACLs are configured. If no
PACL features are configured on the port, other features applicable to the
interface are merged and applied on the interface.
prefer vlan Specifies that the VLAN-based ACL mode take precedence. If no VLAN-based
ACL features are configured on the port’s VLAN, the PACL features on the port
are applied.
merge Merges applicable ACL features before they are programmed into the hardware.
Release Modification
12.1(19)EW Support for this command was introduced on the Catalyst 4500 series switch.
