Configuring PFC QoS
With a PFC3 and Release 12.2(18)SXD and later releases, you can configure named ACLs that filter
ARP traffic (EtherType 0x0806) for QoS.
To configure an ARP ACL for QoS filtering, perform this task:
Command
Step 1
Router(config)# arp access-list list_name
Router(config)# no arp access-list list_name
Step 2
Router(config-arp-nacl)# {permit | deny} {ip {any
| host sender_ip | sender_ip
sender_ip_wildcardmask } mac any
Router(config-arp-nacl)# no {permit | deny} {ip
{any | host sender_ip | sender_ip
sender_ip_wildcardmask } mac any
When configuring an entry in an ARP ACL for QoS filtering, note the following information:

This example shows how to create an ARP ACL named arp_filtering that only permits ARP traffic from
IP address 1.1.1.1:
Router(config)# arp access-list arp_filtering
Router(config-arp-nacl)# permit ip host 1.1.1.1 mac any

Creating a Class Map
To create a class map, perform this task:
Command
Router(config)# class-map class_name
Router(config)# no class-map class_name

This publication describes the ARP ACL syntax that is supported in hardware by the PFC3. Any
other ARP ACL syntax displayed by the CLI help when you enter a question mark ("?") is not
supported and cannot be used to filter ARP traffic for QoS.
ACLs entries are scanned in the order you enter them. The first matching entry is used. To improve
performance, place the most commonly used entries near the beginning of the ACL.
An implicit deny ip any mac any entry exists at the end of an ACL unless you include an explicit
permit ip any mac any entry at the end of the list.
All new entries to an existing list are placed at the end of the list. You cannot add entries to the
middle of a list.
