40.10 service-acl

use the service-acl command in interface Configuration mode to bind an access 
list(s) (ACL) to an interface.

Use the no form of this command to remove all ACLs from the interface.

Syntax

service-acl input

 acl-name1 [acl-name2]

no service-acl input

Parameters

acl-name—Specifies an ACL to apply to the interface. See the user guidelines. 
(Range: 0–32 characters). Use "" for empty string).

Default Configuration

No ACL is assigned.

Command Mode

Interface Configuration (Ethernet, Port-Channel) mode.

User Guidelines

The following rules govern when ACLs can be bound or unbound from an 
interface:

•

IPv4 ACLs and IPv6 ACLs can be bound together to an interface.

•

A MAC ACL cannot be bound on an interface which already has an IPv4 
ACL or IPv6 ACL bound to it.

•

Two ACLs of the same type cannot be bound to a port.

•

An ACL cannot be bound to a port that is already bound to an ACL, without 
first removing the current ACL. Both ACLs must be mentioned at the same 
time in this command.
